I ran some simple tests today and found that there's no need to be bothered with film aspect ratio to match the perspective with a photo. Just keep aspect ratio of the "Current Camera" and Height/Width ratio under "Resolution" in render settings to equal values and you'll mimmick a 35 mm photo camera. By resizing the viewport, or the picture size, you are able to render outside the area that the real world camera shows but it won't change anything to the perspective. In other words there is no direct relation betweeen the picture size or picture aspect ratio and the lens angle in rs3d camera settings. > Nevertheless I had to set the Focal length to 160 mm instead > of 191mm or > 48,25 as mentioned in the exif data. You'll have to multiply the focal length from the exif data by a constant to find the 35 mm equivalent. For my camera this constant is 3.93, probably different for yours. Regards, Frank Bueters
