Hi happy new year to everyone, could any one tell me how to to change CR2 files to tiff files, as a batch because at the moment I'm having to do them singularly and it's a PITA and also how to change them back to CR2's or jpegs
cheers andy
 
What software are you using?

In Lightroom... just select them all and export them all with whatever settings you require. It's usually the case for pretty much everything else I've used. Select the ones I want, then export them. Lightroom, Capture One etc... will all export the ones you've selected as a batch.


You can't "change" them back into RAW files once converted. The idea is, you export them as a copy in another format (TIFF, JPEG.. whatever), and retain your RAW( CR2) files... these are you "negatives"... why would you want to actually change them into another format?

The canon software, Digital Photo Proffessional that came with the camera will allow you to batch process selected files from RAW to TIFF or JPEG.
 
In answer to your question, David I've been trying to run them through deep sky stacker it says that it does CR2's but when i run them through the program it brings the stacked image out as a portrait with only half the image on it, but if i do them as tiff's it does them in landscape with the whole of the image so I've been converting them one by one which is long and boring but then I want to change them back after i've messed about with them ( won't say processing ,not very good at it).
anyhow thank you for replying and you also coldpenquin
 
Ah, I had a similar issue, images rotaed 90 degrees and only half of it coming out, and then im magenta cast.
The software was too old to understand the CR2 format that the 7d used. It seems Canon re-use CR2 for all Canon Raws, even if they change the format for later cameras. (I assume at some point there was a CR1 or something though).
 
All manufacturers do this. All Nikons use .NEF but newer cameras will not be supported by older software. It's not just Canon.
 
I made them into Jpegs and they work out ok, but turns them into tiffs when DSS stacks them, which it supposed to do so how do i turn them back to jpegs
 
Don't turn them into JPEGS!! JPEGs are a compressed, lossy format. Each successive JPEG save lowers quality. If you want the finished product as JPEG then do so after DSS has finished. You're compressing them as JPEGs (losing quality) then DSS is converting them back into TIFFs... then you want to recompress them again as JPEGs?

Start with TIFF... let DSS work on them as TIFFs... then save a COPY as a JPEG if you need it for online or screen viewing, but retain the TIFF as your master copy.

And remember.... every time you open a JPEG, and resave the same file as a JPEG, you are lowering quality... just like copying an old analogue cassette tape.. each generation will sound worse than the previous one.
 
that's what i was doing , I was shooting them in raw and then turning them into tiffs but I can only do this singulary which is a long and laborious job when you have a lot of frames, that's why i asked if the could be done as a batch
 
Had a good look at my p/shop setting & i can import as a batch ( not tried it yet) but did try it with DPP and it worked so once again thanks for your help
