"I guess this is the place to ask what is with low ISO settings on my D90"

I was in really bright light and I wanted to go as low as possible on ISO. The camera only will go down to 200 then letters appear. LNN or something like that. I don't have the camera at hand. My brain wants to shoot at old kodachrome settings. I guess I am just a Kodachrome guy stuck in the digital age. So what is this L something. Is this shorthand for "you've gone low enough fella"?

Hi John,

L 0.3 = ISO 160
L 0.7 = ISO 125
L 1.0 = ISO 100

= (equivalent)

You could always add a ND filter to the front of your lens to allow you to reduce the shutter speed or increase the aperture even more.
Good Luck and Enjoy your Nikons!

Best Regards,
Marty

Thanks, I wonder why they just did not continue with the numerals. I guess it is another example of the inscrutable mind of the Japanese. I figured if it meant lower numbers there would be numbers. I still have a lot to learn. Next I have to figure out very long shutter speeds. Is there such a thing as a B setting? JB

Hi John,

The reason for the L and H settings is they are not as accurate as the ISO settings designated with numbers.
Good Luck and Enjoy your Nikons!

Best Regards,
Marty

Wasn't B setting for bulb?
For a long exposure just keep dialing down til you get to where you want to be. Certain amount of guess work involved.

Yes, B for bulb. Put the camera into manual exposure mode, then crank the shutter speed down (slower) all the way to the end.

As already noted, you have L0.3, L0.7, and L1.0 options. The reason Nikon doesn't use numbers is because these ISO levels are "fake"...in the sense that they're being created by reducing your highlight range.

All cameras have roughly 3 stops of highlight space above metered gray (about 12.7% gray.) When you shoot at the "L" ISO levels, your highlight space is reduced, so you may clip some highlights that you wouldn't have clipped at ISO 200.

The benefit of these ISO levels comes with scenes that are mostly dark, such as a sleeping black dog on a dark floor. Shooting at the "L" ISO levels reduces noise. In such a scene it's no problem to lose the highlight space, as there are no real highlights to speak of, and the improvement in shadow noise is noticeable.
