Magenta shift at ISO100 shutter 1/8

360HDRi — Mon, 22 Oct 2018 14:44:51 GMT

Is anyone else experiencing this?

I take bracketed exposure 360 degree images. I've noticed that at shutter 1/8 ISO100, I get a nasty magenta wash over the image.

Looking back, all my pics since I purchased my ILCE-6300 have that problem. I want to check with the community to see if I'm the only one.

Best is to set your ISO to 100.

Set your shutter to continuous, 1/8 with brackets 3 shots 1 EV apart. (This will generate 3 captures: 1/4, 1/8, and 1/15).

Get a fairly dark exposure (under expose) since that's where it's most visible.

Open ARW in adobe camera raw and boost exposure +5.

As you can see in the image below, the picture with shutter 1/8 is not good. Am I alone?

Hello @360HDRi,

is it just the preview image or does it still look magenta after you open it up in another software?

Hi @IamNic,

All softwares. Photoshop, Bridge, PT-GUI, IMF_Disp, XnView, RV, etc... It's more or less apparent depending on how each software handles thumbnails. My process usually involves 16bit conversion in dcraw, followed by a 32bit conversion in either photoshop or Nuke. The problem is already noticeable on the raw file with the simple expo boost in ACR. I've used a different lens and was easily able to reproduce.
