Thanks Milton.

I’m not blaming Astro IIDC .. I know Sony is less than good at helping developers..

All I can add is that Sony sucks for following the IIDC specification and they were involved with it from the start of the IIDC spec's evolution.

They do "custom register things" and since I had no Sony cameras for testing, I could not track track down how they behave. Many of these were specific to a single model too and since the model names are not part of their specification documents, I can't tell what are or how to custom code it. Also, I should not have to write skanky code to account for single models of cameras either.

For example Sony cameras in > 8 bit modes didn't up shift the data to be a full 16 bit value, they padded it with zeros and left it unchanged. So if it was a 10 bit camera (1024 shades), they packed it into a 16 bit value (capable of holding 65,535 shades) but left it as 0 to 1024, not 0 to 65535. So your image would be 64 times darker than it should be. No one else does that and the spec specifically says to make it a expanded 16 bit value. That's why I had to add custom code to handle that, which you have to turn on in the preferences. They also did not indicate what the camera bit depth was either (which was provided for in the IIDC spec), so you have to manually do so your self via trail and error.

PGR was exceptionally good at documenting these sorts of behaviours and following the specification - Sony doesn't. TIS wasn't real good at it either.

HTH..

Here is what I've tested so far :

Astro IIDC : Works 100%, tested with the following cameras :

PGR Flea2G (FL2G-13S2M-C) including long exposure

PGR Flea2 (FL2-08S2M-C) including long exposure

PGR Scorpion (SCOR-20SO) including long exposure

PGR FireFly MV (FMVU-03MTM-CS) (USB2).

TIS DMK 21AF04.AS including long exposure

TIS DFK 21F04

Sony XCD-U100CR (need initialisation via another app or Astro IIDC crashes)

All the FireWire cameras were tested on the onboard FireWire port as well as on the Thunderbolt to FireWire adapter.
