from noob: how do I convert mass files from pef to jpeg?

bman577 · 07-26-2009, 05:38 PM

I have gimp, photoshop cs 4, lightroom, and elements. I know minimal about all of them. I need to convert about 45 files that I took as PEF in my camera, by mistake, and I want to convert them all in one swoop to jpegs. Is there any easy way to do this or do I need to open one photo at a time and convert it?
Thanks

It might not be the fastest option, but you could import them in Lightroom, then select them all and export together?

Yep, bringing them into Lightroom and then exporting en masse would be your best option.

However, if you have — and are using — Lightroom, then I would suggest that you shoot in raw all the time, and manage your photos entirely in Lightroom. The workflow benefits are tremendous, and Lightroom is designed to work specifically with raw files. The only time I ever create a JPEG is for making a copy of a master image, either for printing or emailing. My master images stay in raw.

Yes,

Use the software that came with camera, 'Pentax Photo browser', do a select all and right click and "extract jpg".

i have found that the software for pentax cameras to be quite buggy well atleast the version that came with the k100d super any way.

personally i use raw therapee to convert pef files and allows batch processing too RawTherapee V2.4 released
silkypix kept crashing every time i tried to batch .

Photoshop's Camera Raw is just as good.
Open all your RAW files together, specifying that they open with PS, and they all appear on Camera Raw, usually automatically 'optimised' according to what PS thinks is best.

Select All and Save, and you have JPEGs converted.

PS is inefficient at mass raw management

i suggest using lightroom, just make sure you edit them before you export

and remember how you are exporting, play with the settings, jpeg quality and resolutions.

Import the images into Lightroom
[G] or select Grid mode
[Ctrl]-A to select all 45 images
Click the [Export] button and choose "Burn fill size jpegs" and select the folder to put them in.
Unless you want to put them on a CD, just cancel the burn when prompted after all the images have been exported.

Download/install Irfanview, install the Formats - (version 4.23) plugin package(I think it's part of the big plugins pack, so if you have the time you could also just install that). It's free, fast, and will batch convert PEFs/DNgs to darn near anything. And it avoids all the nonsense with importing into Lightroom just to convert them.

In Bridge (PS4) > Select Folder (files) > Tools > Photoshop > Image Processor. You'll get this menu:

From here you can then either open the first image of the group and set the size and compression factor, or simply input the info in the menu, run the processor and have them all converted to jpeg and saved to a folder of your choosing. It will two, twenty or 200 quickly and easily without any hassles... and it leave the original PEF files alone. Stay away from the "batch" option, it gums up the works,

As FHPhotographer says, also works for CS3.

i use ufraw-batch for that. something like
ufraw-batch --curve=linear --out-type=jpeg --out-path=destination-dir/ /directory/where/pefs/are/*.pef

that's about as simple as it gets, and usually works great. this is part of ufraw UFRaw - Home, available for linux/mac/windows, whichever you prefer (standalone and also as a gimp plugin, as you said you are using gimp)

you probably solved your problem long time ago already, but in case somebody else will be looking for their own answer

One more option; FastStone Image Viewer also has a batch convert option

I used to use Irfvanview, but have changed to FastStone. Irfanview strips the exif from RAW files.
