Less is more. Well, that's what I tell the missus

So...big stopper/small aperture fans, I am off to do some of this type of photography.

I have always been under the impression that stopping down reduced sharpness due to diffraction. Do you not find it an issue taking pics at F22 etc ? that picture from lakelord seems to have reasonably sharp trees.....

That's what I tell my accountant. He doesn't listen though.

Yes f22 will introduce softness to the image through diffraction. f11-13 is ideal for landscapes. I can’t see the exif on Lakelords pic, how do you know what aperture he used?

New Flikr has the Exif data on the right hand side of the image ( at least for me )

F22, IS0 100, 20 seconds at 20mm, lens was a EF20mm f/2.8 USM

Not liking the new Flickr at all, so thanks for that.

My recent waterfall shots were all taken at f/16 I think, couple with a Hitech 1.2ND - which if memory serves me correctly is a 4 stop filter. Given that all my shots where taken in bright sunlight I think the combination allowed just enough smoothing of the water while still retaining sharpness.

I'm not sure if I've posted this before but it is my first time posting from Flickr.

Do we think in practice though that diffraction (eg from f22) makes a visible difference when an image is viewed under 'normal' conditions - eg a web screen?

Just home from Skye Wow , what a place ! This one was edited the one night it rained , i retreated to the bar/lounge for some beverages and a play with some shots .

I don't think it does but, as usual, it depends what you want to do with the image. If you want to print 6 x 4's then it's unlikely anyone would notice. If you want an A2 poster on the other hand...

Stopping down past f/16 has very little use really. The only time I would is if I found myself without filters and needed a longer exposure. Struggling to think of any other reason?

Agreed - I never shoot beyond f16

I would quite like the option to get a proper photographic print done and hang it off the wall.

Just to satisfy my curiosity I just did a reasonably unscientific test with a ISO 12233 chart on my Tokina 12-24, it was sharp but low contrast at F4 with slight CA, sharp and almost perfect contrast from 5.6 to 8, slight dropoff to f13, noticeable loss of sharpness at f16 and getting bad at f20 and f22. My results seem to tally exactly with DXO Mark's measurements for this lens.

However looking at the pics at 1024x700 ( typical web resolution ) even the worst results ( 24mm at f22 ) were hard to discern....you are talking about the border of a black hard line going from 2 pixels wide to 4 pixels wide. At F16 and web resolution, almost indiscernible.

Skye at night by ChrisMarr, on Flickr

Taken on my last night in Skye , just behind the hotel i was staying in . I've never really done any photography at night so i was really pleased with this one .
