Will f8 focus to infinity? Whenever I AF on f8 it doesn't. I have to go typically to f/11. (I'm on a canon t2i with a 18-135mm)


u don't AF to infinity lol

Thats weird to me?!?!


Well dependant on the lens i would go by the sweet spot rule

2-4 stops less than the smallest aperture

turn focus ring to oo infinity sign on your lens

I removed the noise, as to why it's not very visible in this shot.

Thanks for the comment.

Exif:


Camera Canon EOS Digital Rebel XTi
Exposure 0.3
Aperture f/22.0
Focal Length 20 mm
ISO Speed 200

Urgh f/22?
Usually lenses are sharper between f/5.6 and f/14, go for f/8 or f/10 and you won't regret it. Just do a few tests to find the best f/ for your lens.
At f/22 you usually have high chances of diffraction.
And lower your ISO if you want less noise, there's a lot of light there so go for ISO 100.
Oh and if you have so many dust spots then you'd better buy a lens cleaning kit for a few bucks :)

Chantal I LOVE this photo!!!!
The proportions of the clouds and the buildings make it so impressive!
Ofc I don't like the leaning poles :lol: but that's just me with the wide angle :rofl:
This really looks like those houses will be desingrated with the end of the world of those apocalyptic clouds!!!
Great capture!!

Thanks everyone, I have learned a lot by just this one photo!

I am curious though, what would you use f22 with?

Yeah, I will try something a lot lower next time... I've no idea what I was thinking :s

I will do iso 100 next time. I can't seem to learn my lesson with that damned iso :lol:

I plan to go to the camera store soon :)

We all know you like your poles to be straight :rofl: ;)

Thank you Marie!

not at all, but they could get a little crisper, or go the other route with a much longer shutter speed, prob with that is there are too many clouds to give a nice effect



next take a pic as you did and then also time try:
open the aperture up a little
drop the iso, you cam should handle 400 or maybe a little higher
and then decrease your speed

you should prefer it


I am going to try something like this, thanks... it's good to know some settings I can test and try out. I probably was going to do this, but my battery died at the wrong time :(

I love noise, Did you focus to infinity? If so your lens needs calibration as the horizon buildings are way of focus. The clouds are as sharp as perhaps you can get clouds in this kind of light.

As other mentioned I feel the aperture selection was wrong for this shot. Am i correct in assuming that you wanted less noise and optimum sharpness from this shot?    f8 with a faster shutter even on iso 200 would have improved your results. Remember that diffraction will only really cause you problems when you are creating large prints


I don't know if it was infinity or not... I autofocused this one. I did want a less noise and an optimum sharpness (that seems to be my biggest issue is sharpness) so I have to learn how to work my aperture. I am going to try a much lower iso to see what I get. What kind of diffractions will I see? I'm not sure I understand the word 'diffraction'

basic explanation of deffraction, when your aperture is too small, the light that enters can be broken up and bounce around between the lenses
therefore lowers quality and sharpness

hope it makes sense, its way too early for me to be awake
