Oh, I'll just copy and paste the text here... It's a lot of it, but it should be useful to you:
Instructions for SPU's driver:
First of all, most default settings can be changed in the config section of the driver (there are some comments).
I'll skip the list of standard settings in my driver like contrast, sharpening, focus modes, zoom algorithm and so on, i'll provide only the description of special features, but only one thing:
JPEG quality for General mode (or whatever in english menu?) is set to 85% (which is High in original dirver) and 92% for High quality mode. So if you in some cases got driver failures, select General quality and forgot about failures.
Note: This driver works without any restrictions and problems on any compatible phone (750/800/810) with any version of cam module. There is only zoom restrictions in new cam modules, but this is not a big trouble.
Normal mode (i.e. not in supermode):
(the following works also in supermode)
1. Zoom keys
Manual focus in foto mode (1.0 autofocus, 1.1 - infinity, 1.2 - 4.0 from about 5 meters to 8.5 cm) and zoom in video mode.
You can use Macro key to turn on/off 4x zoom in manual focus range (1.1 - 4.0).
2. Effects menu
off - normal WB + centerwighted photometry
BW - one push WB + centerwighted photometry
negative - normal WB + spot photometry
sepia - one push WB + spot photometry
solarize - change menu functionality to standart (effects) and back
This setting stored in phone memory so you can turn camera off and on whitout resetting the mode combination.
3. WB lock and AE lock
You can turn on and off WB lock by the sequence <><> (starting from EV 0.0).
You can turn on and off AE lock by the sequence ><>< (starting from EV 0.0).
All WB adjustments (WB preset or mode via Effects menu) ingnored when WB lock is active, but new settings will be applied after WB unlock.
4. Different autocorrections
a. autoselected (by the camera version) color profile (color adjustments for every WB preset)
b. EV autocorrection for every camera mode (normal/night, with/without LED), by default it adds some underexposure.
c. color correction to compensate LED flash specifics (depends on distance to the object).
Note the difference with other drivers: all corrections active only during shoting process, so them does not change (mess up) standard automatics behavior at all.
Supermode:
You can enter on leave supermode with the sequence <<**>> (starting from EV 0.0).
Leaving supermode will reset all camera settings to the default state.
Supermode tables slightly depends on the current mode (foto/video):
In any row Zoom 1.0 corresponds to the auto or the default setting.
Foto:
-2.0 JPEG quality (1.0 default, 1.1-4.0 - 40%-98%)
-1.7 brightness
-1.3 contrast
-1.0 shutter speed (normal + night mode)
-0.7 ISO ( 1.0 - auto, 1.1 - 100, 1.2 - 125, 1.3 - 160, 1.4 - 200, 1.5 - 250, 1.6 - 320, 1.7 - 400, 1.8 - 500, 1.9 - 640, 2.0 - 800,
2.1 - 1000, 2.2 - 1250, 2.3 - 1600, 2.4 - 4.0 - undefined. )
-0.3 Zoom
0.0 manual focus
+0.3 EV
+0.7 manual WB. tint. green. (1.0 neutral - 4.0 green)
+1.0 manual WB. tint. magenta. (1.0 neutral - 4.0 magenta)
+1.3 manual WB. temperature. yellow. (1.0 neutral - 4.0 yellow)
+1.7 manual WB. temperature. blue. (1.0 neutral - 4.0 blue)
+2.0 saturation
Video:
-2.0 JPEG quality (1.0 default, 1.1-4.0 - 40%-98%)
-1.7 brightness
-1.3 contrast
-1.0 FPS
-0.7 ISO
-0.3 manual focus
0.0 Zoom
+0.3 EV
+0.7 manual WB. tint. green. (1.0 neutral - 4.0 green)
+1.0 manual WB. tint. magenta. (1.0 neutral - 4.0 magenta)
+1.3 manual WB. temperature. yellow. (1.0 neutral - 4.0 yellow)
+1.7 manual WB. temperature. blue. (1.0 neutral - 4.0 blue)
+2.0 saturation
Note that in manual WB only one color in group (tint, temperature) can be adjusted, because green/magenta (and yellow/blue) is in one "color space".
There are more complicated dependencies between manual WB, color profile, LED color adjustments and so on, but it's hard to describe everything at once =)
1. If you want to take a picture of something that lays beyond 4-5 meters "line" (landscape for example) it's better to set manual focus into infinity (zoom 1.1)
2. Try different WB presets. Often their name is not directly connected with the environment. For example, for shooting with LED in the room with tungsten light it's better to set Fluorescent WB and so on.
3. If you need to properly exposure something relatively small (to the whole picture). For example face on the portrait or the sun in the clouds. You need to switch from centerweighted photometry to the spot photometry.
4. If you whant to reduce "noice" on the picture, you need to turn on supermode and set the ISO to 100, then you may need to adjust the shutter speed.
5. If you totally don't like the WB work (wrong colors) in some place, select Auto WB, then turn on One Push WB via the effects menu, point your camera to something white (or grey) and wait a bit until the color on the screen became really white (or grey), then make the WB lock. Now you can make a picts with true colors in this place. Don't forget to unlock the WB and return to normal WB via Effects menu after all =)
6. If you want to take a series of a picts with the same exposure (for panorama for example), just turn on the AE lock.
ver. 1.3-b2:
Changes:
1. In supermode there is saturation instead of scenes (EV +2.0). Zoom 1.0 - default, 1.1 - desaturated (BW) - 4.0 very saturated.
2. By the default driver makes a pictures a little bit more saturated. You can change this in config via DF_SATURATION (this must be 00 if you want to get the default saturation of the original driver).
New beta: 1.3 beta 3
There was a lot of small changes since the first release of beta 2, so i can't remember all of them.
Today changes (since latest update of beta 2):
1. In SM shutter speed (EV -1.0) now have an auto state in night mode, so the table of zoom looks like this:
normal mode: 1.0 - auto, 1.1 - 6400, ... , 4.0 - 6
night mode: 1.0 - auto, 1.1 - 5, ... , 2.0 - 0.5 (2.1 - 4.0 - also 0.5)
2. When AE lock is on, it restores himself after shutter speed or ISO changes. So with AE lock you can set for example ISO 100 and exposure time 2 seconds in any light conditions.
3. Drivers auto EV correction is disabled when shutter speed and/or ISO are in manual state. So "what you set is what you get", if camera automatics does not change the settings due some built in limitations.

