Do you know your DSLR camera's highest pixel dimensions by heart?

Nope...the only thing I care about is the sensor format (full frame, APS-H, APS-C, etc.), so that I know which lens to use to frame the shot like I want.

Nope. Why would I want to know that? I do have it posted here on my computer so I can do calculations for people on Answers, but it really has no practical use for me. I can say, "This crop is only 4% of the original image," if I know the maximum pixel size, but that's about the only thing I think I've ever used that information for. Once I bought the camera, I was stuck with the output format determined by Nikon. I always shoot the largest image size anyway. It is more important to me to think in terms of 8x12 being cropped to 8x10 or held at full format rather than 4288x2848 being cropped to anything. I try to "crop in the camera" as much as I can when I take the shot instead of counting on the generous number of pixels to allow me to be sloppy in the field so I can fix it at home.

Yes, because it doesn't hurt to know (and if anything, it helps me). Also, it's not difficult, since after seeing it numerous times, it has become easier for me to remember. It helps when judging how much I can crop off a picture. I can say, "Oh I'll crop off this entire half, and still be left with a good 6MP shot." Haven't needed to think that yet, but it's still an option. It helps, when I compare with a friend's camera, to know the technical difference between our shots. And I would need to know if I were to make a large print. Sure, I might not have to know the exact number since I already have a feel for it after all this time, but again, it doesn't hurt to know.

No, it serves no purpose for me to have that memorized EXACTLY. I do know it is "somewhere in the 5000 x 3000 range, 21mp", but that is only because I see it in Photoshop. I have enough things I HAVE to remember in life without further cramming my brain with stuff I have no need to memorize. I also do not shoot with ANY intention of future cropping. Sometimes it becomes necessary, but it is hardly a normal part of my photography. What I compose in the viewfinder is my intended output.

Of course. Of course. That is basic photographic knowledge. That is the first thing I review when shopping for hardware.

My current camera offers an image width of 3008 pixels.

Very important to know that because some situations and subjects will not really work with the pixel limitations of your hardware. You need to be aware of that. Also, it will help you make decisions on how to compose the image with cropping in mind.

Excellent question! Starred.

NO. Why to by-heart what can be referenced. The holding and retrieving capacity of the hard disk in brain is limited , so better to use it judiciously and not cram it with un-necessary information.

No. I do not have a good memory for numbers and hate math.

No. Why..because I am a numerical dyslexic, but I don't feel it has ever effected my end product.

No - because I have three of them and they are all different.

3872 x 2592

3888, because I own two 10.1mp cameras.
