I have received many comments that my pictures show pixelation or graininess, and I'm not sure why this happening or what I do to get rid of it.

I am using a low end camera, Sony Mavica 73FD. It's highest picture resolution is 640x480. Is this the cause?


Now don't tell me to go get a better camera, 'cause I can't afford that! Is there anything that I can do either while taking the pics or after to compensate for this?

Thanks for any help or advice anyone can give.

It is more than likely your camera. My camera has 4.1 million-pixels and I run into that problem of pixelation or graininess on longer distance shots, so I just resize the images down to do away with that. Close-up shots seemed to be okay. Try closer shots and do the best with what you got, for you are the one to please.

Despeckle is one of the allowed filters, and it can sometimes help.

I used to use a FD-73 myself, and I'm wondering if the shot you are talking about is at night or in a very lowlight situation? That is when I would run into my problems--in darker situations. It seemed to do fine when there was plenty of light.

I own the same camera, and it can be very challenging to work with. You CAN take good pictures with it, though. Some general rules i've found with it:

To fit images on the floppy disk, it tends to heavily compress images. Pictures with things like leaves, lots of different colored detail, etc, will come out rotten. So keep pictures you take with it, simple.
You can take a good picture with just about any camera, if you keep at it. Two of my personal favorites:

//nand.net/~lennier/digicam/artsy/tn/sunclouds.jpg.html
//nand.net/~lennier/digicam/places/zoo/tn/mvc-458f.jpg.html

You might want to try shooting in BMP mode. This might compensate for the heavy compression. I never could notice much difference, but you might.

Mom, I just reviewed four of your shots and you did Great with that little camera. I rated them high except the Cupola (4). I didn't like the distracting wires.

I'd agree, I think you are doing a good job with the camera. I certainly couldn't see anything too excessive in terms of noise/ grain/ pixelation. Sure it isn't as 'perfect' as a Nikon 1D or something outrageously expensive, but the pictures seem resonable. Certainly brightly lit/ daylight type subjects will do well and you are more limited in macro options and stuff but its good enough to compete with other posters here.
