Hello: I would like to know how i can tune my image resolution exactly with the size and DPI. For example how i can have an image og 1024×768 with 150 DPI? When i open the final render (TIFF) in Adobe Photo Shop the image is smaller than the first one because the DPI are different. Thanks Regards Mauricio Escalona Duomo Ltd.

Mauricio: /_______________________From your message________________________\\ I would like to know how i can tune my image resolution exactly with the size and DPI. __________________________________________________________________ Image resolution is easy as you just fill in the width and height, but you knew that. A .tif created in 3DS may show up in Photoshop as 72 DPI or even 1 DPI by default. This can easily be changed to whatever you desire with Photoshop's Image/Image Size command off the menu. Constrain both the File Size and the Proportion and you can then alter the Resolution of your image to be whatever you'd like without changing the number of pixels. In 3DS I know of no way to specifically render to a DPI setting. /_______________________From your message________________________\\ For example how i can have an image og 1024×768 with 150 DPI? __________________________________________________________________ Yours could be a loaded question so I'll ask a few questions of you so I can understand what your requirements are. What is the maximum resolution of your printed output? What output device are you using? What is the final size in inches of the printed area you wish to fill with your 3DS .tif file? (1024 x 768 is a computer screen resolution which does not translate too easily to a common printed page size.) 1024 x 768 at 150 DPI will yield a printed area of 6.82" x 5.08". Is this the size you wish? If so, render at 1024 x 768 in 3DS and change the DPI in Photoshop as I mentioned above. Once saved in Photoshop the image will forever be recalled at that DPI. Bob

Mauricio, In addition to what Robert told you you should be aware that if you're going to an actual printing shop that the LPI they give you (150 line screen) will need to be rendered at about twice that (300 dpi). So, if you want to print a 5×4 image with a 150 line screen you'd need to render to 1500×1200. DPI and LPI are really only a function of the output device. I know it can be confusing at first though. You'll get it. DM
