Nikon Patch 1.20.4

Postby Simeon » Mon May 04, 2015 8:29 pm

I have just pushed version 1.20.4 of the online patch tool

This patch includes the "True Dark Current - Menu based" for the D800 1.10 & D7000 1.03 firmware releases. This item replaces the "Color Space Setting" menu item.

Also for the D7000 1.03 is the "Variable Frame Rate" patch, this replaces the "Max continuous release" menu item. Presently I've not merged some private 50 fps patches, so the movie recording will be limited to sub 30 fps. Once the 50 fps patches are blended, you be able to get 45 fps.

Great work from astronomer here.

Several known issues and feature with variable frame rate:

1. Like the dark current, it is only transient. Power off or metering sleep will reset. Just reactivate it using the menu. Or setting the auto meter off to a longer value.
(Fixed in next version)
3. At low FPS, below 12FPS, the shutter speed is no longer accurate due to avoidance of overflow issue with register and need to lengthening the line time instead of frame time. And each original 1EV is now 2.848 (sqrt(8)) base, no longer two. Shutter speed will cover from almost 360° at 1/30s to minimal of 1 line time at 1/8000.
4. Playback will still be at 30FPS, like a time lapse.
5. Valid setting range is 3~90, check in camera help under English. The function is only affecting 30FPS movie sets (720p30 and 484p30).
6. Sound recording should be turned off because sound is no longer synchronized.

Hi,

I am not sure if the dark current tool is working correctly or if I do something wrong. I patched the firmware, and set the meter to unlimited time. In the menu there is an astrophotography page which shows "size priority" and "sensor raw on." I chose either of them and tried taking a very short exposure when the camera is covered. In both cases, the images have the same pink tint. However, the pink tint is not as bright as it was when I used the USB hack (a version I got in early Sep 2014). On the other hand, in both cases, it is not perfectly dark either. Only after I power off the camera and turn it back on, the image is perfectly dark.

Is this correct?

Cheers,
Wei-Hao

Thank you. Then I can confirm it works properly on my D800.

Here are two other questions. First, is there any difference between the two options
under astrophotography ("size priority" and "sensor raw on" )?

Also, is the only difference between the new RAW and the old one the bias level?
If so, I can still mix the new and old dark and flat images if I subtract their associated
bias first.

Cheers,
Wei-Hao
