Malfunction of Sequoia

I have recently started working with Sequoia. I have connected sunshine sensor and camera together and then controlled them via wifi.
For each shot, I got 5 pictures but only RGB one was normal, the rest four ones were mostly black. This happened for every shot! .
Anyone met this problem. Please help me.

Hi @Dongpham

The other four images that seem black are TIFF files coded on 16 bits
Windows thumbnails doesn’t work properly for these.
Try to use ImageJ and please feedback the community
