Darks with shutter closed

[dts350z]

Since Canons can do in camera noise reduction, essentially taking darks with the shutter closed, is it possible to do that via the SDK?

 

That would allow for unattended darks to be mixed in or at the end of a capture plan.

 

I was thinking about doing that with my filter wheel, except a) the wheel can't currently be controlled from the capture plan, and I'm going to use all the slots anyway <_<.

 

But being able to close the shutter AND take darks would be awesome.

Done. Shutterless dark frame control via the SDK requested.

Anyway, if we don't ask Canon, they will never implement it. If we ask, they could maybe think about it... or not.

 

Bug reports or new feature requests for the Canon Digital Camera SDKs should be submitted via e-mail to:

Shame, this would have been a useful feature, effectively allowing one to sequentially program BYEOS to take Lights followed by Darks and then BIAS all in one run with the same temperature etc...

Bias frames are not temperature dependent, so they can be taken and used for images shot with that camera at different temperatures for several months.

 

Personally I don't use bias frames during image calibration. I use darks and dark flats, so Bias frames are not necessary.

Yes true, but I take everything at the same temperature anyway and then pack it all up. Still, it would have been nice to have access to this feature to plan an uninterrupted run of different types of frames.

In "The Old Days", the explanation from the DSLR Manufacturers was "A DSLR doesn't take any Exposures without Activating the Shutter; so why add it to the SDK".

 

However, as the addition of LENR (Long-Exposure Noise Reduction) has permeated to all but the lowest of Entry-level DSLRs, they DO now have (at least internally) the ability to take In-Camera Darks - Exposures with the Shutter Closed.

 

So, it would be hopeful (and helpful) if they (the DSLR Manufacturers) would start to expose (pun intended) that Feature in their SDK offerings.

(One can only hope...)

No, this is not possible sadly.

Bummer.

 

Do you have input into future features in the SDK?

 

If so this would seem like a good one.

I have 0 input... and I doubt that Canon will add this functionality <_>
