How do the images look just using the browser as would be the case if we were looking at Annual Challenge entries. I understand that we should use a colour managed browser like Chrome. If you have exported your images using LR export, can you still view the images in the LR Library and, if so are they OK then (I always tick “add to this catalogue” so I will be able to see them)? I cannot think of anything obvious. I certainly use LR export to resize, convert to sRGB and save as JPEG. I notice that this topic has come up on the Adobe Forum but seemed inconclusive as it was unclear whether those who had the problem had calibrated their monitors etc.
