I am shooting my images with a DSLR tethered to lightroom on a macbook. I complete my edits in lightroom including crop, color correction, sharpness, brightness and saturation to achieve an "as-close-to-reality-as-possible" look for each image. I am usually able to achieve a nice crisp white background during this process, however, after images are uploaded to eBay, they lose the crisp white background which looks yellowed and dull. I then have to re-edit each image in the eBay photo editing tool which is kludgy and redundant in my process.
I am shooting in the Adobe RGB colorspace and am wondering if my issue is not colorspace related, and if I should be using sRGB instead. Anyone have experience with this!
