Hi, 

 

Not sure if this is specific to Mac but I've just downloaded the latest version of APP and my flat frames are coming out green. I check on previous sessions flat files at they are also turning up green. I'm quite new to the software so feel I may have missed something?

 

Thanks,

Vincent

Most likely due to the RGGB matrix of the sensor and the two green pixels dominating, as seen in the histogram too. I can't recall if mine look like that but a green cast is quite normal I'd say.

@wenxin As explained by Martin this indeed is perfectly normal. APP by default debayers the raw images which is why they show up in color.

@scotty38 and @wvreeven thanks for your replies both.  Weird that it only started doing it now. it always showed a normal flat frame before. Thanks!!
