To push or not to push

I finally had my first couple of days out in the field putting the K-5 through its paces. What an amazing machine. Remember those days of shooting Kodachrome when if you were off by more than half a stop it was a tosser? Not any more.

I have put together a brief discussion of the pushing capabilities of the K-5 here:

Thanks for not discussing it here. I doubt anyone would be interested.

Franky, I could not navigate on your Flickr page, but it could just be me :-)

However, I gather from your comment that you used ISO 400 and pushed it 3 stops to be the equivalent of using ISO 12800.. If so, your math is off. 400/800/1600/3200/6400/12800.

Ouch! Harsh!

Actually, i disagree. There is actually a setting in the camera which will automatically underexpose for you, because shadows are much easier to correct than blown highlights in the K-5. The setting is called "Highlight Correction".

There is also talk about circumventing high-ISO low level NR by shooting underexposed at 1600 and pushing. Talk to JohnBee about it.

@SpecialK: It was pushed 3.4 stops according to my photo program to get to an equivalent luminance level of the ISO12800 shot. This was just a confirmation for me of what JeffJS had already discovered when he pushed his dog shot 10 stops or so and still got a very usable image. No way I could have done this with my K20.

It was a total of about 4 stops .. Glad to see it confirmed though..

Thats correct... but I think it also sets your ISO to min 200

Actually, it sets the min to 160, because in reality, at ISO 160 it is shooting a shot at ISO 80, 1 stop underexposed, and pushing it in-camera. This will make the most of the increased dynamic range of ISO 80.
