The sparrow experiment
This little house sparrow shot became the subject of a little experiment on using an online image enlarger. I fed my 12mp image into it and it became something like 16mp. Not a big enlargement by any means. I am not entirely sure that it improves resolution in any way. It is sharp enough for an image from a small sensor camera, but I couldn't see any noticeable improvement on the original, apart from the extra size. But it was interesting to try it out. Perhaps it would work better with a greater enlargement, but the one I used only seemed to allow for trying a 25% enlargement. Sadly, I cannot remember which online enlarger I used, but I don't think I will use it again. I was curious about such things with the recent news of such image enlargers using AI to improve the resolution of older or smaller image files. Also, sadly, I cannot show the original image for comparison as it was deleted accidentally after I made my own comparison! I may try other ones in the future just to see if there are any better ones out there.
This was taken through my lounge window at a distance of 7 metres from my birdbath. Original focal length would have been the 35mm equivalent of around 1800mm. Camera was the Nikon Coolpix P900.
