GRAND RAPIDS, Mich. (WOOD) — A new exhibition at the Division Avenue Arts Collective is showcasing the struggles of ADHD and autism through astrophotography.
Artist Kae Pershon started the collection over a year ago as a continuation of her ongoing series entitled “(less).”
“Each of these exhibits deals with different symptoms or experiences (of) someone who has ADHD or who has a neurodivergence” including time blindness, emotional dysregulation, and memory, she said.
The portion of Pershon’s series on display at DAAC, entitled “End(less),” speaks to executive dysfunction, described by the Cleveland Clinic as “a behavioral symptom that disrupts a person’s ability to manage their own thoughts, emotions and actions.”
“A lot of times it’s looked at like a paralysis because you become so overwhelmed and you freeze. You know you’re supposed to be doing something but you can’t really put it together in your mind to actually get started,” Pershon said.

The exhibit consists of 33 photos of nightscapes in a variety of sizes.
“I knew that when I started this, I wanted astrophotography for executive dysfunction just because I remember growing up, I grew up in a very rural area in Michigan, and getting those big moments of awe and overwhelming feeling when you’re looking at the night sky. It can feel very similar in that kind of vein,” Pershon, who has ADHD, said.
“My hope is that when someone looks at this exhibit either if they themselves have a neurodivergency can feel some sort of relation and know that they are not alone in their struggle … or if it’s someone who may not experience those things can look at it through a new lens and go ‘Oh, OK. I didn’t realize this is what it’s like to experience that.’ And it can kind of help break down those stereotypes or stigmas,” she explained.
The opening reception is being held Friday from 6 p.m. to 9 p.m. at DAAC, located at 1553 Plainfield Ave NE near Lafayette Avenue. Pershon will be there to answer any questions or talk about ADHD and autism.
The exhibition will be on display until July 7. It can be viewed during events at the DAAC. Anyone who is interested in viewing the exhibition outside of those times or would like Pershon there is asked to reach out on Facebook or Instagram.
A closing reception will be held on July 7 from 6 p.m. to 9 p.m.

Headshot photography entails creating photos that look natural and authentic for casting directors or employers to see the real you in these photographs.
Light
Headshot photography requires making sure that the subject’s face is properly illuminated. Therefore, for best results it is often shot using natural or soft artificial lighting without harsh shadows and glare, as well as featuring an uncluttered background that keeps the focus solely on their face.
While many assume a quality headshot must include full-length photos, this isn’t always necessary. Some actors prefer head and shoulders shots because they find them easier for conveying emotions and range with their faces.
When posing clients, photographers will encourage them to use various facial expressions such as frowning, puckering the forehead/eyebrows, squinting eyes, crinkle eyebrows or make other facial movements while playing around with different smirks and smiles for optimal results.
Headshots typically call for one light that illuminates all aspects of the subject’s face – either inside a studio, outdoors or both. Adding another light can provide more dramatic or vignette effects behind the subject and ensure a high shutter speed to minimize camera shake or subject movement during shooting.
Composition
An effective headshot will showcase you in their best light. However, in order to do this successfully, lighting and composition must also be considered when taking this image. You can visit this site for more information on taking good photographs.
A photographer will start by talking to you about what you expect out of their session in order to gain insight into its overall theme and style. They will suggest settings and compositions to highlight your best features.
For example, a professional actor’s headshot must feature their face and eyes for maximum impact; on the other hand, those looking to establish themselves as executives or thought leaders might opt for more full-body shots with vibrant backdrops.
Photoshop or another photo-editing software can also help enhance the image quality of your headshots, from fixing white balance and exposure adjustments, to adding contrast that brings out details in eyes.
Furthermore, higher-level retouching may also be used to soften skin or remove blemishes – but take care not to go overboard. A Vancouver headshot photographer may also offer this service as an add-on. Be sure to inquire up front to ensure it is available if you are interested in this service.
Background
Though professional headshots focus on the face, their surroundings also play a pivotal role. A corporate job may require an objective backdrop while creative industries often prefer bold colors or unusual textures. Color and personal taste should all be considered when selecting an ideal backdrop.
White remains the go-to headshot background, but a professional photographer should offer clients alternative choices as well. Grey offers an ideal alternative, giving your headshot a more subdued aesthetic. A dark background has also become increasingly popular for creative industries professionals; creating an ethereal aesthetic and helping outfit colors pop!
