Hi friends, please help me understand the following pixel problem:
I have a Canon powershot SX30IS camera; the quality settings for taking photographs is set on maximum.
But when in photoshop CS1, I look at the photographs at 100% they become badly pixellated.
so I checked the 'Image Size' and found that they are at only 180 pixels per inch.
I also have an Olympus 6MP camera. the photogs from this camera dont pixellate as much on viewing at 100%.
and the 'Image Size' dialog box shows 314 pixels/inch.
So isn't it weird that we spend 3 times the money on canon and get almost only half the resolution of an Olympus? there must be something wrong with the settings somewhere, but I have no clue...... please help.
Also, what boggles me is that why are the canon images at 180 pix/inch; while the olympus' tiny camera images are at 314 pix/inch!
It is a common misconception. The pixels per inch figure embedded in the photo has nothing to do with the actual resolution of the image in pixels. Your water droplets photos is 3240x4320, which is about 14 Megapixels.
The embedded DPI setting is simply an abstraction until putting the image on to a piece of paper comes up. For a more complete discussion, I'll link you to another thread on this subject that was started by Roz a few years back.

Thanks Steve :) I'm going through the link. please clarify one more doubt - how does the use of Digital Teleconverter affect image quality? my camera has two settings for Digital Teleconverter viz. 1.67x and 2.1x

If it is what I think it is, disable that function. It is digital zoom, which is essentially the same thing as cropping the image on your computer. It is a function meant for snapshooters who just want to post their snapshots and don't edit them. The camera may do some things to try and make the zoomed in image look better, but you can do a better job of it yourself.

hmm thanks for the suggestion. next time I'll shoot with this setting turned off and check the results.
