A little unsharp masking (edge sharpening/enhancement) could really help with some of these. For example, with this blurry image: #000890 2011-07-29.


There are eggs there to be seen, but against a light-colored background, it's a thankless task.

If you didn't want to permanently alter the images, you could add this as a user-selectable in-browser based function (I suspect).

To follow up...

I just did a test with a screenshot -- the edge sharpening really does help, particularly with recognizing the specular highlights from the flash that one looks for (e.g. on eggs).

A previous version of Broodmapper, implemented in Java, had image sharpening.  I haven't been able to get it to work well in the JavaScript version, so it has been removed. 

The "Invert" function may also be useful to you in locating the eggs.

Yes, thanks -- the Invert Image function does help.


And because the letter is not underlined on the "key", I'll mention here that it has its own keyboard shortcut: I