Your options for backgrounds range from brick walls, buildings, textures such as lines or plant life; beautiful natural scenery like lakes, woods or flower fields may also work; for more formal headshots you could use your studio or business’s location as the setting. You can visit https://www.pinterest.com/ for more background ideas.
Some subjects may desire photographs with more natural backgrounds that they can use on social media, their website and printed materials to represent themselves more authentically. This may be especially applicable to thought leaders, business professionals and others looking to showcase their personality through photographs.
Getting Started
Before a headshot session begins, it is crucial that both you and the photographer have an understanding of where it will be displayed; this will allow them to plan the most effective shoot in order to obtain the best photo.
Headshots should go beyond mere visual identification; they should convey more about an individual’s character and attitude. The best photographers will have a mastery of people skills in order to help you feel relaxed while eliciting genuine expressions.
Before beginning a shoot, it is crucial that a pre-session consultation be held between photographer and client either in-person or over the phone. This consultation allows photographers to get acquainted with their clients while discussing desired looks as well as any concerns or queries the client might have.
A good photographer will help you bring your ideal headshot to life.

[ Key Features ]
1. Ultra wide-angle 14mm with a maximum aperture of F1.4 and outstanding optical performance
This world-first performance was achieved by applying the best of SIGMA’s optical technologies, from the design to the lens manufacturing process. 19 elements in 15 groups, including 1 SLD glass element, 3 FLD glass elements, and 4 aspherical lens elements, make up a luxurious lens configuration. This allows for advanced aberration correction and a high degree of precision in the lens construction. This allows both advanced aberration correction and F1.4 brightness. In particular, sagittal coma flare, which distorts the shape of stars, has been carefully corrected, and even at the widest aperture, the lens delivers high image reproducibility right to the periphery of the image. Ghosting and flare are also thoroughly addressed through both optical design and coatings. This allows for clear, crisp shooting of starry sky and night scenes. Optimized for starscapes, which require extremely high performance, this lens delivers images that exceed expectations in any scene, including landscapes, architecture snapshots, portraits, and indoor photography.
2. Abundant functions and accessories to support starscape photography
The 14mm F1.4 DG DN | Art is equipped with a wealth of features to support starscape photography. This fully backs up the fun of starscape photography.
Includes a detachable tripod mount compatible with Arca-Swiss type. The 14mm F1.4 DG DN | Art can be mounted on a tripod in a more stable condition, as it is heavier on the front side. The shape is designed to prevent interference even when using the lens heater.
MFL (Manual Focus Lock) Switch
A switch to lock the manual focus at a desired position. Prevents focus shift caused by unintentional operation of the focus ring. This is useful for long time exposure photography, etc., where the focus is fixed.
Steps around the front and lens heater retainers prevent the lens heater* from protruding into the front of the lens and causing vignetting on the periphery of the screen.
* A belt-shaped heater that is wrapped around the lens to prevent condensation from forming inside the lens when the temperature drops.
A rear filter holder is provided as standard equipment at the lens mount for attaching a sheet-type rear filter. A lock mechanism is also provided to prevent the filter from falling out.
Special front cap with locking mechanism and filter slots
Includes a cover-type front cap with locking mechanism. It also has a newly developed filter slot that can hold two rear filters depending on the application. The cap is specially designed for the 14mm F1.4 DG DN | Art to protect the sheet filters from scratches and dirt while ensuring that they are not mistakenly taken out or forgotten.
3. Signature Art line features and high build quality
In addition to functions specifically designed for shooting starscapes, the lens is equipped with various functions to assist in shooting, including an AFL button to which any function can be assigned and an aperture ring. The body is dust and splash resistant, and the frontmost surface of the lens is coated with a water- and stain-repellent coating, so you can shoot outdoors in harsh environments with peace of mind. The HLA (High-response Linear Actuator) enables high-speed, quiet, and highly accurate autofocusing.
In order to maintain performance while supporting a lens with a large aperture, the lens has a robust internal structure and uses lightweight materials such as polycarbonate TSC (Thermally Stable Composite), which has a thermal shrinkage rate equivalent to that of aluminum, and magnesium in appropriate locations to reduce weight while ensuring robustness. The lens body is built with the high build quality of the Art line specifications, allowing the user to fully enjoy the unique performance of the lens in any environment, including shooting starscapes.

