That's why I'm decreasing the sharpening on kopritis 2.8 camdriver, cause if I make it lower the jaggies going low, but so far very subjective to judge which setting is \"balanced\" for individual, so try yourself for sharpening setting, but for me 03 is the balanced setting (which is give 37.5% sharpening).

Take a shot in draft mode, the flash activates, but the pic gets underexposed, despite this, the picture looks great, you can see it after applyin photo dj light balance filter. That is the line we gotta follow

yep, I set the flash to 100 in the driver (instead of 400 ISO) and got the same results.

Draft mode does the same thing (document setting iso = 100)

Set it to ISO 200 is better, little bit grainy, but all is Ok, other is set ISO 100 and set EV to 1.

so ISO 200 isn't too badly under-exposed? 100 was way dark, I thought of trying 200, but hadn't got around to it yet..

but if its a bit grainy... id rather stick to the stock driver...

bit grainy compared to 100 ISO that we havebeen experimenting with, but not grainy compared to the default 400 ISO (the iso that flas pics use)

Improvement found:

It's early stages at the moment (i'm still testing) but I think I have been able to make an improvement that goes a long way to reducing the jagged edges. Firstly, I must explain something to everyone - I think the there is an upper limit of 900kb for the max file size that the actual image creation software in the F/W can handle. I've come to this conclusion because no matter how hard I try I can not get any setting of much more than 900kb to work reliably and not crash the camera S/W. So, I've decided to give up on the 3mp images as I think they are a lost cause and start playing around with the 2mp image settings instead.

I've always thought the K800's 3mp images were no better than it's 2mp images. If I can produce 2mp images that are superior to the 3mp images I will be happy. So, I thought, why not apply the file size settings for 3mp images to the 2mp image settings. You know what, it works. I am now getting 2mp images that are 700-800kb in size. So far the camera has not crashed once and the images are definately clearer than the 3mp images. I've been taking direct comparison shots and asked work collegues for their opinion and they agree. I would post samples but I don't have the ability to submit images from work. And, as image quality is a personal thing I would suggest people do their own testing. So far, I've done around 10 comparison shots and each one of the 2mp images has far less jagged effect than the 3mp image. I've also done a couple of comparisons with a W810 and my K800 is now a clear winner in 2mp mode.

Max, I think also think the images with these settings amy improve the water colour effect you've noticed because the outlines are smoother. I'd like to know what you think.

I've still got some testing to do and I haven't tested 95% compression yet.

If you want to experiment further just replace the 2mp settings in your camera driver with the following:

seq_set_prop_5_6 = $"2M_High_comp"
#SET_REG(19,4B) // JPEG_INIT_QUALITY = 0x4B = 75d
#SET_REG(13,20) #SET_REG(14,03)
#SET_REG(17,58) #SET_REG(18,02)
#SET_REG(15,90) #SET_REG(16,01);

seq_set_prop_5_7 = $"2M_low_comp"
#SET_REG(19,5A) // JPEG_INIT_QUALITY = 0x5A = 90d
#SET_REG(13,84) #SET_REG(14,03)
#SET_REG(17,20) #SET_REG(18,03)
#SET_REG(15,58) #SET_REG(16,02);


I'd really like to know what others think.

@mongoose

im no techie and no modder but its laid out on plain english.. as long as i can improve something with the stock driver id gladly agree...

but man! promise me that the settings on 3mp will stay as of the stock default.
coz right now im very happy with my K810 3mp stock driver...
havent played with 2mp.. but with your driver.. its worth the wait.

i congratulate you in advance for seeking beyond what others thought theyve seen..

The settings i posted will not alter your 3mp settings. All they do is change the max, target and min file size for the 2 mp setting. When you edit the camera driver just scroll down to the 2mp settings your self - look for "seq_set_prop_5_6 = $"2M_High_comp". When you look at it it is quite self explanitory. The values are in hex. So for example the default max file size for 2mp high comp is 600. 600 in Hex is 258. For some reason the driver breaks that up to in to 2 seperate values working backwards. i.e. 58 and 02. Make sense? So to change to max size to 900 you convert 900 to Hex, which is 384. You then break that down to two values of 84 and 03 and change the setting accordingly - "#SET_REG(13,84) #SET_REG(14,03)" I hope that helps if you want to manually change the setting. Alternatively, you could make it easier and cut and paste what I provided straight over the top of the original 2mp settings.

Provided you are comfortable with FAR or XS++ this is a very safe thing to do as there are so many copies of the original camera driver floating around that you can always download it and copy it back to your phone if you really screw up the driver. I wouldn't be experimenting if I didn't have the original driver to put back in place. I've had to put the original back in place many times.
