Uh oh. This sounds like a request from someone who doesn't know what they're talking about. Output resolution (which is in pixels per inch, not dots per inch) is independent of image dimensions (in pixels). You need to ask them for either the pixel dimensions they want (which they probably won't know) of what their intended print size is (in inches or centimeters). >I have LR 3.

You can control everything in the Export dialog. The parts of the Export dialog are as follows (scrolling from top to bottom): * Export location * File Naming * Video * File settings (file format, color space, bit depth, etc.) * Image sizing * Sharpening * Metadata * Watermarking * Post-processing The first two items are at your own discretion. The third is non-applicable. File settings should, unless the recipient specifies otherwise, be JPEG file format, sRGB color space, high quality (how high is up to you) Image sizing is where you set parameters for the pixel dimensions of your exported image. You know that the output resolution needs to be 300 ppi (though it really doesn't matter - the recipient can change it to any value they like) but you don't know what actual dimensions in pixels or inches are required. This is the information you need to get from the person you're sending the image to. (I'd leave sharpening off and skip the Metadata, Watermarking and Post-processing sections for this.) -- Mark Roberts - Photography & Multimedia www.robertstech.com -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