Sigma has announced the first full-frame 14mm lens with a maximum aperture of f/1.4. The Sigma 14mm F1.4 DG DN Art , price £1399.99 / $1599.99, will be available with the L-mount or Sony E-mount. As yet we have no information about whether it will become available in any other mounts.
That large aperture means that the Sigma 14mm F1.4 DG DN Art is two-thirds of a stop brighter than the Sigma 14mm F1.8 DG HSM Art for DSLR cameras. Consequently, the new lens allows 58% more light to reach the camera’s imaging sensor. That’s great news for use in low light and capturing images of the night sky.
The lens is designed with astrophotography in mind and it’s constructed from 19 elements arranged in 15 groups with 1 SLD (Special Low Dispersion), 3 FLD (‘F’ Low Dispersion) and 4 aspherical elements. Sigma has paid particular attention to the image quality when the focus is at infinity and sagittal coma flare is said to be controlled very well so that small, bright points of light are super-sharp across the frame and at every aperture setting. This optical design also ensures good corner sharpness and well-controlled chromatic aberration.
Meanwhile, in-camera optical aberration correction profiles deal with any distortion or vignetting to help keep the lens’ size and weight down.
The Sigma 14mm F1.4 DG DN Art features an aperture ring with an ‘A’ for auto setting to hand over control to the camera. This ring can be used with a click or ‘de-clicked’.
Like the Sigma 20mm F1.4, DG DN Art, the 14mm F1.4 DG DN Art has a Lens Heater Retainer to keep a heat strip in place to prevent condensation from building up on the front element in cold conditions.
In addition, there’s a filter holder at the end of the lens that accepts gel filter sheets. The lens comes with a cap with a holder for two of these soft filters.
There’s a manual focus lock (MFL) on the side of the barrel to enable photographers to set the focus to infinity and then lock it in place. There’s also an AFL button that can be customised to access useful features, including an autofocus lock.
To help deal with the weight that is an inevitable aspect of such a wide, larger aperture lens, Sigma supplies the TS-141 Tripod Socket in the box to deliver a more balanced arrangement when the camera and lens are mounted on a tripod.
The 14mm F1.4 DG DN is the third lens to feature Sigma’s new High-response Linear Actuator (HLA) motor to enable faster, smoother, quieter and more accurate focusing than a stepping motor.

Key Takeaways
Users on social media are touting a drugstore supplement called berberine as “nature’s Ozempic.”
Berberine may be able to help manage blood sugar and cholesterol levels.
Berberine has a different mechanism of action than prescription drugs like Ozempic, and is not proven to support weight loss.
People who are considering berberine should consult with their healthcare provider before trying it.
An over-the-counter dietary supplement called berberine is being labeled as a “natural” dupe for Ozempic, a prescription medication used to stabilize blood sugar and may help patients with type 2 diabetes lose weight.
Users all over social media are claiming that the supplement can help lower blood glucose, improve insulin sensitivity, and go as far as helping people shed a few pounds. The search term “berberine supplement” has well over 300 million views and counting on TikTok, and #berberine has about 67 million views.
But as with all social media health hacks and trends, there’s the question of whether or not any of these claims can be backed by science. Here’s what experts have to say about berberine, and whether or not it could be a decent option for patients who can’t get their hands on popular injectable medications like Ozempic, Wegovy, or Mounjaro.
Related: What's the Difference Between Ozempic, Wegovy, and Mounjaro?
What Is Berberine and What Is It Intended For?
Berberine is a natural compound called an alkaloid that’s extracted from a variety of plants, including goldenseal, European barberry, Oregon grape, phellodendron, and tree turmeric, Lisa Kroon, PharmD, Professor and Chair of the Department of Clinical Pharmacy in the School of Pharmacy at the University of California in San Francisco, told Verywell.
People most who take berberine consume it as a supplement, which can come in many forms like capsules, tablets, liquid extracts, or powders, Kroon said. It has also been used in eye drops and gels.
While the drugstore supplement has recently increased in popularity due to social media, it’s been used for centuries, especially in Chinese and Ayurvedic medicine, Mir B Ali, MD, bariatric surgeon and medical director of MemorialCare Surgical Weight Loss Center at Orange Coast, told Verywell. In fact, providers may recommend berberine for people with diabetes to help lower their blood sugar and cholesterol.
“It has also been shown to have some antimicrobial effects so it can affect the normal intestinal bacteria,” Ali said.
Berberine is believed to have these effects is because it may target a protein involved in insulin resistance and blood sugar control, which positively impacts how our cells can utilize blood glucose, Megan Hilbert, MS, RDN, a registered dietitian specializing in gut health nutrition at Top Nutrition Coaching, told Verywell in an email. In turn, these alkaloids can “reduce the risk of diabetes and metabolic syndrome.”
According to the National Library of Medicine, berberine can also be used for burns, canker sores, liver disease, and many other conditions. But there is not enough well-studied scientific evidence to support many of these uses.
“It’s absolutely not nature’s Ozempic and does not work like Ozempic, which is a GLP-1 inhibitor,” Kroon said. “I think people are just grasping here and manufacturers of these supplements are just kind of creating a hype to try to be appealing for people looking for a magic potion to help them lose weight.”
How to Get Berberine
Berberine is available over-the-counter and can be purchased online or in stores, usually in a supplement capsule form, Hilbert said. Dosages for berberine range between 500 to 1,500 milligrams per day, but typically, it’s taken in doses of 500 milligrams, three times a day.
Depending on the online retailer or store, most berberine supplements can be purchased anywhere from $12 to 50 dollars, Hilbert added.
Comparatively, GLP-1 agonist drugs like Ozempic, Wegovy, and Mounjaro require prescriptions and can cost as much as $1,000 out of pocket.
Can Berberine Be Used For Weight Loss?
Although berberine can have similar health benefits to prescription medications when it comes to reducing blood sugar and cholesterol levels, it’s not clear if the supplement is effective when it comes to weight loss, Ali said. Diabetes drugs Ozempic and Mounjaro can be prescribed off-label for weight loss, while Wegovy is indicated for weight loss.
“People are saying that [berberine] is equivalent, but there’s no real evidence to show that it’s equivalent to those medications,” Ali said. “It has shown to have some modest amount of effect on weight loss, but it’s not the same effect as the prescribed medications.”
The reason berberine does not have the same exact effect as Ozempic is because its mechanism of action is different, Kroon said. Ozempic, which is a GLP-1 inhibitor, helps the pancreas release the right amount of insulin when a patient’s blood sugar is high, which in turn reduces their blood glucose levels. Semaglutide medications like Ozempic slow down how quickly your stomach empties food, which can lead to decreased appetite and weight loss.
“Semaglutide also helps to reduce a hormone called glucagon after we eat and that helps reduce our blood sugar. So, [Ozempic] has many ways of how it works for diabetes, including effect on weight,” Kroon said. “Berberine doesn’t work anything like that; it is a completely different mechanism.”
Instead, berberine activates an enzyme called AMP-activated protein kinase (AMPK), which can help regulate glucose metabolism, improve insulin sensitivity, and impact blood sugar levels.
Still, a bit of research on berberine’s effectiveness for weight loss and diabetes does exist. One meta-analysis of 27 studies found that the supplement may be just as effective as certain oral diabetes medications, such as metformin and glipizide, when it comes to blood glucose control. And a study from 2012 found seven people with obesity who took 500 milligrams of berberine three times per day for 12 weeks lost on average about 5 pounds of weight. More recently, a review of 12 studies from 2020 suggested that berberine supplements can potentially impact body weight, body mass index (BMI), and belly fat.
While there are some studies to suggest berberine supplements may have a positive impact on people’s health, more research is needed to draw meaningful conclusions about whether or not berberine is effective for weight loss.

Do Experts Recommend Trying Berberine?
According to Ali, deciding whether or not to use berberine supplements for weight loss should be a decision you make with your healthcare provider. Although it’s not “nature’s Ozempic,” it can be a more accessible option for some patients, especially since it does not require a prescription.
“I don’t think berberine would be harmful for the majority of patients, but it’s still not clear how effective it is for weight loss,” Ali said. “I think it’s reasonable to try it as a supplement to healthy lifestyle and diet changes, but I don’t want people to think that it’s the equivalent of prescribed medications.”
