Cormorants and egret

There is a software Topaz Gigapixel. It'd be useful in such case.

Hi Serge, thanks. To do what ? I have a Lightroom workflow plus photoshop here and there and I am fine with it. Light was awful due to heavy rain and body old gen + apsc. Technical quality was not priority so was ambiance ! But intéressée to get more méat fromyour comment if you agree. All the best. Eric

you can see screenshots.

Install it, open low quality photo, set the required settings, "Update", then save the image to disk. Further as usual in LR and PS. You can repeat two or more times, for e.g. enlage x2, than x0,5, sometimes it help.

But, of course initial image must be sharp, so this not a "silver bullet".
