Hello,<br>
<br>
On IRC, I was suggesting that Krita start to using RGB 16bits as a default<br>
when creating images. I don't think there is a good reason to create 8bits<br>
image files nowdays. Of course, when you open an exisiting 8bits image, krita<br>
would still open it as 8bits. Despite most display being limited to 6-8bits<br>
display, when drawing, 16bits reduce most of the errors due to limited 8bits<br>
range.<br>
<br>
This also raise the discussion of wether to use sRGB (2.2 gamma) or scRGB<br>
(linear in light) profile.<br>
<br>
In favor of sRGB:<br>
* when saving to PNG or JPEG, krita embedd the color profile, but, most<br>
<br>
In favor of scRGB:<br>
* Fix a lot of gamma imperfection, for instance like scaling:<br>

<br>
<br>
An alternative could be to use scRGB in Krita, and then to add a "convert to<br>
sRGB" option in png, jpeg and tiff that would be checked by default.<br>
