Bo - I am attempting to send my photos into Alamy.com. Their requirements are for JPEG's at 17mb or higher. The files are ultimately set for sale.
The quality of the image seems great to me but if requirements are for 17mb, even if the 10mb looks great, I'm not sure it will be acceptable. I do, however, have a question about quality over file size into Alamy.com in hopes that it can still be acceptable.
All is saved in PSD form. I have a very good understanding about JPG as a lossy format and it's not being editable once it's created. My issue, as I had stated, was about the differences in file sizes of the same picture but of slightly different edits. It seems like, JJ was able to rectify my understanding of this size issue.
Everyone has been very helpful. It seems that if I am to have this one photo accepted, sans the noise and sharpness as recommended by Alamy, I will need ensure they can accept the lower MB but still a high quality JPG.
