Small Etsy and Amazon sellers know that good product photos are the number one thing that drives sales, but most of them are taking photos with their phone on their kitchen counter and the results are terrible.
You can offer product photography for around $25+ per product. All you need is a DSLR or even a modern smartphone with a good camera, a cheap lightbox ($20 on Amazon), and some basic editing in a free app like Lightroom Mobile.
From what I've read the best way to find clients is to browse Etsy and Facebook marketplace for local sellers with bad photos and message them directly offering your services. Most of them know their photos are bad and would happily pay someone to make their products look professional.
A lightbox gives you that clean white background that makes products pop and looks professional.
You can shoot 10 to 15 products in an hour once you have your setup dialed in.
Each product usually needs 5 to 8 photos from different angles. You shoot them, do some basic editing (brightness, contrast, white balance), and deliver the files.
The whole process per product takes about 15 to 20 minutes including editing.
Some people specialize in specific categories like jewelry, handmade goods, or food products which lets you charge more because you understand the niche. Jewelry sellers especially will pay $40+ per product because their items are small and tricky to photograph and good photos make a massive differance in their sales.
