“Tone mapping reduces global contrast in images while increasing local contrast and shadow/highlight detail.” or so Gimp Addict’s Tone Mapper tutorial says. Go and read his tutorial, I will add few comments to it:
4) “radius of 100-500 is good” — yes, it usually is, but since we don’t know the size of the image, I’d […]

Do you know what common sense is?
Common sense is:

NOT setting fixed height for elements whose actual height can change anytime, and especially not setting this particular height to three elements next to each other, to keep them with the same height (common sense solution is to wrap it all in another element)
NOT calling your database […]

As I mentioned in the previous post, I needed a CAPTCHA algorithm. As I couldn’t find anything simple and usable that would do what I want (ie follow the basic principles of captcha creation (readibility for humans, and hopefully unreadibility for machines)), I decided to write my own.

I was using “border: 1px solid red;” to determine where certain element was. This has several drawbacks… first, it adds 1px on each […]

Is it even possible that I forgot to advertize my new project on my own blog?
So… here it goes: I created tsumego collections.