" can you please explain this further? i don't understand how this works. when i locked AE and increased shutter speed (EV -1.0, zoom keys 1., the 3rd shot below was obtained at iso 80!"
I'll try to explain =)
First of all: any changes of shutter speed or ISO unsets AE lock.
Second: when you set manual shutter speed (ISO is Auto) you get shutter speed priority and camera automatically adjusts the ISO but step by step (this is very important!).
Third: when you set manual ISO you get an ISO priority but this resets shutter speed (in any case) to the default value.
And the last: when AE lock is on it will be restored after every change of shutter speed or ISO.
Conclusion: Turn on the AE lock, set ISO as you want and than shutter speed you'll get exactly this ISO and shutter speed (if they are not exeeds the hardware limits).
PS: I don't know yet how to set ISO 80 manually, but you can get it changing only shutter speed as you already done =)

1.3 beta 5
Now Fine mode is an adaptive compression mode (as it was in beta 4), but Normal mode is a "classic" mode with a "fixed" quality.
In real life Fine mode can't cause any problems, but if you like to experiment with totally overexposured pictures you can catch a crash or extremally low quality (0%). In that case you can switch to the Normal mode and get what you want.
Default settings:
Normal mode (quality based): 85%
Fine mode (size based):
1632?1224 - 550 (+-50) KB
640x480 - 100 (+-25) KB
160x120 - 15 (+-10) KB
All this settings can be changed in the driver config section.
1.3 beta 6
A small technical update: now sharpening is set automatically.
By default: 05 for new camera modules and 06 for old ones.
If you need you can change this setting in the driver config section (you can set DF_SHARPENING to the real value or to the predefined macro #SP_CID36, #SP_CID49, #SP_AUTO).

1.3 beta 7
New camera modules can't understant positive values of saturation, so in this version saturation is set automatically (00 for k750 CID 49, and 06 for w810/w800 and k750 cid36). And now in SM saturation for new camera modules works in different way: Zoom 1.0 - default, Zoom 1.1: -3 ... Zoom 4.0: -32 (B/W).

1.3 beta 8
1. Disabled bilinear filtering for 1632x1224 resolution (sharper image)
2. Normal focus now 00 instead of 01.
3. Introduced frameskipping settings for video modes in config
4. MXE sync settings restored (not tested)
Posted: 2007-06-24 22:34
1.3 beta 9
Changes:
1. Bilinear filter is disabled for Normal mode and enabled for Night mode by default.
2. No more "dead" JPEGs on very slow shutter speeds (driver uses Normal (classic) compession algorithm in this case).
