We're relocated to Lenses!

The filters covering the sensor have coatings that should be treated with care, but it's the first time I've heard of a manufacturing film.

Many things form films because of reaction with Oxygen in the air (air inhibited layers...)but if there were to be a film where would it go? Evaporate? Wouldn't that have happened in storage before delivery?

It's likely to be a sunny weekend, so lots of possibilities for photography. Some bird shooting may well be on the agenda, I have an 80-400mm lens that hasn't really had a good workout yet.

Adobe Camera Raw, the RAW converter built inot Photoshop.

Do please elucidate, what is this about? :

I'm going to suggest some different figures for Unsharp Mask:

Web image: 50-75%, Radius 1.4px, Threshold 3.

A4 or A3: 100-150%, Radius 2.1px, Threshold 3.

There's a lot of possibilities built into USM, but it goes beyond being basic stuff.

That's Part Five of the six articles I did for PU on basic Photoshop technique. The others are there as well and as a set they show how to simply organise, crop, adjust and sharpen images.

I used simpler versions of PS for these (7 and CS2) but the priniciple is the same for all versions.

Any questions, just ask.

Anybody is free to critique in as much detail as they like, but sometimes get snapped back at when the OP takes offence. This then puts people off.

If anyone wants in depth critique, then if they say so then someone may well provide it.

If I was to think of one thing that would improve a lot of images though I think it would be attention to the sharpening technique used. Some images are looking quite soft and even at 800 pixels wide they should be crisper. It may be a matter of matching the sharpening to the image size. It will not be the same amount that we need for a print.

Also, resize before uploading to Photobucket or wherever and the result will be better.

Don't forget you are now competing with lots of people who were not previously aware of that item...some you know, many you don't. If you want it, it might be an idea to buy it very quickly before someone else jumps in.

If you don't like it, it can go back on eBay and needn't cost you very much as an exercise.

The K-r is an obvious choice, unless you need weather sealing, in which case the K-7 or K-5, depending on availablity and budget.
