Hello, Guys
Just wonder when should I use ISO L 0.3, L 0.7 or L 1.0 on D90? Almost all the tutorials or documents online mention to keep ISO as low as 200. So why not as low as L 1.0 (equals ISO 100)?
Please advise.
Thanks,
When should I use ISO L 0.3, L 0.7 or L 1.0?

one situation would be when you are shooting in strong sunlight and you want to add flash. If you can't (or don't want to) shorten the shutter time, or stop down, you can lower the iso to allow you to add more flash.
Another situation would be to slow down movement of water.
In general, whenever you would reach for an ND filter, you could do this for 1 stop with minimal impact on iq.

Ok, so what u r saying is: ISO L 0.3, L 0.7 are L 1.0 are not going to give as good IQ as ISO 200. I would need them only in special situations, right?

The L0 settings are non-native to the sensor. The camera adjusts exposure and artificially makes it the same as lower ISO. There is no noticeable drop off in image quality, unlike the H0 settings, that I've seen (at least in RAW captures).
I only use the L0 settings when I really need to slow down the shutter speed, such as if I am trying to get silky smooth water in a river or waterfall.

Ah this reminds me, I have always wondered, why is nikon's native iso on most cameras 200 (I can only speak about the lower level ones), and canon's is 100. Wouldn't a native of 100 imply a more useful sensor for shooting in brighter settings, or less noise for longer exposures? (Don't shoot me please! it's an honest question!!! I've always just wondered.) If you can't answer my second question, please just tell me why nikon's native 200 vs 100

Maybe for better quality at high iso they sacrificed the low iso?

I loved shooting ISO100 CCD sensor Nikon camera, it was much cleaner (noise free) than ISO200 on CMOS sensor cameras, sadly the low settings do not help on CMOS sensor cameras.
Lower ISO is generally meant for when you need to reduce shutter speed due to bright light, or for less grain, in the case of film. Since the Pro/Semi Nikon cameras have shutter speeds that max out at 1/8000s or more it isn't a problem, but there were times with the D90 that I maxed out my shutter speed (1/4000s in bright sunlight) and everything would have been blown out at ISO200.

Yeah, that's exactly why I've always been curious. I usually shoot with 100 speed with film, so coming from that background, by setting your base as 200, it seems that there is automatically a small increase in grain/noise which would be exponentialized when either doing long exposures or more so when cropping in.
I wasn't aware that it was a difference between the CCD and CMOS sensors in the cameras, does this mean that the d3000 has a native of 100??? Quoting from the Nikon site this would seem to be the case
"Wide sensitivity range of ISO 100 to 1600; a Hi 1 setting increases sensitivity to ISO 3200"interesting. What are the differences between the ccd and cmos sensors. sorry this is getting so offtopic. If someone just wants to direct me to a place to figure that out, that'd work too.

CCD and CMOS sensors are made differently, a wiki search should give you far more detail than I care to type out.
The D3000 uses a CCD sensor, and yes ISO100 is native, just as it was on the D60. CMOS sensors could use lower sensitivities, some of Canon's CMOS sensors have native ISO100, so that isn't the reason why Nikon CMOS sensors start at ISO200.

Ah I see now, thanks. It seems that everything is native 200, until you hit the d3x which is native 100.
strange. I wonder what the official reasoning is.Posted 3 years ago # -

That's weird, the D40 starts off at 200. Maybe it's a D40 thing?
And yeah, I would assume low ISO values are used when you want a quick shutter speed or when you're shooting in very bright light.

Thanks guys.
I think I will just use ISO200 and Try Lx on beach:)

Just remember guys that ISO is a standard but how manufacturers rate their camera's ISO isn't. In other words ISO 100 on a canon might actually be higher like ISO 125 or ISO 50 is actually 80, 400 is more like 500, 800 is 1000, etc., etc. Nikon comes the closest to achieving "real" ISO numbers. ISO 200 is really ISO 200.
So canon's ISO100 might actually be closer to Nikon's ISO 200. Canon just likes to play the "we've got better specs on paper" game a lot. Also higher ISO not only give you more noise but also less "saturated" colors. I think Nikon has done a great job of balancing things out. So I wouldn't worry too much about getting lower ISO. You can always add ND filters in very bright conditions.

I was wondering: My D300 has a normal range from 200 to 3200 and I do believe the Sony A700 with the same sensor start at ISO 100 - 1600 Ext to 6400 (OK the Auto range is from ISO 200 - 1600)

Another reason why I like Nikon. They don't "cheat" as much as the other guys when it comes to their camera specs.

I agree that the ISO rating is accurate. I get the same reading from the D300 at ISO200 as my film camera at ISO200.

Yup, Nikon is awesome in that sense. Not that their not awesome in everything else too :^)

ahh thankyou very much Niko.
I was wondering if you had any links to the canon information though? I am curious how their numbers match up. While Canon may be lying about the actual iso, I doubt their 100 iso base is equal to Nikon's 200 (on the camera's where that is the base)
Also on the few nikon's that 100 is the base, do you think that is really accurate, or is Nikon fibbing a bit there?-Foofie

DxOmark sensor checks the ISO sensitivities as part of their tests. Here's a comparison of the D700 and 5DII, and if you click on ISO sensitivity it shows the measured versus manufacturer spec.

I believe ISO200 on the Canon Xsi (450D) was actually ISO160 or something close to that.

But Nikons ISO 800 is about 700 and 3200 is about 2600 etc.. just check out the DXO graphs. Only FujuFilms S5Pro is spot on in terms of ISO settings. So the S5pros 3200 is about equal to nikons or canons 4000 or more.

I did say "not as much". Nikon has always been pretty "consistant" with their ISO range.
Fuji actually cheats a lot more than Nikon according to dpreview's "calculations". Canon has gotten better with their "calculations" with recent models but early cameras were pretty off.
Look at dpreview's graph of the canon 5D
http://www.dpreview.com/reviews/canoneos5d/page21.asp
It's basically dependent to camera by camera and manufacturer by manufacturer. That's why it's tested by dpreivew, DxO, etc.

What I still wonder is what happened to ISO 50 as I find many practical uses for it?
The D3x is obviously excluded from this.
