canon digital camera elph 100 image
Danny
It's a Canon Powershot SD750 Digital Elph... I'm not sure what to do, my pictures keep turning out grainy! It's no fun!
Answer
Answer: The reason of the "grainy image" is due to the fact that the ISO (a number which sets how sensitive the digital sensor/film is) is too high.
So in general, setting a high ISO means that there are more chances of those "grains". Setting a lower one will get less. So grain in ISO 200 > ISO 100. I suggest to refer to your manual how to "Change ISO" settings or something alike. Check the index, I am sure you will find you solution there. It is referred in photography term as "Photography Noise".
Extra: You may ask why would they have that for? Well, the reason as explained above, ISO is the sensitivity level of the film (digital film inside camera) which takes the picture. So the effects:
Examples:
High ISO: More sensitive to light -> Reduce exposure -> Sharper Photo (when you take moving objects) ~ but more noise
Low ISO: Less sensitive to light -> More exposure -> Blurry photo (when you are taking moving objects) ~ but less noise
It is kind of a compromisation. Hope this helped.

Can I obtain 300dpi images with a Canon PowerShot ELPH 100 HS Digital Camera?
William
I need TIFF or JPEG images with a resolution of 300dpi or greater. I've read that dpi is meaningless except for printng, but with various cameras I'm only getting 180 dpi images.
Answer
The dpi number in the image meta data (EXIF header) is meaningless. The various camera manufacturers set this to all sorts of numbers from 72 dpi to 300 dpi. You can set this to anything you want and it doesn't affect the image. For resolution, you worry about how many pixels wide and high your image is.
If you want, you can set the dpi number in your original image to anything you want using ExifTool, Nconvert, or a photo editing program without affecting the number of pixels in your image. If you are doing commercial printing, then you need to be aware of dpi and pixel dimensions which you set up in your photo editing software and/or desktop publisher.
So, why do you need 300 dpi? If using your personal printer, you just throw an image at it and it will scale the image appropriately. Even drug store printing doesn't care about your image dpi setting.
