Digital camera question...
 

I'm camera illiterate so easy on all the technospeak.
I've got an old Sony DSC-S70. Junk. Takes a decent picture but is not simple to operate. My question is this... If I take a picture and try to blow it up at all after I get it downloaded, it gets grainy and pixelated almost immeadiately, regardless of which image size I use (640 all the way up to 2048).
Is this just how it is or am I overlooking something?


Jeff-

Is there a setting for different pic quality somewhere? If you have low mega pixels (like 1.0) you will get a grainy pic when enlarged. I'm not very good with "high tech stuff" either :laugh: .

Depending upon how old the camera is will directly determine how much you can blow up the photograph.

Newer digital cameras can go as high as 12 Meg :eek: for a single photograph. Needless to say, this can take a huge amount of space within the camera and on your computer. I have two digital cameras. The older one (about 4 years old) takes 2 Meg shots while the newer, compact one I have goes up to 4 Meg.

You should also check the setting on your camera as well, as most cameras have different resolutions. At low res, my 4 Meg camera can store almost 500 pictures, but at high res, only about 150 shots. Obviously, the higher res the picture is teken, the more it can be enlarged.

You should be able to find a user manual for your camera on line that will tell you how to change this setting.

Hope this helps.

Its a 3.3 mega pixel camera. Not sure about adjusting the megs? Is that not the same as adjusting the image size? Mine can go from 640 to 2048 on image size, but the larger image size still does not helpwith the problem.


Jeff-

Make sure the internal settings of the camera are set for the highest resolution it is capable of. That will be your best quality picture, regardless of size.

Next is the program you are using to "blow it up". It might be the one creating the problem. Theoretically, at 3.3 mpix you should have a very large image, you'd need to shrink it to post it on The Samba for instance. I use PictureIt! 9.0 to do my sizing and it's never had a problem. It does have settings on the side that you have to look at. One is "maintain pixel quality" or somthing like that, you want to keep that, and the original width/height ratio, but just change the overall size. So all that quality just gets shrunk down to a smaller pic, less data.

I don't know if this helps at all, lemme know if there are some more specifics you are looking for. I'm not any kinda wizard with this stuff, but I make it work OK.

change the still image size setting to 2048 x 1536 on the camera.

Thanks everybody!
Bullyboy, I tried that. Doesn't seem to help much and makes the picture huge.
I guess what I'm trying to do is outside the ability of the equip or user:rolleyes: . I just wanted to zoom in on some of the detail of some of the pictures I take, without it getting so pixelated.


Jeff-

That just means you're viewing them at something like 72 DPI
Change you picture viewer to something like 300 DPI and you'll have a smaller high definition picture. If I open the pictures from my camera at 2048x1536 they are 28"x21" at 72 DPI.
You're on the right track.:agree:
