Canon_CameraInfoR6_0x0a5d appears to be the shot number when the camera makes a focus stack. It appears to start at 1 and count up until number of images maximum is reached or infinity focus is reached. In some circumstances, camera might continue to increase focus distance past infinity.

https://cam.start.canon/en/C003/manual/html/UG-03_Shooting-1_0300.html

Canon_CameraInfoR6_0x0a5d also appears to me to increment during continuous shooting holding the shutter button down.

Canon_CameraInfoR6_0x0bb7 seems to count down when making a focus stack and after reaching zero sticks at 255

I cannot make any sense of the values when not making a focus stack

This is fascinating to me. Thank you!

Canon_CameraInfoR6_0x0a61 seems similar and increments for each image in a focus stack (depth composite) as well incrementing for each shot when the shutter button is held down

Wild guesses and speculation, not conclusions. I hope someone might see this and improve on it.

0169 - 0185 are one depth composite

0210 - 0222 are one depth composite
0227 - 0231 are the same bird with 0229 - 0231 a burst of the bird leaving the branch

SPECULATION: some of these might be related to digital level gyro
Canon_CameraInfoR6_0x042a seems to stay constant when camera is on tripod and change when camera is hand held
Canon_CameraInfoR6_0x0458 seems to stay constant when camera is on a tripod and not change when tripod is adjusted or moved but is all over the place for hand held shots
Canon_CameraInfoR6_0x0490 seems to stay mostly constant when camera is on a cheap tripod and changes when tripod is adjusted or moves and changes gradually during hand held burst shot
Canon_CameraInfoR6_0x0498 seems to stay constant when camera is on a tripod and not change when tripod is adjusted or moves and changes gradually during hand held burst shot
Canon_CameraInfoR6_0x04aa seems to stay constant when camera is on a tripod and change when tripod is adjusted or moves and change gradually during hand held burst shot

Canon_CameraInfoR6_0x04f8 seems to stay usually zero when camera is on tripod, but my cheap tripod might explain one change during a focus stack. Hand held, ususally less than 20. Wild guess is camera shake or lens shake or IBIS correction amount.

Canon_CameraInfoR6_0x04fc seems to stay constant when camera is on tripod and all over the place when hand held except sometime 2 in a row are the same during burst. Wild guess is roll relative to horizion. (maybe signed byte)

Canon_CameraInfoR6_0x0581 seems to stay the same when camera is on a tripod and changes when tripod is moved or adjusted. Wild guess is vertical tilt or maybe roll (maybe signed byte)

Canon_CameraInfoR6_0x05aa seems to stay constant when camera is on a tripod and change when tripod is adjusted or moves and changes gradually during hand held burst

Canon_CameraInfoR6_0x05d8 seems to stay constant when camera is on a tripod and not change when tripod is moved or adjusted. If unsigned byte, then changes gradually during hand held burst

Canon_CameraInfoR6_0x05ea seems to stay constant when camera is on a tripod and changes when tripod is moved or adjusted. Bigger changes during hand held burst.
3 focus stacks and one hand held with shutter held down, 0227-0228 are same bird on same branch as 0229-0231 burst as bird left branch

Previous observations do not seem to be true today.

I made several images where I changed the direction the camera was tilting.
https://www.rsok.com/~jrm/raw/tilt_test.zip
Inside the zip file is key.txt which maps image number to kind of tilt
For those labeled "level" I tried to get the electronic level on the camera screen to look nearly level

Camera was on a tripod, but it was windy and tripod might have moved.

281-283 level
284-288 up one
289 down one
290 down 2
291 down 5
292 level
293 up 5
294 level
295 tilt right
296 tilt right further
297 tilt left
298 tilt left further

Hi John,

This is really interesting work. Thanks for your efforts!

