Video recording still has zoom bug, stop delay...
can you tell me where is the line to set default FPS? And the value of the default fps... |

this photo's was taken with 3.3 mod when i was driving with 60km/h today.
1. camera setted to sport
2. camera setted to automode
The second pic it's a little bit shaked.....

I agree with you bjorndan, digital zoom is pointless. I never use in my k790 or my Canon Powershot SD1000. It's optical or nothing at all. I couldn't care less for that zoom video bug the 25fps tweak makes up for it.

Ok guys, look we need some strong modders for k800/810... I made this mods with minimum changes bucause i don't know what else can i do, so my mods stops here. From know on just learnig from my self and from others modders how to mod a big things. So, we need help in this topic from other modders...
i'm not a programmer, i'm not SE expert, i'm not computer tech, i'm not nothing! i'm a ordinary man just like you. (well a little bit curious)
I think noones care about this phones k790/k800/k810 but i've made the start...
Thanks!  |

So do I. I never use it either. But the issue here is to inform the modder that the camdriver still have a bug :)

pointless fopr still photography, but useful for video. Check my video links if you don't believe it - due to the graininess of 3gp video anyway, the digital zoom pixelation is hardly noticable when you zoom in with digital zoom.
The zoomed video is actually quite watchable, and gives better detail than the non-zoomed version.
Here's some video captures to demonstrate:

actually, it is all digital cameras (all sensors, but especially cmos) that suffers from noise problems. It's inherrant to the nature of digital camera technology. No matter what the camera, you will always get an increase in noise with an increase in ISO. It's EXACTLY the same scenario with film. Higher ISO = more graininess.
However, the better quality the sensor, the less noise you get. Just like the better quality film you use, the less graininess at high iso's. It's not the size per se, though smaller sensors are harder to make at high quality, so CHEAP sensors are always small and crap. However, as technology improves, it becomes possible to make smaller and smaller sensors for the same quality (ie: low noise). So you can have smaller sensors, but if you want the same quality, the sensor will be much more expensive.
Yes and no. Size do matter. My dSLR is creating almost noise free up to ISO800. Even, I can make ISO3200 that I shoot in my 3 year old dSLR looks comparable to K800 shoot at daylight in term of noise. Yes I do use noise ninja to do that but so do K800 (in the firmware implementation).
The higher the ISO the more noise is because the sensor applied more gained to the signal and that create more noise.
The more MP the smaller the pitch in the sensor that responsible for getting the light. The smaller the pitch, the more noise it generate when it tries to 'boost' the signal, especially if you use higher ISO (higher gain). That is for the same size and same technology.
You can improve noise by using bigger sensor size if you want to stay at same mp. If the mp is same then you enlarge the pitch size by using bigger size.
I agree that over time technology will improve and we can see lower noise than the older technology. But bigger pitch in sensor will always get lower noise at any given (same) technology level. It is the same like we all will fall down because of gravity. Yes we can always make better sensor. But if you make 2 sensor size with same MP using the same technology then the bigger always win in term of noise at any given ISO, due to bigger pitch.
See that new Nikon D3, it can shoot at ISO25600 (Yes that number is correct) because it is only 12mp in FF (film) size sensor. The Nikon D300 and Sony A700 with same 12mp but APS-C smaller sensor can only achieve ISO6400.

I'm not saying that size doesn't matter, I'm just saying it's not fixed. The size is dependent on technology, not on some fixed everlasting ratio of noise to sensor size. People are getting hung up on sensor size. The issue is, on a camera phone the sensor is always going to be small. Sensors are not going to get bigger (much) so new camera phones can only increase in quality by improving the sensor technolgoy for small cheap sensors, not by using larger sensors.
People have said you will never get good iso performance on a small sensor. I disagree implicitly. Each year manufacturing methods get better and better. Soon noise from high iso's will be far less of a problem for camera phones, just as it was once a problem for low end dedicated digital cameras, but now is only a problem in the real ultra cheapies.
People can use the small chip/low quality argument as much as they like, but the fact is only in large professional digital cameras is there the space to make sensors bigger rather than smaller. On consumer digital cameras sensors are getting smaller but giving the same quality and increasing in MP capacity all the time. This is no different for camera phones.

so max... are you using the stock drivers?! or the modded ones...
which modded ones just incase.

stock. No advantages in any of the modded ones. Actually I have mongooses modded 2MP driver for testing, but the 3MP section is stock.

Guys, I notice some complaining about extra noise when ISO is at 400. If you want to use a larger ISO setting get used to it, there's nothing you can do - especially in low light. All digicams suffer increased noise as ISO increases, especially camera's with small lens. Read up on ISO if you want to understand why.
Has anyone really been happy with any of the mods they've done? About the only mod that makes any real difference is playing with the sharpness setting. I think increasing the sharpness makes for less natural looking images and is not suitable for everyday shots. Increased sharpness seems best used for macro shots - in which case you can use document mode.
Everyone's got their own personal preferences - that's mine.
I have not noticed any great difference by using 95-100% compression. And, It really doesn't make any sense to me why photo's get smaller in file size as you decrease the amount of compression used. I'm struggling to see what the difference is in the 2mp photos when the buffer size is set to 900kb. All I see is a bigger file.
For now I have reverted back to orig cam driver as I would rather reliability over tweaks that offer very little improvement. Most imprtantly, it seems there is no way address the lack of anti-aliasing in this camera. This comes down to firmware/hardware. But, the more I look around the more I see that other camera phones suffer the same issue - although not quite as badly or frequently as the K800.
Lastly, if you guys what to be a little more adventurous I reckon you could write you own macros to set various sharpness settings. It shouldn't be too hard. In the orig driver all you have is a Normal and Document macro used to set EV and sharpness. So you could get the scenes (property 16 of the drive to use different settings if you like by calling dife
DING!
I'm glad that the modding community is experimenting with different settings within the camera driver. However, the extra sharpness and colour differences don't justify losing the naturalness that the original driver brings. Don't take this to offense. In fact, I urge people to further experiment. However, I still believe that the original driver + Photoshop is the way to go. |

I think I'll have to go back to stock drivers too. These modded ones are way too sharp. They are good for night photos but day pics, especially with lots of sunlight are terribly over sharpened.
What I really liked is the 25fps video tweak. Are there stock camera drivers with just the 25fps tweak applied. That'd be what I need, actually. thank you...

@Xan K
about the over sharpening in daylight photos can be compensated by adjusting your EV values to negative... have try that?!
