Save RAW files in DNG format instead of RAW

quietschi

tried many different settings of the OSD Menu and Canon Original OSD (with DISP Button press), but there is nothing to see.
I have to say that on my camera when i take a picture the screen gets black for a short time and then comes back to normal Display. but no Information about saving time (shoot be where the scripts are visible?)

I get same behaviour on ixus70-101b, the 'black screen after shooting' does not appear to be
influenced by the review time setting. I just switched off the option.
Same on A620, except here, after the black screen i can 'see' the info for a fraction of a
second in the left bottom corner - not long enough to read it, or even be sure ...

It might be better to write this info to a log file if more cams react like this ?

Same here. Information only sticks around for a fraction of a second.

Shooting in continous mode makes it stay, though, and reveals saving times of about 970ms for CHDK RAW, and 2000ms for DNG. 😁

Script can help here:

shoot
end

quietschi

thanks ewavr - tested with script
saving time
DNG with buffer 1660ms
DNG no buffer 2690ms
RAW 710ms

@hacki
you are right in continious mode it works

@whim
maybe its better to include this function as a kind of benchmark in debug

btw about the extensions:
GNU Canon Camera Utilities
last paragraph. it seems to be possible to "hack" into the wia driver to be able to display all kinds of files.

the problem is the transfer to the pc via usb. as far as i understood ewavr, he is already working on that part, by replacing a normally unused extension with dng.

For A710 this problem is solved (DNG instead of DPS+THM).
Maybe for many cameras DPS is impossible extension, but can be implemented "DNG instead of CR2".
If someone wants to test this feature, I'll make test version (please specify camera name and firmware version, DRYOS is preferred).

i guess dps is available on every camera with a print button?

I'd be willing to test. Cam specs below;

Canon Powershot S5 IS
Firmware: 1.01b
OS: DryOS

In A710 (for example) camera firmware uses *.DPS file name mask to search files at USB connection in A/DCIM/nnnCANON folders (*.CR2 mask absent).
In SX100IS(for example) no *.DPS mask present (only filenames like DDISCVRY.DPS, DRSPONSE.DPS etc), but *.CR2 mask present.
In other cameras (for example, A570) both *.DPS and *.CR2 masks are present.
We cannot add new mask (because these masks stored in ROM), but can change any of exitsting mask to other (because some function which uses this masks called only by pointer stored in RAM).

Extension can be changed to DNG in RAW menu.
Don't forget turn off / turn on camera after shooting and before PC connection. Use Windows explorer (I don't know how it works with other software).

Okay, here's the scoop;

When I set it to .DNG for the extension it worked flawlessly. Both single and conitnuous worked fine and output DNG files with the file name CRW_####.DNG. And the files can be opened fine too after transfer.

Transferring: Works fine in reader (cut and paste), but when connected to cable, only the jpeg is seen and copied both from the canon transfer agent on my computer and when looking at the files in the scanners and cameras media file, I only see the jpeg.

I always use my reader for transferring, but thought I'd try the other as well. It all works fine, but the transfer through the USB cable is a bit iffy.

My report:
A720IS.

With the crw extension the dng raw files are transfered together with the jpegs using the usb and the camera window transfer tool by Canon.
Camera Window doesn't show the dng raw files, just the jpegs and avi, but the raw files are transfered to the PC.

And the dng raw files (with crw extension) are loaded ok with all my softwares: photoshop, rawtherapee, xnview... And I can work ok with them.

I really don't see the need to change the extensions to DNG.
I'm using windows XP.

binsurf

At the very least, it would be convenient to have the option to change the extension to .dng.

Mine didn't transfer with the jpegs at all.

vit40

Well, I think many of us are using card readers, instead of crappy camera interface to transfer files, so problems with file extension are unimportant for us ... so it would be fine to have an option to name files as .dng

@binsurf

Are you storing the raw in the same folder with jpegs?

laetilodie

I had .DNG in the firmware to try with my S2is and when DNG are or are not store in the same folder with jpegs only the jpeg is seen and copied both from the canon transfer agent on my computer and when looking at the files in the scanners and cameras media file, I only see the jpeg.

Yes, I am.

Will this be added to the main trunk soon?

I have a problem with "show_bad_b.exe", it seems to always give "Total: 6069.".
I've just tested on 3 raw-files, one 1sec, one 10sec and one 64sec exposure.

All three badpixel.bin's is identical and 24276 bytes big.

Is there some bug in this program, or do i have way to many bad pixels?

Edit:
Just tested with shorter exposure, then it seems to work.
