I also miss it sometimes.




yeah, you're right, we have just 13 placeholders. you can change them though, values are from 32 (20 hex) to 0(infinity).




with original camdriver, minimum shutter speed is 1/2sec, but we can get slower shutter speeds, the problem is that it'll be grainy, it's noise, so i fixed ISO to 100 in manual shutter speed, but still it's noisy. 1.7 is 1sec and 2.0 is 2sec (in twilight scenes). slower shutter speed = more noise


some links about noise and noise-reduction:

Image noise
Noise reduction
Reducing Noise using GIMP
Dark frame subtraction

(although these are about CCD, these can be applied to CMOS too)

thanks for the great camdriver..

but, when i play with shutter speed, suddenly my camera will become so slow, even after i enter the default shutter speed and/or setting the lowest shutter speed (1/5000 i believe). even after i close and reopen again the cybershot.

luckyly, this could be repaired by changing the camdriver with others, then put it again inside the phone.

but i worried.. does this could damage the camera itself (hardware)


sorry for my stupidity in english language. i'm no native english

ps: i'll really like to ur camdriver since ver A

Thank you.




That's weird. i didn't face such problem, so i don't know the reason, it may damage the camera, probably version B is better for you.

Here you can download the driver.

there is a bug though, you can't change EV in normal focus mode, if you want to use normal auto focus, for changing EV go to macro, change EV and then back to normal.

When you open the camera and set manual settings to EV, it'll control both shutter speed and ISO. when you change ISO and then back to EV, it'll control shutter speed. when you change shutter speed and then back to EV, it'll control ISO.

sometimes there is a limit, for example if you open the camera in a dark room, set settings to EV and scenes to twilight landscape, then camera will choose 1/2sec shutter speed and ISO100, now if you change EV to -2.0, shutter speed and ISO will remain the same.


This is my current camdriver, i only changed color correction to sharpness.

Here is a free tool for dark frame subtraction: blackframe by Mediachance

link to the webpage


example: 1sec exposure with K550i@W610i :



original pic
dark frame
result


note1: take dark frame pic with exactly same settings that you took actual pic
note2: use this method just for shutter speed > 1/2sec
