Guide: "Calibrating" Boson lens without hardware blackbody

[tske]

It sounds impossible, but I just successfully did it using a Seek lens (cheap and easy to get, good wide FOV).

Steps:
1. Export existing calibration data from your Boson.
  a. Connect your Boson to PC controller software.
  b. Start lens calibration procedure, then abort when it ask for blackbody.
  c. The original calibration file is now at C:\temp\bosonxxx\xxx.tiff
2. Use a picture editing software you like (eg. GIMP), to stretch or squeeze the histogram depending on your need, linearly.
3. Save the file as a 16-bit integer TIFF file, without any additional data (EXIF/layers, etc).
4. Use a Hex editor, replace the start and end of file using attached demo TIFFs. I made them easy to recognize, by making all pixel data "FF" (white).
5. A correct file should have the same size as my demo TIFFs.
6. Upload your finished file to camera using the same controller software.
7. Check live view results, if not perfect, repeat previous steps until satisfied.

Notes: If GUI crashes during uploading, it means your file is rejected, carefully check step 4.
Or try to upload my demo file directly, if still fails, you don't have compatible GUI and camera version.

You can skip step 1, and instead using calibration files on this forum, or "archive.org".
