Pentax k-5 raw: dng or pef?

Hi there,
I used to shoot raw (=pef) with my Pentax K-5 and import/process with Aperture (3.4.5=current).
Just out of curiosity I changed to DNG format in the Pentax. When those raw shots are imported and processed, the color correction is SIGNIFICANTLY different from the one for PEF raw shots (much darker, more contrast). Anyone noticed something similar? WIthout checking with color test cards or the like, I'd say pef get treated correctly/better than dng...

I think you've just about answered your own question. Go back to PEF!
I'm using Sony cameras now but shot with Pentax for several years. During that time I too experimented with in-camera DNG. At first, it seemed like a great idea — one universal format that future-proofed my raw files. Well, it didn't turn out that way. For one thing, the big camera makers (Canon, Nikon, Sony) don't support DNG: they use their own proprietary formats and will continue to do so for the forseeable future. But the less common formats (like PEF) are still supported by all raw converters like Aperture and Lightroom. DNG files caused me way more problems than PEF ever did. Some of the programs I worked with at that time (Bibble Pro comes to mind) didn't even support DNG, for reasons that they defended on their website. And I too had the experience you've had, of DNG files being rendered a bit differently. I thought that wasn't supposed to happen but it did.
Now I save my Sony .ARW files. I have no intention of converting them to DNG in the future. My sense is that, with no major camera manufacturer supporting DNG, it's really got no future.
Good luck.

How do I process raw .dng or .pef from pentax k20d into .tiff 's (or jpegs) in aperture 3?

hi all my friends!
how do I process raw .dng or .pef from a pentax k20d into tiffs or jpegs in aperture 3? (i have the trial only but will buy a3 if i actually can learn how to use it in 30 days...which i've failed so far)... the raw files are taking up too much space on my HDD. i understand how to change the colors, sharpness etc of the raw files. but how do i actually turn raw files into a tiff or jpeg to just keep in the library in aperture? i have no intention of keeping the raw's.. I just shoot raw to get better jpeg or tiff results.
also I would greatly appreciate some tips how to do this in batches fast and easy. I have yet to yield images so good i will actually want to spend time perfecting them. for now i just want an easy way to turn raw files into tiffs or jpegs with some standard or completely auto mode. i can do it in camera but it is time consuming.
and you cant convert raw to jpeg or tiff in iphoto, right?
best regards, Joakim
p.s. and thank you who will answer this...i can't find the answer anywhere...tried for a whole day... d.s.

do you know if the raw files are some way made more compact when you shut down aperture? cause i mean, +20MB for a pic is a lot of space on the hard drive vs. 5MB for a jpeg or so...of course keeping your raws would be the optimum if they simply don't take that much more space than a jpeg... how does aperture do it? are the files "zipped" when not in use?
No, the size of the files doesn't change, Aperture doesn't compress or otherwise alter the masters.
and in either case, can you put the aperture archive/library somewhere else than on your local HD, like a portable 1 TB HD? mine is only 250 Gb or so and running low...
This is doable and most people running on laptops use this method in one form or another. The best results are obtained by keeping the library on the internal HD but storing the masters on an external HD. The masters in this case are referred to as 'referenced' (when the masters are in the actual Aperture library they are referred to as 'managed' )
By putting the masters on an external disk but keeping the library on the internal you get the best of both worlds, reduced internal disk consumption and better speed accessing the Aperture library. If the library itself was on the external HD, especially if it was USB, you could notice decreased performance.
There has been much written about this type of setup here in the discussions. Searching the list here should get many articles discussing this topic with lots of very good advice. Also spend some tim with the User manual, Apple did a good job with it and the fist few sections really explain the various bits of the library and the different ways to set it up.
As i wrote in my first question, is there an easy way to adjust the values of a 100 raw files automatically?
To adjust a large number of images try this: Select one image and adjust it as you like. Then select Metadata->Lift Adjustments, a HUD will open. Now select the other 99 images and in the HUD that opened select Stamp Selected Images, all those 99 images will now have the adjustments you applied to the first image.
Again this is all covered in the manual.
Good luck

Help, Help me Rhonda! (Pentax K-x RAW)

Is ANYONE getting usable results from current Aperture and OSX versions using a Pentax K-x and RAW files?
I have tried everything I can think of, and still getting huge color shifts on high ISO (1600 and above) RAW files.
If this is working for you, I would love to know EXACTLY what versions of CRU, OSX, and in-camera settings you are using.
Thanks!
Would love to start using Aperture again, I have had to remove it completely from my workflow, and it's killing my productivity.

