Hello, Thank you for showing interest in my services. I offer background removal. I provide both the transparent image that is PNG and also with a white background for your e-commerce sites.
I also offer color correction and image enhancement using Photoshop as per your requirements. Along with it I do basic retouching like removing unnecessary objects in the frame.
What the Seller needs to start the work
If possible Raw files or if not, then high resolution jpegs can work too. It will make the work much easier as well the image will not get pixelated. However if you don't have, no problem I can work on low resolution too.
