Re: Guess the iso.

I have just been experimenting with mine and now I would like to change my guess to ISO 10,000.

Sample available on request.

Re: Guess the iso.

Assuming the correct answer has not been given, I plump for 12800 assuming there was no crop and just a resize to shed pixels.

Re: Guess the iso.

Paul and Ross guessed correctly, this is an iso 6400 image.

As I mentioned, the image was processed in LR, not cropped but resized to upload to the gallery.

I think this shows that the E-M1 II can produce pretty good images at high iso, Im sure this would produce a perfectly acceptable print.

Thanks to everyone who participated.

You don't need a Mark ii for high ISO, this was shot at ISO 6400 on my E-M5




The trick is not to under expose, not even a little bit. As a general rule for high ISO, Expose To The Right (ETTR) using the histogram.

Re: Guess the iso.

This has been an excellent thread teasing out lots of useful info. I'm definitely going to be a bit more adventurous with my iso levels from now on.

Ditto.....

I am certainly very cautious about going into even 4 figure/number ISO's. Maybe have to slightly over expose as said above.....

Re: Guess the iso.

Which raises an interesting question. Is it better to set the camera to, say, ISO 1600 and under-expose, or 3200 and over-expose with the same aperture and shutter speed?

That's a very good image at such a high iso.

As you say, ETTR seems to be the way to go.

I'm certainly going to continue to experiment with the use of high iso and how to correctly ETTR using the histogram.

Here's a link to a video which explains the use of high iso and ETTR on Olympus cameras:

I hope this will be of interest to Forum members.

Absolutely none. It was taken in RAW. No in-camera noise reduction and then loaded into Lightroom. From Lightroom I simply exported it as a jpg with long side set at 1024pix at 72ppi.

Like you, I shoot in raw and don't use in camera noise reduction however, I do use it when editing in LR.