Thanks acai, am aware of the other posts, and have contributed to, or even started many of them.
My concern is that this continues to happen update after update, and am curious if Anyone is getting acceptable results from Aperture 3 with this camera.
If they are, it would be helpful to know EXACTLY what settings they are using, and further, it would potentially indicate a problem specific to my computer.
To date I have:
removed and reinstalled all prokit updates.
removed and reinstalled all RAW update series, checking at each update level, for each version of prokit update.
shot images in both DNG and PEF formats.
shot in all available color spaces.
shot images at ALL apertures and ISO's for import as RAW and JPG.
shot with camera settings adjusted at neutral, and many various exposure compensations
discarded and rebuilt all thumbnails many times.
forced re-rendering of previews for all Pentax RAW files many times.
individually "updated" Pentax RAW rendering in HUD on over a hundred images.
rebuilt library three times, repaired library 5 times.
created new accounts in OSX.
created new libraries for Aperture 3.
have reinstalled 10.6 from disks, and upgraded from combo update to current twice.
My most current use of Update 3.0 did NOT solve the problem under OS 10.6.6, with Aperture 3.1.1.
So again, a request for comments from anyone who IS getting this camera to work in OS 10.6.5 or 10.6.6 would be greatly appreciated.
Thanks!

How to get Aperture and iPhoto to use Pentax *ist DL RAW images natively

Using some techniques that I found in various places in these forums, I am going to give step-by-step instructions to get Aperture and iPhoto to recognize Pentax *ist DL RAW images natively.
Note: This worked for me using 10.4.6 with the latest iPhoto 06 and Aperture updates. I do NOT know if this will work on older versions of OS X, iPhoto, or Aperture.
Note: If you also use a Pentax *ist DS camera, these instructions will probably disable support for that particular device due to the modifications made to a system file. Only complete these instructions if you want to use a *ist DL camera.
** These instructions involve modifying system level files using a HEX editor. If you are not comfortable with this, do NOT attempt to do this or you could kill your system. Remember, BACKUP BACKUP BACKUP. These steps worked great for me but follow at your own risk!! **
Ok, lets begin...
1) Download this great patch by macintosh_tech
http://idisk.mac.com/macintosh_tech-Public
This patch contains an updated raw.plist file which includes the RAW information for the *ist DL. This patch also contains an updated libRaw.dylib file and an updated Raw Presets file for Aperture.
** Do NOT copy the libRaw.dylib file from this patch to the folder listed in the patch Read_Me. This file did not work on my Intel-based Mac and crashed my system!!
I was able to modify my original libRaw.dylib file using a HEX editor to get it to work on my system. Instructions for this modification will follow.
2) Open the .dmg of the patch in a Finder window
3) Open a new finder window and browse to /System/Library/Frameworks/ApplicationServices.framework/Frameworks/ImageIO.fra mework/Resources
*4) Backup the libRaw.dylib and Raw.plist files. Copy them to a safe location. For extra safety, you can just copy the whole Resources folder to a safe location (Make sure that you COPY it and dont MOVE it)*
5) Right-click the libRaw.dylib file and select "Get Info". Look at the bottom of the info window and expand the "Ownership & Permissions" tab. In this section, expand the "Details" tab. If the lock icon is in the locked position, click it to unlock it. Change "Owner" to your user name. If requested, enter your system password at this point. Close the info window. This step lets you modify the libRaw.dylib file.
6) Complete step 5 for the Raw.plist file.
7) Copy the Raw.plist file from the "Place In System Folder" folder from the patch to the Resources folder. It will ask you if you wnt to overwrite the existing file. Click "Replace".
8) Open a new finder window and browse to the /Users/YOURUSERNAME/Library/Application Support/Aperture/ folder.
* 9) Backup the "Raw Decode Presets.plist" file *
10) Copy the "Raw Decode Presets.plist" file from the "Place In Home Directory" folder from the patch to the /Users/YOURUSERNAME/Library/Application Support/Aperture/ folder. Click "replace" if it asks you.
11) Here's the tricky part. Download a HEX editor if you don't have one. I used 0xED. It is free and can be downloaded from
http://www.versiontracker.com/dyn/moreinfo/macosx/29521
12) Open the libRaw.dylib file from the Resources folder in your HEX editor.
Note: This is your original libRaw.dylib file from your /System/Library/...../Resources/ folder, NOT the file from the patch.
Use the Find function and search for the string "Pentax *ist DS". Make sure you are using "Search Type: Text" (or equivilent in your editor) and that you use proper case. When you find this string, change the "S" in the "DS" to an "L". The string should now look like "Pentax *ist DL". Use the "Find Next" function to find the next instance of "Pentax *ist DS". Again, change the "S" to an "L". There should be two total instances that you need to change. Save the file and exit the editor.
13) Open Disk Utility and repair permissions. This will set the raw.plist and libRaw.dylib files back to their original permissions.
14) Reboot the system.
15) You should now be able to view .PEF files natively in Aperture and iPhoto. I appologize in advance for any typos. Let me know how this works, as this is my first tutorial of this nature.
Macbook 2.0 Mac OS X (10.4.6)

