Grazie, you up yet?

After you've had your morning tea, can you run a small test for me?

I need to know if your iPhone 4 is shooting 0-255 in full light. Take it outside (if the sun is shining in England today) and shoot some scene with deep shadows and bright whites, and throw it on the Vegas histogram.

I'm sure Nick would like to know too. If you are able, could you upload 30 sec. of native iPhone 4 footage somewhere?

Thanks for all you do.

I'm up.

It's overcast.

What now?

London 10:00am.

Yup, according to SONY Vegas Histo Luminance Scope I'm getting full 0 > 255 . No clamping.

Just did some footage of brilliant white painted stonework windowsills and flowers siting in troughs with deep shadows.

Does this tell you anything?

Regards

Grazie

FWIW, also my Samsung Galaxy II records FHD in the full 0-255 range...

I'm collating results for as many devices as possible in the first post of this thread. I added iPhone 4 and Samsung Galaxy II.

Thanks Grazie!

Would love to play with some sample footage if you have time to upload somewhere (Mediafire, Dropbox, etc.)
