See the whole gallery here TECH SUPPORT Good Aspects Q.When I use Canon Zoom Browser to crop images from my EOS 40D, it wants to know aspect ratio, 4:3, 5:4, 3:2, etc. When I shoot head-and-shoulders portraits, I almost cut their heads off a little when I crop for an 8x10. So, is it better to leave a little more room around when shooting portraits? A.Yes, and this goes back to the film days. Digital (and 35mm film) SLRs, with the exception of Olympus and Panasonic Four Thirds models, capture at a 3:2 aspect ratio, which can’t be fit into an 8x10 format without some cropping. The Four Thirds cameras and digital compacts capture in 4:3 (some offer you a choice). To determine exact enlargement sizes, multiply both sides of the aspect ratio by the same number. A 3:2 camera’s images will blow up to 4x6, 6x9, 8x12, and so on. Pictures at 4:3 can enlarge exactly to 6x8, 9x12, 12x16, and so on.

Then upload your best shots to our Flickr page. See the whole gallery here TECH SUPPORT Crop Confusion Q. Your crop factor article in October 2010 was interesting, but I’m missing something. In November you said the Canon PowerShot S95 has a sensor size of 1/1.7 inch. Obviously that is not height/width. Is it a fraction that gives some dimension? A. Manufacturers use a weird size designation for the sensors in most compact cameras. The 1/1.7-inch designation is indeed a fraction: It is the measurement of the diagonal of the sensor chip multiplied by about 1.5 to 1.6X. (The reason for this goes back to—seriously—glass electronic tubes.) The diameter of a 1/1.7-inch sensor works out to about 9.5mm, relatively huge as compact sensors go. Where it gets really confusing is in comparing sizes of these small sensors, since a 1/2.5-inch chip (common in superzooms and small compacts) is much smaller than a 1/1.7-incher—about 4.3x5.8mm versus about 5.7x7.6mm. We promise from now on to give actual dimensions of sensor chips, not those wacky inch thingies.