It would appear that my last post was a moot point as the 10.4.7 update adds support for the *ist DL. It's nice to have it biult into the operating system now.

RAW DNG sequence / Edit Original with ACR within Premier

I need to speak to a Adobe Premier expert. I have a RAW DNG sequence shot on my Canon 5d Mark 3 via Magic Lantern imported into my premier project now. I want to edit the DNG's image settings with ACR (adobe camera raw). So i right click on my DNG sequence / clip and go to Edit - Original . ACR pops up and i make my image modifications. I click ok but the DNG sequence doesnt change, its stays the same.
Now i can do all this without trouble within After Effects, but it just adds another step to my workflow. When it should be working within Premier. Im still waiting to see if ACR will ever work directly within Premier.

Maybe whoever answers your question can give me some insight. I imported my DNG sequences to After Effects, because Premier wouldn't import the DNG sequences, and created a new comp for each of the shots I have. Later in Premier I imported all those AE comps. Now where would be the correct place to color correct and grade this? Straight in Premier? Or will I be loosing the flexibility of the DNGs? Should I do it instead in the AE comps? Or maybe it doesn't matter? Thanks for the help!

In case my input RAW/DNG files are already applied white balance , is there a way to cancel the white balance in light room ?

Hello I am new to lightroom and I am verifying this tool as a tool for raw converter (for image quality team)
In case my input RAW/DNG files are already applied white balance gain
Is there a way to cancel the white balance in light room ?
Thanks
Ron

Make sure that Develop Settings being applied during import is set to "None".

Prerendert mp4 replace with RAW DNG in After Effects

Hello,
I try to replace a mp4 clip with RAW DNG. The mp4 clip was made from the RAW DNG, but when I try to replace it, the length of the clip never fits.
Details:
1. RAW DNG recorded with 30fps
2. RAW DNG with Media Encoder to 30 fps mp4 rendered
3. mp4 import to AE
4. Replace mp4 with RAW DNG
Result:
mp4 clip length = 08:19:12
DNG RAW length = 06:39:04
The info window shows bith clips with 30fps .
Both clips shows: 0000000-0011973 (frame count from dng raw )
All Settings on 30fps:
Media Encoder: "Media / Indeterminate Media Timebase: 30fps"
After Effetcs: "Import / Sequence Footage 30 fps"
Premiere. " Media / Indeterminate Media Timebase: 30fps" (just in case - maybe encoder reference pp..i dont think so..but..)
What can I do? Im doing something wrong, or is it a software error?
Even if I dont replace, just import the raw dng to AE it show the shorter lenght, but as well 30fps in the info window.

I did a testfile.
I exported a clip (30fps) to png sequence (60fps) and add it to the media encoder and when I press the button "match source" Media Encoder shows me (again) 23,976fps, but when I manually put it on 30fps it really export with 30fps. So I have a mp4 with 30fps
So I import that mp4 to AE its 03:29, when I import the pngs itself directly to AE its 03:29. So my setting seems to be correct. I choose the same settings importing RAW DNG.
I recognize that Media Encoder doesn`t recognize that the RAW DNG is a picture sequence, in the import window the "import sequenze square" is grey out, but it imports it as a the picture sequence, but not with the correct fps.
Its confusing, because it shows in the the clip info, after rendering the correct fps (30fps), but its not 30fps , its more like 23,976 frames. So it really looks that its a adobe software error.
Is it?

Trouble converting RAW files with Camera RAW/DNG - CS4 Mac

Hello!
I am using CS4, with Camera RAW 5.7 and Adobe DNG 5.7. These are the versions listed as compatible with CS4. I am using a new Canon Powershot S100. Can I use newer versions of the RAW/DNG with CS4, or am I just out of luck? Please help!

