firmware bug ? wrong colors


The pictures were taken in interval shooting mode, JPG, auto WB and vibrant. ISO 200, f2.4, 0,5". MF, DA 35mm

I uploaded 7 pictures as example, previews pictures were fine.

Has it happened to anyone?

Thanks in advance,

This last picture, where the sky turned blue has happened to me. BTW that was when I shot DNG and AWB. But yes it looks like a software glitch.

The problem is the sky being too blue in the last shots, right? Its probably Auto WB's fault. You see, the white balance of the ambient (colour temperature in K) is changing at that time. It goes from daylight, to very warm (orange) and then suddenly to very cold (blue, shadow). And AWB is trying to neutralize that for each shot! It doesn't look at previous shots to make a consistent series. It merely checks the situation and adjusts.
In those situations, switch white balance to Daylight, or make a custom white balance. Or experiment with the crazy CTE. CTE is good for sunsets, but it is also variable, so it might not be useful for interval shooting. For interval shooting, you probably want a fixed WB. Or shoot raw and adjust it manually in post.

So this is not a bug and firmware version will not affect it. Its working as it should. AWB is just the wrong choice for that concept.

Or am I misunderstanding the problem?

Edit: Here, I even googled a tutorial that mentions how important WB is for timelapse (especially in changing light):

Yes, AWB is the wrong choice entirely. Always use custom white balance for time lapse. Always.

Right, I understand now. AWB was fighting to balance the orange. It found the gray "useless" so put the orange as white and the rest in blue.

I was expecting to the auto to be magic.. my mistake. I'll take in mind to the next. Daylight would work fine.

Thank you very much for your help
