I asked this before, didn't get an answer. The pics I take with my iPhone4 are 2.2-2.6M. They used to be around 1M on iPhone 3GS.

That's why too much. The same quality can be achieved with 500K. The rest is a waste of pixels (and storage).

Just curious, anyone knows why Apple is so stubborn and does not want to give the user any choice.

macbook pro 2007, Mac OS X (10.6.4), iPhone 3GS and 4, iOS4

    hey use "photo scape"-win application; n save with quality setting to low
    ull have the same picture with decreased size

    dude plz help me no ones,replying to my post

    The new iPhone has a better camera and takes better resolution pictures. You don't get the same quality at 500kb as you do at 2mb unless you only like postage stamp size pictures.

    Well, DUH!!!! The iPhone 4 has a 5 megapixel camera, the 3GS had 3 megapixels. Where do you expect the 2 extra megapixels to go?

    The same quality can be achieved with 500K.

    It absolutely cannot be. Jpeg is "lossy" compression. The smaller you make it the lower the quality. As it is a raw 5 megapixel image requires 12 MB. At 2 MB it has already been heavily compressed. If you really want lower resolution you can edit the photo on your computer with any photo editor and reduce the resolution (and quality) to any size you want.

    You have a choice. Get a cheap camera. Or edit the photo after taking it. You can always reduce quality after the photo is taken, but you cannot increase it if the resolution isn't there to start with.

    Yes, I currently compress them

    I know that, my point is megapixel is not all. My dedicated digital camera takes much better 500k pictures. Say I am looking at a small detail in the picture. What's the point of storing 100 pixels if they are all the identical? On the other hand my digital camera stores only 20 pixels, but they are different! All I am saying is given the iphone camera/lens, 2.6M is a waste.

    See my reply to Tamara.

    You have a point about the relative quality of photos taken with a dedicated camera vs a cell phone camera (ANY cell phone camera). The fact is that the lens on a cell phone camera is too small, and the sensor is too small to take high quality pictures. In reality there is no point in pairing a tiny 5 mp sensor with such a low quality lens. A 2 mp camera would take almost as good pictures. But the iPhone was universally criticized when it came out because it had only a 2 mp camera. So Apple bowed to market pressure and put a 5 mp sensor behind a lens that could not take photos better than a 2 mp camera because of the lens size and quality. But a consequence of the 5 mp sensor is large files. There isn't a lot that can be done about that in the camera itself; it requires post processing to compress the file further. And if the camera app took the time to post process photos then people would complain that the camera was too slow.

    You answered my question - the post-processing would be too slow (it's a computation intensive task after all), that's I don't have the option to reduce the size. (It would also consumes extra power I think).
    Thanks,
