Hi all,
This is the problem I have : I watch a video on my PC using any utility such as, for example, CyberLink's PowerDVD. I pause the movie to capture a frame to the Clipboard, then I paste it into PS CS3 via a newly created document.
Because the movie was shot and recorded on the DVD in widescreen format, therefore using non-square pixels (wider than they are tall), the still image in PS appears "shrunk" horizontally. I then go to Image|Pixel Aspect Ratio and set the ratio to, say, "D1/DV PAL Widescreen (1.42)", as I am in PAL-land. The still image now looks fine, and I can save it, for example in TIFF format ; it will retain its "non-square pixel" attribute, with the black bands on top and at the bottom.
However, what I utimately want to do is use that still image on the Web, so I need to save it as a JPEG image, and this is where the problem happens : the JPEG conversion reverts those pixels to square ones, whether I use the "Save for Web and Devices..." option, or just the "Save As..." one.
How can I turn my very heavy TIFF into a much leaner JPEG, while retaining the non-square pixels that give the image its correct proportions ? Is there a way around this problem ?
I'm not used to dealing with non-square pixel images, so any help and tip will be greatly appreciated. Many thaks in advance.
Dominic.