I looked at your images and data and observed this:
  • the numbers in the 6th column look like tens of degrees of pitch (up/down, like an airplane), with zero pointing straight ahead (the horizon would be in the center of the frame), increasing with camera pointing up, and decreasing down from 3600 with camera pointing down
  • 287 and 288: the camera has moved and is pointing up with respect to 284-286, which would explain the differences in the 6th column of your data (63 vs 52)
  • the numbers in the 5th column look like tens of degrees of roll (tilt, or airplane banking), with zero being level (horizon parallel to long image axis), increasing with camera rolling left (the left side of the camera is lower), and counting down from 3600 with camera rolling right

Thus, image 291 would have been taken with the camera pointing (3600-3486)=114 => 11.4° down, and rolled/tilted/banked 11 => 1.1°  to the left. I like "pitch" and "roll" because the definitions are clear (Aircraft principal axes), but I'm not sure what people use in photography.

Is this what you think is happening?
If it does, I'll repeat the experiment with my R6, including left and portrait orientations, pointing straight up (I noticed the viewfinder level isn't stable as you do this), straight down, and upside down (ceiling/floor inverted).

I've been wanting to get these values forever. I hope this works.

This is really interesting work. Thanks for your efforts!

I looked at your images and data and observed this:
  • the numbers in the 6th column look like tens of degrees of pitch (up/down, like an airplane), with zero pointing straight ahead (the horizon would be in the center of the frame), increasing with camera pointing up, and decreasing down from 3600 with camera pointing down
  • 287 and 288: the camera has moved and is pointing up with respect to 284-286, which would explain the differences in the 6th column of your data (63 vs 52)
  • the numbers in the 5th column look like tens of degrees of roll (tilt, or airplane banking), with zero being level (horizon parallel to long image axis), increasing with camera rolling left (the left side of the camera is lower), and counting down from 3600 with camera rolling right

The terminology used by Canon is at: https://snapshot.canon-asia.com/article/eng/what-you-need-to-know-about-in-body-is

I think you are likely correct. The leg on the right side of my tripod tends to slowly slip.

The Canon terminology matches the "aircraft" terminology, so that simplifies things.

I'll try with my R6 and report back here.

last 3 columns of Canon_0x4059 appear to be:
current focal length, minimum focal length, maximum focal length

For my EF-S 24mm, it is 240 for all three
For my EF100-400mm f/4.5-5.6L IS II USM +2x III it is typically 8000, 2000, 8000

Darn! My R6 doesn't have this tag. I have the latest firmware (1.8.4) and ExifTool 12.76.

Perhaps it's somewhere else, but so far I cannot find another tag with similar values. How did you find where the pitch/roll information was? Or is this tag available only with later versions of EXifTool?

[Update: I tried with the latest ExifTool (12.86), and the R6 doesn't have the Canon_0x4059 tag :( ]

Maybe with -v3 and hex dump it could be found for EOS R6

I made that series of tripod shots this morning and tried to find numbers that roughly changed with the pattern of the tilts

Maybe some of those numbers are already decoded for EOS R6 and the name Canon_0x4059 does not appear in the output. My guess is that 0x4059 is some sort of offset in hexidecimal. It appears that with -v3 there are offsets that start counting at zero and names that start at one so 58 instead of 59 is possible. There appears to me to be a hex dump of the entire makernotes section.

It does not seem to exist for my EOS 80D either.

I am using exiftool 12.86 on my iMac and 12.63 on my Debian desktop.

I'll look at it again. I used the HTMLdump option to look at the raw data.

How did you happen to find that the data was at offset 0x4059? Trial and error?

This is great, thanks.  For now I'll decode CameraInfoR6 0x0a5d as SequenceNumber, but I won't decode anything else yet.  The CameraInfoR6 is a binary data block which is more prone to model/firmware differences.

However, the Canon_0x4059 data is likely more consistent.  I will decode RollAngle, PitchAngle, FocalLength, MinFocalLength and MaxFocalLength.  Great.

The one thing you need to try is to put the camera in portrait orientation (roll = 90) then move up and down to test the yaw axis angle.

BTW. 0x4059 isn't an offset, it is the numerical ID for a tag in the TIFF-format makernote structure.
