Sharpening problem

vulcan57

I have just got a Canon 7D after using a 350D for a number of years. I am seriously happy with a lot of the pictures that I have taken particularly on the camera screen. I have uploaded a number of pictures to airplane-pictures.net and the vast majority of them they have rejected saying they are soft and in need of more sharpening. When I have them on my computer screen they seem ok and when I have sharpened them further for re-uploading they appear to be jaggy but then they are accepted?. The only thing that I can think of is that my old CRT monitor went bust a few weeks ago so I went out and bought a 22 in LCD TV and linked it to the computer via a HDMI cable. Everything else on the computer seems to show up pretty much OK. However the resolution of the TV is only 1360 * 768. I believe dedicated computer LCD monitors have a greater resolution. Could this be the problem ? Any advice would be much appreciated.

Do you have the PC output matched to the TV resolution? It just won't look right if there's any down/up scaling.

Are you shooting RAW and doing the sharpening yourself or jpeg and allowing the camera to sharpen for you?

Can you post some examples...

If you're going to splash for a good DSLR then you should back that up with a decent monitor, get yourself a 1920x1080(fullHD) panel and you'll have much better time during post.

Can you post some of the images?


It would also help to know how you are shooting and what you are doing in PP.

TV LCDs and monitor LCDs actually display information slightly differently. I can't remember all the specifics off the top of my head, but in a nutshell, monitors will always give a more accurate image than TVs even when using the same native resolution. If I were you I would get a decent monitor - especially if photography is an important hobby for you.

Someone else touched on this already.
You need to do you r sharpening at the same resolution as the final output. (although.. you might get away with doing it as some divisor of the final output.. going for HDTV.. 1600x1080??, you might be able to do it at 800x540 and have it still look alright when viewed at 1600x1080.. I'm not exactly sure of what the actual HDTV resolution is.)
Another trick is that when you're doing your sharpening, you should be looking at the important section(s) of the image at a 1:1 ratio ("actual pixel" size) otherwise you're looking at a resampled-for-your-screen-resolution version of the image after it's been sharpened, and not at the sharpening you're doing.

(It is a good idea to also view it carefully at other sizes before you call it done.)
