HDR and Dual ISO Postprocessing / Strange DNG
July 25, 2018, 06:23:45 PM
I tried to convert cr2 100/1600 to DNG with Barracuda GUI or simple dropping cr2 to cr2hdr.exe. I have got dng, but there is a very small difference from cr2 taken without dual iso

cr2 taken without dual iso (crop)



dual-iso-dng (crop)



dual-iso-cr2 (crop)

Now there is a good option to set Focus box for good framing in crop mode.
"Pref\Focus Box settings\Snap points - Centre to x5RAW@. It works good, but  this point is too far from sensor's centre.
The another good point is closer to the centre - 5 steps to the right plus 3 steps down. Is it possible to change Snap points - Centre to x5RAW to this point?
Thanks very much to all developers.

I've bought new Canon 70-200,2.8 L IS II USM and notice that focus point goes back if I change focus length from 200mm to 70mm.  I decided to increase a bit a distance from camera to the lens.
  Start on the back. Unscrew four bigger screws. Insert  thin metal sheets between bayonet joint and lens body near each screw. In my case it was thin metal sheet from beer can. It thickness was 130mkm.Then screw these screws. Now my Canon 70-200,2.8 L IS II USM is perfectly parfocal.

I have tested Canon 24-105 on 5D3 and EOS-M. The result is very strange.

  • Left picture - Focus length -105mm, manually focused at zoom10 and Varavon viewfinder 3x
  • Centre picture - focus length was changed  to 24mm without focus adjustment.
  • Right picture- after adjustment

What is the reason?

Raw Video / Whats up @ 42GB?
September 13, 2013, 08:06:07 AM
Toshiba 1066x 64GB cards. 5D3, 1920x1080 zebra off. ML on Aug 21 and Built on: 2013-09-13 03:10:47 +0400 the same. At 41946MB rate goes to 0, but DNG files are good.

Zebra on. At 42001MB rate goes to 0.1 MB/s
When raw file size reaches 45GB-47GB drop frame takes place and recording stops (Frame skipping -off in ML). If I stop recording at 43GB and immediately start next one, it records until the card fill. ML on Aug 21 and Built on: 2013-09-13 03:10:47 +0400 the same..

Raw Video / What is file size limit for raw video?
September 10, 2013, 11:58:48 AM
I use Toshiba 1066x 64GB cards. 5D3, 1920x1080. When raw file size reaches 43GB buffers start overflow and recording rate goes down. When raw file size reaches 47GB drop frame takes place and recording stops (Frame skipping -off in ML). If I stop recording at 43GB and immediately start next one, it records until the card fill. ML on Aug 21.
