Low camera pixel reolution setting - Kodak EasyShare DX7590 Digital Camera

Digital pictures have a set pixel density (resolution) when they are taken This can be adjusted on some cameras and on others it cannot. IF you are using a camera with a low rating or you have your camera set that way (more detailed picture with higher settings consumes more disk space) then enlarging the picture causes it to become blurry, Check the camera and see what the Mega Pixel rating is. The bigger the number the better and more expensive the camera..

DPI (dots per inch) is an output specification and is meaningless to the camera. The camera puts in 72 simply because it can't leave it blank. 72 dpi is commonly used when viewing a picture on a computer screen.
Suppose you have a picture that's 3000 by 4000 pixels (12 megapixels). If you make a 4.tinch by 6inch print (4x6) then you'll be printing at 667 dpi. If you make a 12 by 18 print of the same picture, you'll be printing at 222 dpi. It's the same picture, just printed at different sizes (and different dpi). The dpi value is set when you print the picture, not when you take it.

Press the menu button and go to the shooting menu (the little camera icon). Scroll down to "movie settings." there are three quality settings. Select the one you want then try a test shot. The higher quality setting (1280 X 720 pixels) uses more memory. The default setting is 640 x 424 pixels and the lowest quality setting which uses the least amount of memory is 320 x 216 pixels. Sound is off by default so if you want to record sound with your video, you need to turn the microphone on in this menu as well.

Uploading them via the SD card will have no effect on the resolution.
There is a difference between image grain and image pixelation.
If the resolution is too low for the size you are printing the image will pixelated, meaning that it will be made up of lots of little squares.
If the image is grainy it may be that you are shooting images in low light at a high ISO setting on the camera. Typically with the lower end Canon cameras anything above 800ISO will start to look grainy.

This is normal behavior when shooting in low light. Just like when someone is speaking softly into the phone, you may turn up the volume on your end. Any background noise, you can now hear more.

Similarly, when there is low light, the camera turns up the amplification on each pixel. Some pixels naturally have a bit more background noise than others, and these show up as bright spots. A higher ISO setting where the camera is more responsive to light is where this occurs.

At a high ISO, taking a picture of pure black shows up as a mottled grey with a few bright spots for pixels that have a lot of noise.

You can overcome this if you have a tripod - set the camera to manual and a use a lower ISO setting. Rotat the selection wheel to M for manual and then press the ISO (just above the function set) button to scroll through different ISO settings.

Photoshop and other programs have noise reduction tools and a tools to remove "hot" spots as well.

Please check the image size (pixels x pixels) setting or the resolution (MP). Seems like the camera is shooting in low resolution. Have you used this memory card on a mobile phone or another camera? Format the memory card and try again.

1. Right click on the desktop
2. click Properties
3. click Display Settings

Change the color qulity to 32 bit (or the highest)
And change the reolution to 1024 x 768 pixels

if taking pics for a web site you want the camera at the lowest reolution possible-1-2 mexapixels to keep file small and easy to view on web-if you took pic already at higher quality only software can downsize and compress pics-600 x 480 pixels is about 1 megapixel

Picture resolution is the total number of pixels in your picture (those little colored dots when you look really really close). It's expressed in megapixels and is simply the product of the number of pixels in the width of the picture times the number of pixels in the length. For example, a 7.1 MP camera takes images with a resolution of 3072 pixels width by 2304 pixels height ( 7.1MP = 3072 x 2304).

Pixels/inch refers to the resolution of your picture on some external viewing device (printer, computer monitor, etc...). It has nothing to do with the settings on your camera. It's equal to the number of pixels in the picture divided by the width of the displayed picture on the device. For example, an 8 x 10" printed picture has a width of 10 inches. If I wanted to take full advantage of my 7.1 MP picture by printing it as an 8x10, then I should look for a printer capable of printing 707,789 pixels/inch. Now I'm pretty sure there's no printer currently capable of this feat.

The example above shows that the rush for more megapixels is not necessarily where consumers or camera manufacturers should be focusing their attention. Most people really only need something around the 3MP range for printouts or display on their monitor screens.

What you are seeing is the difference between "pixel count resolution" and "embedded resolution". So in your example 2272*1704 is the actual pixel count resolution as recorded by the camera & 72 is the embedded resolution that tells the software (in this case photoshop) what the intended use of the picture will be. 72 ppi is the default for web pictures. You can change this in photoshop by going to the "Image" tab & select image size. The window that opens will show you the pixel dimensions i.e. pixel count resolution and the document size & resolution 72. You just change it to 300 for printing. You can change the default to 300 by going "edit", "preferences", "units & rulers" and setting the values for "new document preset resolutions". This is a complex subject, I recommend looking at the following web page: http://www.fotofinish.com/resources/centers/photo/resolution.htm
