As Photoshop is what I use, that's what the thread describes, so for those who find that useful that's excellent. I was just thinking that for Lightroom users another thread could highlight procedures and differences, but someone else will have to do that one.

Generic sharpening comments could belong in either quite happily, but I just want to avoid confusion, if at all possible.

Can we start new threads for different subjects please - otherwise the theme of a thread becomes jumbled.

Radius has been mentioned above, but to see what happens just zoom into an image until you can see the individual pixels. Then adjust the radius and see the effect. You will then understand what is happening so much better than a lot of words can convey.

This is really a thread on Photoshop sharpening, so why not start another on the other question you pose?

Thank Ken, I've made it a Sticky.

Don't ask them to replace the screen on an M8...they only offer an upgrade to an M9. That's one reason why I prefer more mainstream manufacturers, there are more sales and more spares when things go wrong.

We'll stop this subject now, but reading the article that Algi refers to would be good advice for us all I'm sure.

Yes, but at what cost...a game for the rich? You can keep an MX flying if you can make the parts, and indeed they could be made. But the cost would probably be outof all proportion.

Matt, what happened to Sharpen-o-Matic, was it overtaken by improvements in software and cameras?

Helping bidding along for others is definitely against eBay rules, so I wouldn't advise either doing it or telling us about it. I believe it is called shell bidding, and likely to get offenders chucked off eBay.

Buyers who felt that they were being manipulated would no doubt be quick of the mark to report it as well. It's easy to forget that the whole world can read this forum, it's not a private conversation.

Sue uses High Pass some of the time at least and she feels happy with the technique. It doesn't really suit me, at least for my images, but Sue's pictures look fine.

It just shows that there are many ways to achieve the same thing, thanks for mentioning High Pass.

Just to add to the OP, it is of course possible to make selections of specific areas of the image and sharpen these individually. For example, we can leave skin unsharpened but sharpen eyes, lips, jewellery, etc. This can be done on separate layers and the skin blurred slightly to mask imperfections.

Another example might be sky, where a larger threshold might leave sky unsharpened and prevent JPEG artefacts intruding.

Sharpening can be very complex when we wish it to be.
