make_arq's Issues

Lack of support for the A7R IV A variant

Since make_arq is able to handle frames produced by the A7R IV camera, it should also be able to handle its "A" variant, but it currently rejects the ARW files.

Request for Q&A.

Dear Agriggio,

First of all, thank you for creating the make_arq code repository. I have a question to ask you. I have a Sony A7RIV camera that can shoot Pixel Shift images. For one scene, I can get 4 ARW files and one ARQ file. I found that the ARW files are 6376×9568 in size, while the ARQ file is 6376×9568×4. I believe that the ARQ file contains one R channel, one B channel, and two G channels. How can I get a demosaiced image with three channels?

Best regards,

recently only quater image for a7r4

I have tested three versions of make_arq:

1. installed on Nov 25 2020
2. installed on Feb 9 2023
3. installed on May 18 2023
   on two (old and new) gentoo distributions.

old (2020):
python-3.7.8-r2
tifffile 2020.11.18
glibc-2.31-r6

new (2023):
python-3.9.16_p3 (can be switched to version python-3.10.11)
tifffile 2023.4.12
glibc-2.37-r2

<tifffile.TiffWriter 'out16-new-2.ARQ'> not writing extratag 258

Recent version of make_arq displays only quater image.
Only oldest make_arg on old gentoo displays full image.

Error when trying to combine 4x or 16x pixelshift from A7R4

When combining 4 or 16 images from an R4 I get the following message:
KeyError: 1.25

I removed the try/catch block and got a stack trace:

Traceback (most recent call last):
  File "/home/alexander/media/sw/make_arq/make_arq.py", line 218, in <module>
    main()
  File "/home/alexander/media/sw/make_arq/make_arq.py", line 205, in main
    frames, width, height = get_frames(opts.frames)

  File "/home/alexander/media/sw/make_arq/make_arq.py", line 132, in key
    g = seq2idx[1 + sn / 4]
KeyError: 1.25

I tried different methods to call the program, made no difference:

make_arq.py -o out.arq AR400274.ARW AR400275.ARW AR400276.ARW  AR400277.ARW
make_arq.py AR400274.ARW AR400275.ARW AR400276.ARW  AR400277.ARW -o out.arq
make_arq.py *ARW -o out.arq

I'm using Debian testing (bullseye).

python 3.9, 3.10 - green image

Using python 3.9 or 3.10 images are green
(something like demosaicing none on page

).

With python 3.7 all looks good.

Support for GFX100s

Hi Albert, I don't believe this supports the GFX100s which should be very similar to the GFX100 files. I tried to make it work by modifying the accepted camera models and it generated an ARQ output file which didn't seem to work. Beyond my skill. Hoping support for GFX100s could be added. :)

Support for Sony Alpha 1

I tried to use this for images taken with a Sony Alpha 1 and it told me it can't do that. I took a couple of example pictures, both with full frame and with APSC-crop, both with 4x and with 16x (uploading should be done in an hour):

The Alpha 7R V has the exact same sensor resolution as the 7R IV so that would probably work by just treating it the same, but I don't have examples.
