This camdriver is basically an attempt to put together good features of various modded camdrivers around esato and se-nse forums, which one camdriver has but another lacks.

First of all, I am profoundly indebted to people like Raiderski, Strong, Brazzuka, ta_power, Witchking, and many others. I could learn a lot from these people’s codes.

Let me confess that I am not a modder basically, but I can understand the camdriver code. I know some assembly language as well as high-level programming languages like C and VB.

I took the “icing on the cake” of these people’s camdrivers and made this camdriver based on the original K850 v3.7 camdriver and I currently use it. So, I thought I would share with those who are interested in it. Blessings as well as curses are welcome.

Features are:
For still camera mode:
1. Forced flash in RER
2. 4 flashes instead of 3 for RER.
3. Default sharpness 7 instead of 0 for non-doc mode scenes.

For video camera mode:
1. Video size 352 x 288
2. Night mode video fps 25
3. Manual focus in video mode

To use manual focus in video mode, switch camera into night mode. Then, EV buttons (D pad up/down) work as focus keys rather than exposure.

In non-night mode, the EV buttons work as exposure control. So, if you want to control exposure in video mode, you can first set the focus in the night mode, then turn off the night mode, and then control the exposure.

Now the video is minimally pixelated and blocky. I will post some samples of video too


NB: No another application running error, focusing difficulty, or flash firing inconsistencies

AutoChrome Camdriver for K850 Version 4.0
New feature: Manual focus in photo mode

To use manual focus in photo mode:
a) switch camera into infinity focus mode.
b) Zoom in a little (1x, 2x, etc.).
c) Press EV buttons to focus in or out.
d) After the focus is set, zoom out back to zero and click the photo

So, to sum up, if you press EV buttons when zoomed in, it works as manual focus
If you press EV buttons without zooming in, it works as exposure function.

This method serves as zoom preview also like we used to have in Raiderski camdriver for K800

Note: Always use manual focus only when infinite focus is selected or in scene modes like landscape. Otherwise, manual focus will be lost when you half-press the shutter button.

Bugfix:
Previously, exposure below zeroth level (ie. -0.2 to 0) would not work (did anybody notice that??) - Now fixed.

Improvement:
Previously, sometimes exposure found to be interfering with the manual focus by sudden brightness changes while pressing EV buttons in manual focus mode - Rewrote code to avoid this inteference
