I have been uploading my photos (800 x 600 pixels) as jpeg compressed with quality 12 (maximum). The file size is typically 150 KB. When I look at the image in Auctiva, the file size is typically 35 KB. So presumably Auctiva opens the jpeg and saves again at quality 5 (medium)? If that's the case, I might as well upload jpegs at quality 5 (medium) to start with? Have I understood this right?
When I compare my image before uploading with the images in Auctiva, I can clearly see an increased contrast and vibrance in the Auctiva version of the image. I think Auctiva must be adjusting the image in the upload process? With the type of items I sell, an adjustment is unfortunate - the image in Auctiva must represent the original item precisely. Can I stop this adjustment?
Any advice anyone can give would be greatly appreciated.
