I was using my other system yesterday, which has Windows 8, and it must have been blocking the link? Hmmm. Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted December 17, 2012 Administrators Share Posted December 17, 2012 The ISO test is insane, but you have to wonder if the lighting was turned down of if the NDs, aperture or shutter was changed to compensate for the ISO increases. Because an ISO test under strong studio lights is the height of bunk. richg101 and Sean Cunningham 2 Link to comment Share on other sites More sharing options...
hmcindie Posted December 18, 2012 Share Posted December 18, 2012 DPreview studio testing for stills is done under studio lights and only changing shutter. I do not consider the results bunk. Link to comment Share on other sites More sharing options...

Sean Cunningham Posted December 19, 2012 Share Posted December 19, 2012 I can't speak for Andrew but, to me, it obviously doesn't represent a real world use for high ISO in the context of the DSLR filmmaker. Shuttering for exposure is also quite inappropriate. For a stills photographer, fine. Not for DPs. Link to comment Share on other sites More sharing options...
FilmMan Posted December 19, 2012 Author Share Posted December 19, 2012 Here's the score: Shane used a light meter to keep the exposure consistent through every Iso. Keeping the shutter angle the same, but dialing down the lighting, and T-stop on the lens to compensate for the increased sensitivity in the higher Iso’s. It was a good test in my books. Cheers.

Administrators Andrew Reid Posted December 19, 2012 Administrators Share Posted December 19, 2012 The clue is in the term 'LOW light'. You need to test CMOS sensors in situations of under exposure and dim lighting. A well exposed area of the image is much cleaner at, say ISO 12,800, than a shadow area. If the whole frame is well exposed with no shadows, and under strong studio lights, the results aren't accurate. You can see with the GH2... Set it to ISO 3200 and operate it in day light. Clean as a whistle. Link to comment Share on other sites More sharing options...
lafilm Posted December 19, 2012 Share Posted December 19, 2012 Great example. What needs to be understood is how if you're creating a project where the material calls for nighttime/low light...these Canon cameras can save you a ton of money.
