Sharpness and Displays

I had yesterday the doubious pleasure of viewing some of my own A700 pics on a CRT (cathode ray tube). Maybe some of you still remember :mrgreen: I was surprised about the softness. I think my LCD is much sharper. Is there any index to measure sharpness of a screen (and I think printing is even sharper)? I know there are colour-calibration devices (still don't own one though :? ), is there anything for sharpness? I feel the difference between a CRT and printing might be quite large so one might have some surprises when printing :roll: .

Most monitors are running 72 - 96 DPI resolution. If you have the resolution set lower, it will look even softer. Try setting the monitors resolution at the highest the monitor can do, and see if that helps.

PS, you look much more relaxed in the new pic.

That's right---LCD displays generally are much sharper than CRTs. That's a natural consequence of the different principles of function (and it has nothing to do with DPI). So when preparing web images using a CRT monitor and sharpening them to look good on the CRT, they will look hopelessly over-sharpened on an LCD monitor.

And sharpening for print is a different kettle of fish still ... you cannot go by the visual appearance on the monitor, no matter whether it's CRT or LCD.

This is completely off topic, but I agree with Dusty, your new avatar is a much more flattering photo.

I have never liked veiwing my a700 pictures on a CRT television. In addition to the softness, there appears to be a lot of cropping and distortion in the veiw...though now I'm thinking there's a setting I need to switch for that latter problem.

I get quite nasty flickering when I view pictures through my TV set. Is this just me or does everyone get the same thing?

Simple rotation without resizing will not affect absolute sharpness of an image, regardless of the degree of rotation. But it might appear to do so on your screen, since your monitors resolution is only 72-96 dpi.

Nevertheless, I always save postpone final sharpening until the last post-production step and RAW pre-sharpening until after rotation/straightening.
