Excellent--a keeper for the ages and it really does not look like a high ISO shot at all.

Very nice...what is your jpeg settings for all the parameters that can be set in camera. like the saturation, hue, high/lowkey adjust, contrast, fine sharpness/sharpness etc.

thank you

forgot to mention that this was a pulled exposure (ETTR) as well !

the only adjustment I did was setting the highkey(+5,) fine sharpness(+2) and contrast(+2), although by doing so, I'm also threading the waters to a more intensed noise. glad to have the noise worked out just fine.

K-x ISO 1600. No banding or noise in the blacks

I can use ISO3200 on the K-x with impunity....
My previous K-x shot at ISO3200 was in relatively "good" lighting -
f/4 @ 1/60, ISO3200

These were under much more trying conditions -

f/3.5 @ 1/20, ISO3200 - that's 2-stops lower/darker

and this shot:

f/4 @ 1/13, ISO3200 - which is just over 2 stops darker.....

1/13 is a shutter speed I often (have to) shoot at - but it does clearly show subject movement - sometimes undesirable - but as in this shot it is what makes it (for me) - the left front drum details show how well the SR is working too.

I do shoot JPGs - and shows how well the AWB works too - in this case I switched from strong tungsten correction in AWB to subtle correction (default, 1) because I liked the warmer tone.

This camera impresses me. K-x iso5000 DA16-45 29mm 1/25 f4 in camera NR medium converted from RAW. Some cropping and WB correction.

Pentaxor, thanks for the tips. The highkey makes the jpeg looks better as it brightens it without having to do exposure compensation. This way the shutter speed is not lowered but the scene is still brighter and thus less noise. Thank you for the tips.

But, I still prefer RAW conversion. Iso 1600 is a breeze with the k-7 jpeg, and with RAW and NR iso 3200 is very useable. I just took some quick hand held shots and compared.

Fairly low light for f2, iso 3200 and 1/15. To me the RAW conversion has more depth and reality to it, even at iso 3200.

Jpeg (normal exposure, not ETTR and pulled back)


RAW with NR


100% crops of the RAW NR image




I wonder whether K-x can give this at iso 6400 for a 1-stop advantage.

Recently needed to do quicky images for daily press releases to newspapers and websites. Shot JPEG's at the lowest resolution available in the K10d (2 megapixels I believe) and at 1600 iso. Don't know anything about noise reduction so submitted to the papers without editing other than minor cropping and perhaps a bit of exposure correction. Ended up having several images published over a weeks time by as many as 7 different newspapers (for one of the images) so extremely low quality high iso cruddy ol' JPEG's apparently aren't too bad from Pentax digital cameras. Note that I had never previously gone beyond 400 iso nor ever shot at less than max megapixels...nor had I ever done any sports photography, so the "experiment" worked!
What did you shoot that wrestling match with?

Just imagine where we'll be in 5 years!

New FF sensors @ 102,800 ISO. When is that ever even necessary!? Photos of bats?

5 years, I can do it now with my D700 and I keep reading the D3X kills the D700.

that would be the work of a night-vision camera or IR.

no problem. just keeping those K-7 owners and potential would-be owners happy and don't feel agitated by all these complaints and scary stories about ISO numbers and where the the K-7 ranks.

just let you and the camera do the talking and forget about the numbers.


RAW is definitely better. right now, I'm just out of HardDisk space and memory card space. and my RAW converters are going nuts as of the moment. dunno why.

regarding the k-x, it is better at High ISO but I would rather wait for a full-frame with a much higher ISO range. a 12800 output with an equivalent of a 400 ISO would be just great.

I meant: "FF sensors can now do 102k ISO, imagine where we'll be in 5 years!"
Poor sentence structure, my bad :ugh:
