whoa........ thanks for the answers, guys... To my mind, at present time i'm newbie in cam modding.. Shit..... How you teach all it?!

How you think: a bigger file size give more quality or not?
For example, i set average size up to ~700 kilobytes, but original (from SE) average size is ~450 kilobytes.

So, 700kilobytes gives more quality then 450?
And what best value of quality compression? To my mind, 92-94%

In JPEG compression quality is given by the Q factor (but it's not standarized). The size is directly proportional to Q. In most cases, for values since Q=75 it's very difficult to see any quality difference, but this depens on the JPEG implementation. Q=90 does not mean 90% compression free. If you put it greater than Q=95, size will be several times bigger and the quality gain infinitesimal. JPEG is based on the Huffman coding (as well as gzip, mp3, png...)

ok, and what a Q-factor param do you use?

I know that it is a variable, no constant.

If i set Q=95, 95 was a max value

I'm using "Ultimate 2.11 vivid color" right now, and color and sharpness are pretty good. But I must say it takes a lot of time comparing all available mods, so I just use them for a week or so, and then try another.
@ jomateixa: I wouldn't mind bigger files if this resulted in higher quality pics; Ultimate 2.11 pic sizes are from about 700 kB to 900kB large. Does it have the best compromize for size and quality?
@Sonarik: Could you please start a topic on how to edit language packs with the software you use? I think a lot of modders would be very grateful to you (and it would keep this topic "on topic").

file sizes are limted by the main firmware so increasing the file size beyond the limit will only make the phone crash

so you know the limits so try this in the k550/w610 driver for 2mp low compression

900 800
#SET_JPEG_MIN(00,00) #SET_JPEG_MAX(03,84) #SET_JPEG_AVG(03,20) #SET_JPEG_QUALITY

thanks.
Raiderski or Kriomag - bigger file size (bigger than orginal) gives more quality, or we can not see this on photo by eyes?

It's really hard, or impossible, to see it. But it's cool
