I was wondering if the mb size of the photo matters ?
Some roms I get pictures that are up to 2.0 mb. Some don't even reach 1.0 mb
And also some roms record in AVI (Unity Rom)
Some record in 3gp.
Do these formats / size matter in the quality ?

Yes, compression ratio in photos matters to quality. But - small differences in compression can lead to large differences in file sizes, but those small differences might be barely visible to the eye. So there's no clear answer, and "more GBs" doesn't necessarily equal better photos.

As it was possible for the nexus one, im wondering if it maybe will be possible for the tab when you are enable to flash it?
And one question to is, is the video recording any good? and is there any software to make the resolution higher when you watch it? i one if you convert the quality wont be beter but if will be the same but on bigger screens?
regards
The Nexus had a 5mp where as this has 3mp. I wouldnt exactly say the Nexus had HD recording, IMHO, the image was just a bit sharper and more of a makeshift HD.
Would it even be possible to record HD with 3mp?

it should be.. 1920x1080 is just over 2mp
Im sure record and playback will get much better once we have a good custom kernel to flash.

For recording the sensor needs to be able to push whatever you're recording at a decent number of frames/sec though and if the hardware doesn't cope with it, then you don't really get a much better image than you would than simply resizing the existing video to the same size. It's mostly a waste of time on the N1 as the quality is quite poor regardless of the resolution, I suspect it'd be even more so on the Tab.
Sometimes you just need better quality optics and/or sensors, software can't always substitute the hardware.
I know this seems like a question - but i just read on Engadget that NODO-GT was able to modify the camera to shoot 20mb and 0 compression.
I know the Galaxy SII has an 8 mp. But is it modifiable to reduce compression as well?

intresting
Hmmmmm. could be.
there's many hidden features in stock framework are not implemented.
video recording pause for example.
HTC stock camera contains a lot of conpression due to HTC Sense camera enhancement mode. Thats why disabling it to total zero would give out the best RAW image out of it so you can alter the pic yourself without the dirty software auto correction
Im not sure bout SGS2, seems like not many devs are interested in the camera part for SGS2. They keen towards audio more but not much progress has been made throughout the year

True - thought I think be devs - you mean Supercurio. I'm not really aware of anyone else.
I saw one Dev that did camera but for video recording (and sound). It would really be great to be able to fine-tune the camera for better quality and performance!
A couple of reviews have remarked on the uncomfortably high level of JPEG compression they saw on HTC One photos, and said that there's no way to turn the compression down. They were most likely using phones with pre-release software, and normally I wouldn't be too concerned at this stage, as that's the kind of thing that would likely be tweaked later; but in this case I have to wonder whether high levels of compression is a "feature" that HTC judged to be absolutely necessary because of the Zoe system. With Zoe turned on, every time you take a picture you're actually capturing twenty separate 4-megapixel images, plus a 3-second-long 1080p video clip as well: turn the compression down and your 26GB would fill up very quickly.
Does anyone have any first-hand knowledge of whether this is an issue in final software? And, if it is, does anyone have any educated speculation as to whether it might be possible to work around it without voiding your warranty?
A final observation: I wonder if some of the complaints about supposed "noise" in certain HTC One photos may actually be referring to compression artefacts?
heavy compression is indeed worrying on the One X we have camera mods which can fix this but needed root
As per i have read htc one doesnt use any compression and if in certain cases it does its very less..

no during processing it does it over RAW images using its imagesense chipset but the end results when saving to the Nand is still getting compressed
Forgive my ignorance but why would the compression be a bad thing as it will reduce space but I assume reduce the quality of the photo?

JPEG reduces the size and quality
I think it was the Polish review where the guy mentions that there was no way of changing the jpeg compression settings. Perhaps the default is set to medium rather than high which could explain the artifacts?

So I suppose it would depend on how much the quality reduces as to whether it's going to be that bad of a thing compared to the room on the SD Card that is saved?
Could a mod be made to unlock the compression for those that don't want it?

Is someone going to answer this question ... I could, but not in the next 12 hours or so .. and it IS an important question .. somebody please post a close-up of a heavily compressed jpeg vs a tiff or raw ...
otherwise I'll be back to answer I guess

Dude...?
What are the disadvantages of lowering camera resolution (shooting at non native resolution)? For example from 16 MP to 8 MP.
The resolution and file size would obviously be smaller but would it reduce quality of photos as well? Would it be better if I taken photos at native resolution and then resize them with some software?

The file size will be smaller and the resolution will be smaller. You wouldn't notice any quality reduction at all. Why not just shoot at 16mp and crop it to your likings anyways? Thats a better option.

Indeed, unless there comes some pixel bind mod there is no real benefit apart from the smaller file size.
Although saying that I ain't that bothered anyway. Have my proper cameras for important pictures, phone is for make do snaps
Shouldn't taking/saving pics be faster when lower resolution is selected?
more megapixels means more details (but when you zoom)
if you want to see photos on phone or regular TV or laptop (without zoom) , there are no difference between 16 or 8 or even 6 megapixel
but if you want to zoom or see on a large screen (cinema!!!) you can see difference

This.... People with their questions.... As if they came from the moon.
Is there any way to decrease jpeg quality to some reasonable levels?
Right now my camera is set to 16 Mpx widescreen and takes 9-10 MB large files.
I have edited one of the pictures in photoshop (just loaded and saved as jpeg again) but with reduced jpeg quality - set ot 7 out of 12 levels.
There were no visible differences of the pictures BUT the new file was 3 MB !
I think that default settings for jpeg compression is set too high in camera app. How to alter this ?
Of course a 3mb file will still look good. It just depends on what you are viewing pictures on. If it is a phone or average hd screen of a smaller size then at face value telling a difference is not easy.
If you blow the two photos up to a huge size, then the differences will show.
The reality is for basic device use we don't need all the megapixels we currently have. Better sensors however is a different story....

I'm viewing images on my PC. I have 27" 2560x1440 monitor, and I cannot tell the difference
