batch convert dngs to tiff

[olik]

Is there a way to batch convert dng-sequences to tiffs? So that we do not have to convert shot by shot?

[notdabod]

Select all dng's, right click, open with PS,

Hey folks,

is there an easy way to batch convert DNGs to TIFF? With Photoshop I can only convert one file at a time. Maybe with AFX?

best regards

O.

EDIT: sorry I was not clear, I meant and easy way to batch-convert the DNG sequences (not individual frames).

Adobe Camera Raw can batch convert.  Select all images in Bridge and open with ACR.  Select all images in ACR and save images.

sorry, I was maybe not clear enough. I meant with Photoshop I can only convert all the DNGs from one clip in one go. But what if I want to convert all the clips that I might have in separated folders?

Then you need something like after effects. RawTherapee does batches but it's a bit buggy on the mac.

Oops, sorry; you want tiffs, not DNGs.
Why would you want tiffs, if I may ask?
for editing purposes I use the (raw) DNG sequences, not the (converted to 16bit and MUCH larger!) tiffs.

Dcraw will export 16bit Tiffs, you have control over the raw development to start with plus choice of colorspace such as Prophoto, XYZ, AdobeRGB, sRGB or undefined RGB, you have cotrol over WB and gamma, so if you don't have access to raw handling in an editing / grading app 16bit Tiff is one route baking in WB etc but retaining some space (16bit per channel levels) for 'grading'.

Big problem is at 1080P that's 12.8mb per frame. :-)

How do you edit with the DNG sequences? As far as I know, nether FCP nor premiere (or resolve) can import those. You would need to convert it to sth else. As I worked with Photoshop until now to convert my DNGs I choose 16bit tiffs as it seamed a better option for grading than jpgs. I am rendering now with AFX a prores444 of all my dng sequences. But if I could edit the dngs sequences, that would be fantasitic!

I think he was referring to how to automate the process, if there is a lot of folders with DNG. That's a good question, a very vital. Because the test shooting 3-4 plans is one thing, but when they are 100-200, etc. Automation is very relevant question. Who has ideas? (sorry for my English, I write through translator)

For windows ... Download dcraw http://www.heliconsoft.com/heliconsoft-products/dcraw/

Add this line to a batch file for the most basic conversion. Execute in the directory you want to make .tiff files.
for /f "usebackq delims=|" %%f in (`dir /b "%CD%\*.dng"`) do dcraw -v -r 2.132483 1.000000 1.480864 1 -H 2 -T -b 3.5 -4 %%f

For .RAW to tiff Make a batch file and add the spoiler below. Should give you even basic white balance.
