My first post, so I'm not sure if this is the correct place to pose this related query. I am moving from Aperture to Lightroom, as pushed by Apple. My issue is being certain after cropping that I am meeting the size Alamy criteria, as the newly downloaded Lightroom and Photoshop DO NOT include the TIFF format, hence unable to check the image against the 17MB Tiff criteria. Am I OK just to check that the pixel count before exporting as high quality jpeg is over the 6 million level? I am using DX Nikons so sensor size is no issue.
