Resolution vs dpi Which is the equivalence between the CCD resolution of a digital camera and the dpi of a printer when you print the photo? In other words, how many dpi`s do I can get from a 4 Mpix digital camera? Thank you

The resolution of the digital image has to be sufficient to give the printer the information it needs. The good news here is that you can ignore the inflated dpi figures the printer makers give us, as they are meaningless. The resolution of the image that you feed into the printer needs to be only between about 240 and 300 pixels per inch (ppi) to print a true photo quality print in the typical injet printer. To get the best resolution (measured in ppi) out of your 4 megapixel digital camera, be sure that you are setting the camera to shoot at the best possible image quality. Open this image in Photoshop (or Elements) and go to Image/Image Size. Do not check Resample, but check Constrain Proportions. Enter 240 in the resolution block. Click OK. The resulting readout will tell you the print size you will get.
