took this while hiking a few days ago

:tiphat:

i like the texture in this one a lot but it seems a bit blurry. like there was either some camera shake or not enough f-stop to get everything properly in focus

thanks...I've been having that issue with pictures...I seem to be having trouble perfecting settings for ultimate "crispness"...I was at f18 but I think 100ISO...maybe the ISO was my issue?...what shutter speed would you recommend for still images for ultimate crispness handheld? I think I was at 100-125 here.

a good rule of thumb is to always have a faster shutter speed than your MM of zoom. so if you are at 100mm, you need 1/125th or 1/160th. if you are at 200mm, 1/250th or 1/320th and so on. sounds like your shutter speed was a little slow for that shot. f/10 would have been plenty for that shot if not f/8 or even 5.6. f/8 will get most subjects completely in focus depending on what you are shooting and how far away it is.

Note that the rule of thumb is for 35mm (full frame) so, depending on your experience and steadiness, you may want to multiply by your camera's crop factor to get the equivalent rule for you, then add or subtract a stop.

Also the rule of thumb for aperture is two stops closed from wide open, but generally around f/5.6 to f/8 is best for most lenses. F/18 could start to show effects from diffraction, depending on final magnification. With such a flat subject, there's no need for a high DOF unless it was a macro shot.

Just when I stop following this thread, people start replying with solid, useful feedback.

So shooting with a 7D 50mm let's say. I should look at it as shooting at 75mm and be at 80+ shutter?

that's about right
