Pixel count and compression settings
Nov 20, 2011 10:46:16 #
I think I understand that the pixel number is a direct relation to the size of the picture, more pixels = larger picture. Is this the same as the compression setting?
My camera has 6 pixel settings and 3 compression settings.
Can anyone help me understand this?
Thank You

Yes. In most cases, the best thing to do is use the largest or finest or biggest setting on your camera for storing the images, and the LEAST amount of compression. It's always easy to reduce an image's size, but you can not always make it bigger without losing quality.
If your memory card restrains you, get a larger capacity card.
There is no good reason to use the smaller/less quality settings on your camera.
If you tell us what your settings are, we can give exact recommendations.

My camera is a Canon PowerShot S5 IS and my choices for recording pixels go from 3264 X 2248 to 640 X 480
My compression choices are Super Fine, Fine, and Normal

Use 3264x2248, and SUPER FINE. That will give you the best quality images to start with.
As I said, it's always easy to make an image smaller. It's tough to make it bigger.

Thank You, I have an 8gb card so that should do for now. Boy this is sure different than when I was taking film pictures with my old Minolta SLR, but it looks to be more fun!

Yes - remember, digital is cheap - take as many pics as you think you might want/need, and just trash the junk. Don't waste time and opportunity thinking, "Oh gosh, I only have 24 exposures on this roll...."...Thank You, I have an 8gb card so that should do for now.

That 8 Gb card should give you over 2000 images at the highest, superfine setting. I'm sure you'll be dumping to your computer way before then, even if you go on vacation for a couple of weeks.
A word of advice from a pro friend of mine, though. Keep a spare, formatted card in a plastic case just to cover Murphy's Law, and test it to verify that it works before putting away. No reason this can't be a smaller card, say 4Gb.
I use Sandisk, have never had a card-related issue.

I tell every one who has a camera to buy two chips. When one fails not if, you'll have back up. One in the camera and one in the computer is normal behavior for most people. Lets see a 4G card will cost you less then $10.00 so cost is NOT an issue here. I've owned a computer for over 25 years. We use to say copy that floppy. It applys today as well.

Just to give an idea of how many images one can shoot in a day, 6 of us (cigar-smoking photography buffs, including one 70+ year old pro) went on a 3 day photo safari in southern Virginia and the Blue Ridge Parkway.
Once we got to the general area we were interested in, it was stop and go, shooting as we went. We shot for almost 2 straight days from daylight to near dark. At the end, the pro had the most shots, about 450. We were worn out and glad to go home (all but one of us are over 60).
If one can sustain that kind of concentrated shooting schedule with an average of 200 shots per day, it would take 20 days to use up 4000 images.
I would say a 4000 image capability will more than cover a vacation away from home.

That brings to mind a question; has anyone run up against an almost full card slowing down as it nears capacity?

I filled an 8GB SanDisk Extreme UDMA card and didn't notice any real slowdown. It just stopped saving pictures. Don't remember if I got a message from the Camera or not.

phcaan - and anyone else -
I have a Canon PowerShot 35 IS. Where on/in your camera do you find where to set it to recording pixels from 3264 X 2248 to 640 X 480 ?

I shoot RAW (nikon d300) and my card fills fast.. I suggest that after emptying the pics from your card is to reformat it simply to remove any misc info left on the card, thus a fresh one each time you shoot. You may want to ck out Perfect Resize 7 from Onone softwear The program will resize all the pixels upward for larger prints.

I always reformat after dumping to the computer. My Windows reformat works perfectly.
