  • Sharpening

    Having returned to my home town a few months ago I've started to attend a local camera club which still meets during the summer months. After the last meeting a couple of weeks ago I mentioned to one of the committee members that I was struggling with sharpening my shots and would quite like a session on that subject if anyone there could help. One or two others joined in for a few minutes and I left thinking no more about it. Until, that is, last week I received an email from said committee man saying that as it seems I know more about sharpening than anyone else in the club, would I be prepared to give a demonstration of how I do it. Time to panic So, here's a shot I took on Sunday evening at a free concert by Suspiciously Elvis down by the local river - straight conversion from raw to JPEG:



    I then applied Snaarman's recommended settings for preparing images for printing (thanks Pete, I'd have got nowhere without your help) and got this:



    Can't be sure yet how it looks here, but on my PC it seemed rather noisy so I then ran it through Noiseware and was really pleased with the result:



    The difference between the first and last is substantial, and I'm starting to think I'm finally getting somewhere, but any comments or advice will be most gratefully received.

    Re: Sharpening

    Aha :-)

    Glad to help... (My sharpening suggestions come from this thread, if anyone is interested http://e-group.uk.net/forum/showthread.php?t=10943 )

    My ideas were based on a long long rambling article on the web somewhere. The critical nuggets I took away were:

    1: Sharpening for small pictures for the web is a very different beast to sharpening for prints.

    2: If you are preparing for a print, then when viewed at 50% on your screen, your image should look slightly over sharpened, because the printing process tends to soften the image a bit.

    There are many different and esoteric methods of sharpening for prints and you can spend a whole evening on one image if you wish. Personally, I have a general method I use and I don't vary it for fear of messing up

      I'd recommend anyone to beg, borrow or steal (or even buy!) a copy of the late Bruce Fraser's "Image Sharpening with Adobe Photoshop CS2" from his "Real World" series. It'll tell you everything you ever wanted to know about sharpening.

        By coincidence, I am writing a beginners guide to sharpening on DPNow.com It should be published tomorrow (Friday).

            I'll keep an eye open for that Ian - I'm sure it'll be an interesting read.

                Re: Sharpening

                Ok - a bit of an update. Of the originals (before posting on here) pic 2 was sharper than pic1 but very, very noisy (shooting at ISO 800 may have contributed). Pic 3 was as sharp but noise free. I think on here (after resizing to 800 x 600 and after posting I could see the differences weren't as clear) there's very little, if any, difference between pics 2 and 3, both of which are noticeably sharper than pic 1. And on the 7 x5 prints I did for the demonstration on Tuesday (the biggest I could get in one hour from Tesco) the same applies. However, after having 16 x 12 prints of each done to take to the next meeting, there is definite (but not too bad) noise on pic 2 but not pic 3 which, to me at least, looks really good. So, thanks once again to Pete (Snaarman) - but tomorrow (hopefully) we get Ian's beginner's sharpening guide on DP Now and sometime soon I will get the book Jim recommended (above)!! Do I start again - or stick with Pete??? Watch this space lol

                  Re: Sharpening

                  Just as a footnote, I'm beginning to have just a suspicion that some photo editing software exaggerates faults. For example, one image I was working on in Elements 7 a while ago looked a bit noisy. So I opened it in Noiseware to fix it and it looked as though it had been taken in a snowstorm, which it of course fixed in seconds, making the software look good. And the noisy pic 2 mentioned in my previous post (worked on in Elements 9) showed hardly any noise, at the same magnification, in Windows Photo Gallery. Anybody else found the same?
