The main thing you asked about was the cost. My ext tubes cost about £100 and are very flexible. But recently I bought a Raynox 250 clip-on converter lens, which I got from Amazon for £42. I'm surprised how good it is. Very sharp and clear, although you don't get much DOF as it takes you pretty...

Talking of photographs... surely you need to update your avatar?:lol: Kim shots

Then you must love doing the other stuff more? :)

What a let down! I thought you were asking us about sex (read it again) until I got to the last two questions. :lol:

OK, that;'s a good example of where it comes in useful - 18mm on a full-frame, is that right? And persumably you couldn't stand further back. There is not much distortion there either. Good shot!

If you have Photoshop Bridge and you collect your landscapes together in one folder, it's useful to do a search based on focal length setting; eg. less than 24mm, and see historically how many shots you have actually taken at a wide setting.

One thing I didn't mention at the start is about height. We are often concerned about going wider, but that also means going higher. A lot of very wide shots have to be cropped because there is too much relative area for sky and uninteresting foreground - just to get more width across the scene.

There seems to be something of a thing recently about going very wide on landscapes. Even on a full-frame camera people seem to be switching to a 17-40 lens. I even thought about it myself, then realized I don't really need one as I have a 24-105 on my 5DM2 (full frame). Perhaps it's more...

It's certainly worth experimenting with. And don't forget, when you are doing the shot for the upper background area, if the sky is very bright you can also stop down to prevent the clouds blowing out. And the foreground shot can be exposed for the foreground as well as focus. So, you will get...

I've been meaning to try this for some time. Took a shot of my garden at f/16 focussed about a third of the way in. Canon 5DM2 with 24-105mm at 40mm. Same standard sharpening applied to all shots. f/16 single shot Then took two shots on the same framing, but at f/8. First focussed on...

My brother's bigger than yours...:lol: Actually, I did say in post #3 that f/8-f/11 is best. And it is - especially on a cheaper camera lens.

As well as the android app I quoted above, there's also an online version here DOF calculator

There are two ways you can blend. I do a lot of stacking using CS5 and helicon. Mine are still life (see my website) and I haven't tried this method with landscape shots, but I see no reason why it shouldn't work. All Helicon (or Photoshop) does is select the areas that are most in focus across...

There's a pretty good Android app for hyperfocal distance Android app for DOF
