Which ISO do I use?
Nov 19, 2014 05:50:50 #
I was wondering which ISO to use on my Nikon D800? Supposedly the lowest native one (whatever that means). Currently I use 100 for most of my shooting. Could I go to Lo 1 or Lo 2 to get a better noise free image? Thanks in advance for the help.

You'll get so little noise at 100 that I wouldn't bother with Lo 1 or 2.

As I understand it you will lose dynamic range shooting into l1/2 ISO's. I suggest you experiment to see if it works for you. FWIW, my d810 is essentially noiseless at base ISO so I really doubt there's much noise in your images.

Yes, experimenting is the key, and I bet going high or low will still produce excellent results.

ISO 100 is the best whenever you can have it. Obviously, if you need to move it up or down to maintain the aperature and shutter speed you desire do so. ;)

L1 and L2 use a tripod

Correct.
You select the proper ISO, along with shutter speed and lens opening, depending on your lighting and subject matter.

I think cameras have the lowest digital noise at their native ISO's. That's usually ISO 100 or 200. I would only use Lo 1 or Lo 2 to get a slower shutter speed for photographing things like waterfalls, etc. DXo labs has a camera sensor comparator online. You can select up to three cameras and see their performance graphed on the same charts. Noise is one of the things you can evaluate. Plug in your D800 and check it out.

An ISO of 100 or 200 should be fine on your camera for high quality.
Though, not having a Nikon, what are Lo 1 & Lo 2 ISOs about? My Pentax K-5 has an Extended ISO mode that covers from 80 to 51,200.

Not only will you possibly lose some of your dynamic range, but the noise may actually go UP at the lo ISO due to too little amplification of the signal in the sensor.... which is why the higher base ISO was chosen as it was to begin with--- because it has the least noise!!

As I understand the guidance of experienced digital photographers, a cameraman should shoot at the lowest available ISO setting for the most noise-free images.
That said, from experience with my Canon 6D, I've found very little if any noise in its images up to ISO2000. But I try always to set its ISO to 50 whenever feasible to do so.
As a rule, though, I will employ a change in Shutter Speed, and maybe a change in Aperture, along with use of Image Stabilization, to keep the ISO setting as low as possible.

play with it!
I set up my both my cameras to "auto iso" for a couple reasons,
1) to see how the "camera" set "iso" for a particular scene and take note of it.
2) I had just started doing "manual" and it was a lot to take in setting 3 setting, I have since turned off "auto iso"..
but, will go back to "auto iso" if I am just walking around snapping off photos, but if I "set up" I will turn off "auto iso"
this worked for me, good luck

3 settings change amount of light received. ISO, F stop, and shutter speed.
It is important to know what f stop you need because of DOF (depth of field). Then important is shutter speed. Tripod yes or no? Subject moving yes or no. After that setting is determined, you want to set your ISO so that you have enough light to produce a picture. Very high ISO may cause noise, but most new cameras can go to ISO 800 without seeing noise. This is the type of discussion that we all need to have. David