Hilbert added that even though there aren’t a lot of studies showing berberine has harmful reactions or outcomes, some people who use the supplement may experience minor side effects, including diarrhea, constipation, nausea, bloating, and other gastrointestinal issues.
“Berberine does appear to be safe for adults to use in the short-term,” said Hilbert. “But long-term use has not been studied and some animal studies report some severe side effects with long-term berberine use like enlarged liver/kidneys, muscle tremors, and gastric ulcers.”
Before you decide to use berberine, it’s important to note that these supplements are not regulated by the Food and Drug Administration (FDA) and have not been studied on a large scale, Kroon noted.
“Medications such as Ozempic and Wegovy are FDA-regulated and well-studied for indications like diabetes or weight loss, whereas nutritional supplements like berberine are not FDA regulated,” she said. “I would really advise not to jump on the bandwagon here and think that berberine is going to work like a prescription medicine, because it’s not going to. You could be spending a good $50+ out of pocket.”
What This Means For You
Experts say people who use berberine may not see the same results as other prescription medications intended for weight loss. Before trying berberine, you should speak with your healthcare provider, especially if you have certain health conditions like diabetes or are taking other medications and supplements.

[ Key Features ]
1. Ultra wide-angle 14mm with a maximum aperture of F1.4 and outstanding optical performance
This world-first performance was achieved by applying the best of SIGMA’s optical technologies, from the design to the lens manufacturing process. 19 elements in 15 groups, including 1 SLD glass element, 3 FLD glass elements, and 4 aspherical lens elements, make up a luxurious lens configuration. This allows for advanced aberration correction and a high degree of precision in the lens construction. This allows both advanced aberration correction and F1.4 brightness. In particular, sagittal coma flare, which distorts the shape of stars, has been carefully corrected, and even at the widest aperture, the lens delivers high image reproducibility right to the periphery of the image. Ghosting and flare are also thoroughly addressed through both optical design and coatings. This allows for clear, crisp shooting of starry sky and night scenes. Optimized for starscapes, which require extremely high performance, this lens delivers images that exceed expectations in any scene, including landscapes, architecture snapshots, portraits, and indoor photography.
2. Abundant functions and accessories to support starscape photography
The 14mm F1.4 DG DN | Art is equipped with a wealth of features to support starscape photography. This fully backs up the fun of starscape photography.
Includes a detachable tripod mount compatible with Arca-Swiss type. The 14mm F1.4 DG DN | Art can be mounted on a tripod in a more stable condition, as it is heavier on the front side. The shape is designed to prevent interference even when using the lens heater.
A switch to lock the manual focus at a desired position. Prevents focus shift caused by unintentional operation of the focus ring. This is useful for long time exposure photography, etc., where the focus is fixed.
Steps around the front and lens heater retainers prevent the lens heater* from protruding into the front of the lens and causing vignetting on the periphery of the screen.
* A belt-shaped heater that is wrapped around the lens to prevent condensation from forming inside the lens when the temperature drops.
A rear filter holder is provided as standard equipment at the lens mount for attaching a sheet-type rear filter. A lock mechanism is also provided to prevent the filter from falling out.
Includes a cover-type front cap with locking mechanism. It also has a newly developed filter slot that can hold two rear filters depending on the application. The cap is specially designed for the 14mm F1.4 DG DN | Art to protect the sheet filters from scratches and dirt while ensuring that they are not mistakenly taken out or forgotten.
3. Signature Art line features and high build quality
In addition to functions specifically designed for shooting starscapes, the lens is equipped with various functions to assist in shooting, including an AFL button to which any function can be assigned and an aperture ring. The body is dust and splash resistant, and the frontmost surface of the lens is coated with a water- and stain-repellent coating, so you can shoot outdoors in harsh environments with peace of mind. The HLA (High-response Linear Actuator) enables high-speed, quiet, and highly accurate autofocusing.
In order to maintain performance while supporting a lens with a large aperture, the lens has a robust internal structure and uses lightweight materials such as polycarbonate TSC (Thermally Stable Composite), which has a thermal shrinkage rate equivalent to that of aluminum, and magnesium in appropriate locations to reduce weight while ensuring robustness. The lens body is built with the high build quality of the Art line specifications, allowing the user to fully enjoy the unique performance of the lens in any environment, including shooting starscapes.
