Are you comfortable photographing yourself? It took me quite sometime to get exactly what I wanted (trial and error
You can use a cell phone for product photos.
Tips: Use a grid view on your phone camera and ensure you always keep your products within the lines ( I keep my products in the 4 center squares of my grid so when I crop the photo's Square they all land in the same sight line).
Use a Tripod - if you can set up a photographing kit in your office or home this is ideal. I even photograph at the same time of day for lighting.
Use a white paper roll ( backdrop) and get a photography kit with all Backdrop Stand & leave it set up and ready to go.
Edit on your cellphone and post right to your shopify store for ease. Note: Any inconsistencies with line up of products on the collection page can be fixed with Shopify Apps that keep photo's square ect - I use these apps only when needed and then delete them after it's all good but find even just editing the pic in shopify works.
After you've done this a few times you'll find what you really like and are able to change as you learn and see things you like in other shops.
I hope this is helpful
