How big should pics come out?

[cpgoose]

Hello....curious if anyone has an answer/opinion on this....

I have an Olympus Stylus 410 (4 megapixels). When I take pictures on the highest setting (SHQ), they only come out about 2.5 megs maximum, I can't really get more than that. Someone else was telling me their 5 mg camera takes pictures just below 5 mgs. Should my camera be taking larger pictures, or is this it? They're coming out 2272 x 1704.

Any ideas?

Thanks!

2272x1704 sounds about right. The marketing is not always exact.

Mines a 3MP they come out about the same size as yours.

File size depends on a lot of factors, compression being one. Jpegs can be compressed more if you so desire so the resolution really has no affect on it. Additionally the content of the picture can also affect the filesize. Take a picture of soemthing that is one color and you'll see a significant decrese in filesize.

2.5MB sounds about right for a 4 MP camera though.

About or the same? There is really not that big of difference. Hell, my 5 megapixel camera is 2560x1920.

Your camera is probably using less compression, my GF's 3.2 MP was right in the 2-2.2MB area.

Mine at 2048x1535 comes out at 1.4mb but can also get the same size,At 554kb.Quality is bad though.

Hmmm....I guess I never really questioned it until this guy did. Strange that his are coming out almost 5megs with a 5-meg camera. Maybe SLRs (if that's what his is) are different?

You mean a MB per MP?

Again biggest factor is the compression level, that would be your quality setting. A Digital SLR will offer more settings, probably as high as 100% quality which would be comaparable to a lossless AVI Codec.

Here's 90% quality, 37K:



75% quality, 22k




50% 17k



You'd be hard pressed to find much difference between the first two without zooming. Printing them may show the differences a little better. If you comapre the first and the last one you can see there's been quite a bit of detail lost.

I think the megapixel works in "total" number and "effective" number of pixels. Meaning the total is the size of the sensor when it captures and the effective is what the camera stores in memory.
Here's and example of my camera...Total number of pixels: Approx 3.34 million/Effective number of pixels: Approx. 3.2 million
BTW that camera seems to very good with compression. My canon is 3Mp and they average about 2Megs each.

Thanks for all of the replies!

Yea, I guess I was confusing MP and MB a bit, too. Mine is a 4MP, and the pics are coming out around 2.5 MB, so that seems about right judging by your responses.

Thanks again!
