How do you change the DPI I am sending some photos for a website, but they are not that sharp when is reduced to thumb size. They are 6 megapixel. The web designer told me that is the dpi "75" that I have to change to 150. I have an Ibook and have not found the way how I can change it. Can you give me the right information? Thank you, Julio

The stage at which to do this is after you've deleted the junk and tweaked the white balance, brightness, cropped, fixed dust spots, whatever. Save full size image files on CD as an archive. Go back to your original edited files. Open each image in Photoshop or Elements. Go to Image/Image Size and check Resample. Also check Constrain Proportions. Enter 150 pixels-per-inch (dpi is a printing term) as your resolution. Then enter 750 as your image length, 600 as image height for a vertical. Double check this resolution and image dimensions with your web designer. For betterphoto I use a res of 75 and the dimensions given above, but the designer calls the shots here. OK this and sharpen them with Filter/Sharpen/Unsharp Mask. For jpg images of this size, the settings can be 100/.7/2. If this degree of sharpening looks too severe, go up to Edit (if Photoshop) and cut back on the Unsharp Mask. If you use an imaging program other than Photoshop or Elements, you can do these operations, but it's hard for me to tell you exactly how to do it on an unfamiliar program.
