mercury_in_flames Posted July 25, 2006 Report Share Posted July 25, 2006 I was just wondering, My olympus 5mp camera, c50 zoom; when you view the images at 100% on the computer, they are pretty grainy; see uploaded image; thats on max quality setting. Do all camera have images that have that fuzziness about them at best quality setting/max res.?http://img.photobucket.com/albums/v318/gre...er/P7250033.jpg Quote Link to comment Share on other sites More sharing options...
greenmachine Posted July 26, 2006 Report Share Posted July 26, 2006 Although i don't see the grain in this particular picture (it seems to be resized to 1.2 mpix), cameras with small sensors and lots of pixels (smaller pixel size) generally tend to produce more grain in not so well lit situations. Applying noise reduction will cause blur. Professional cameras use larger sensors. Quote Link to comment Share on other sites More sharing options...

danielbb90 Posted July 26, 2006 Report Share Posted July 26, 2006 (edited) here is the full res photo, sorry i didnt realise till u mentioned it;[broken & Fixed]Is there focus settings on it?I know on my camera you get realy grainy images with the wrong setting...(plus that 2nd links broken) Edited July 26, 2006 by danielbb90 Quote Link to comment Share on other sites More sharing options...
mercury_in_flames Posted July 26, 2006 Author Report Share Posted July 26, 2006 link fixed!! Quote Link to comment Share on other sites More sharing options...
danielbb90 Posted July 26, 2006 Report Share Posted July 26, 2006 (edited) I woulden't say thats much to worry about.. mines way worse! I think its the focus - compair some objects in that photo in the distence (like the fence - where you can see the slight grain - to something closer like the table..Does it have auto focus or is there a switch or setting somewhere?Auto focus - I think detects the center of the image Edited July 26, 2006 by danielbb90 Quote Link to comment Share on other sites More sharing options...
mercury_in_flames Posted July 26, 2006 Author Report Share Posted July 26, 2006 i dunno, i cant wait to get my new camera to compare the results with the pics my olympus takes. Quote Link to comment Share on other sites More sharing options...
KrazyIvan Posted July 27, 2006 Report Share Posted July 27, 2006 (edited) Is that at max zoom or wide angle? EDIT: Never mind. I just read a review of your camera and it appears that what you see is normal for the optics of your camera. Optical Distortion: Optical distortion on the C-50 is rather high at the wide-angle end, where I measured approximately 1.05 percent barrel distortion. The telephoto end fared much better, as I found only three pixels of barrel distortion there (about 0.1 percent). Chromatic aberration is moderately high, showing about five or six pixels of coloration on either side of the target lines. (This distortion is visible as a very slight colored fringe around the objects at the edges of the field of view on the resolution target.) With the lens at telephoto, there also seemed to be quite a bit of flare at the boundaries of the dark target elements.

mercury_in_flames Posted July 27, 2006 Author Report Share Posted July 27, 2006 which means... ?? Quote Link to comment Share on other sites More sharing options...
KrazyIvan Posted July 27, 2006 Report Share Posted July 27, 2006 which means... ?? Either the lens is dirty/scratched or it is just the nature of the optics on your camera. Quote Link to comment Share on other sites More sharing options...
streaml1ne Posted July 28, 2006 Report Share Posted July 28, 2006 Are you referring to the jagged edges of objects? If so it looks like a poor antialiasing filter in whatever image processing the Olympus does. Oh and you'll be happy with the Canon, DIGIC image processing is some of the best you can get, even in the point and shoot arena. Quote Link to comment Share on other sites More sharing options...
KrazyIvan Posted July 28, 2006 Report Share Posted July 28, 2006 If you look at the leaves on the trees you can see purple fringing. That is called chromatic abberation. SP? That is normal in a lot of cameras. Especially zoom cameras. The ones with better optics will have less of it. Quote Link to comment Share on other sites More sharing options...
Sparky191 Posted July 28, 2006 Report Share Posted July 28, 2006 Perhaps the ISO settings are wrong? I compared to some of my pics on a 3.2 Nikon 3700, which is a couple of years old now, and I would say your pic is a little bit noiser than mine. Experiment with ther setting, perhaps some of the other modes are less noisy. Quote Link to comment Share on other sites More sharing options...
mercury_in_flames Posted July 28, 2006 Author Report Share Posted July 28, 2006 the highest it goes up to is about 300. could that be it? Quote Link to comment Share on other sites More sharing options...
Sparky191 Posted July 28, 2006 Report Share Posted July 28, 2006 Try it on its highest setting and see how it looks. The lowest settings will be noiser. Not that I know much about it. Quote Link to comment Share on other sites More sharing options...
KrazyIvan Posted July 28, 2006 Report Share Posted July 28, 2006 (edited) It is usually the other way around. High ISO's are noisier. Heat can also make an image nosier. If you are using the LCD screen to frame your pics switch to the viewfinder. The LCD actually heats up the back of your CMOS/CCD sensor and causes noise to appear in your pictures. It can also happen if your camera is just hot in general. Edited July 28, 2006 by KrazyIvan Quote Link to comment Share on other sites More sharing options...