Same story we hear again and again.
New camera, old software, and the often un-stated expectation that the software company should go out of its way to provide new camera support for free. First thought by those in the know is "you bought a new camera, why do you feel you don't need to buy new software to go with it?"
Those same folks who bought a new camera might never consider asking a camera manufacturer to make their new camera compatible with their old software. It's a funny disparity.
Adobe walks a tightrope of expectations. As it turns out, when you download the latest free DNG converter version they actually DO provide new camera support for free - it's just that converting to an intermediate file format is not quite as integrated or convenient as using the latest version of Photoshop with native support for that camera to just open the files directly. Nor do you get the SIGNIFICANT improvements in image quality that the newer converters provide.
Use the DNG converter, but if you care about your image quality you'll consider upgrading Photoshop. They really have made strides in raw conversion.

Prerendert mp4 mit passenden RAW DNG erstetzen

Hallo,
ich habe eine mp4 Datei, die ich mit DNG Raw ersetzen will. Die mp4 Datei habe ich zuvor aus den RAW DNG mit Hilfe des Media Encoders erstellt. Leider stimmt aber die Zeit bzw, Länge des Clips nie!
Details:
1. RAW DNG aufgenommen mit 30fps
2. RAW DNG mit dem Media Encoder und 30 fps zu mp4 codiert
3. mp4 in AE importiert
4. Ersetzen mp4 with dng raw
Ergebnis:
mp4 Datei Länge = 08:19:12
DNG RAW Länge = 06:39:04
Dabei werden im Info Fenster bei beiden Clips 30fps angezeigt
Beide Dateien zeigen : 0000000-0011973 (frame anzahl) an.
Soweit ich nachvollziehen kann stehen alle Settings auf 30fps:
Media Encoder: "Media / Indeterminate Media Timebase: 30fps"
After Effetcs: "Import / Sequence Footage 30 fps"
Premiere. " Media / Indeterminate Media Timebase: 30fps" (zur Sicherheit auch da)
Was kann ich da noch machen?

Antwort: Nachdem die DNG RAW Datei Sequenze in AME importiert wurde, auf den File-Namen , rechts klick, und "interpret footage" und dort die gewünschte Frame Rate einstellen...

Having trouble placing RAW / dng files in idesign 5.5. Any suggestions?

Having trouble placing RAW / dng files in idesign 5.5. Any suggestions?
Here's what i've done so far:
Updated my raw plug in
I shoot on canon rebel t3-i

Open the RAW or DNG file in Photoshop as a Smart Object. Then save as a PSD file. Place the PSD in InDesign with File > Place
InDesign cannot place RAW files. However, if you use the workflow I suggest, you can still edit the RAW/DNG files if needed. To edit, choose Edit Original from the InDesign Links panel, and the PSD image will open up. Then double-click the smart object and it will open in Adobe Camera Raw. Saving the changes in PSD will update them in InDesign.

Ordering Prints from LR Raw/DNG

I've got a boatload of raw/dng photos I need to print. What's a good workflow for ordering prints from an online service?
Say something like Shutterfly? Looks like there's a plugin for LR. I'd like to avoid mass converting to Jpeg/srgb... is there any service that takes a raw/proPhoto rgb? Or is that overkill?

JPG highest quality, full resolution with sRGB should be good enough for a place like Shutterfly, unless they gprovide formats for special paper, then you can convert to those, but be sure you specify they have a custom profile and no auto-adjustments are to be performed, otherwise things won’t look right since they’re likely to assume sRGB for the profile.
Raw cannot have ProPhotoRGB associated with it since it is raw sensor data not RGB data. And a raw file would be interpreted by the printing company using whatever software and settings they wanted, completely ignoring whatever you’d done in Lightroom.
What gives you the idea that you need to send raw photos, or even ProPhotoRGB photos? Is the prints going to be in glowing or fluorescent ink. I can’t imagine any other reason to use ProPhotoRGB as an image profile desitined for printed output since paper usually has a lower gamut than your monitor, even. You use ProPhotoRGB with 16-bit TIFs for intermedia or archival perposes. You wouldn’t want to use ProPhotoRGB with an 8-bit format or as a final output format for printed or display purposes since the gamut of the paper or display would be much smaller than ProPhotoRGB. Normally you use ProPhotoRGB as an intermediate format for images that will be adjusted further.

Linear Raw dng set color order?

Hi,
Is it possible to set the color order in a Linear Raw dng? I have B,G,R and not R,G,B. Is it possible to set this in the dng sdk as a tag? Or do I have to reorder my pixels?
Thanks a lot,
Greetings,

It actually does not matter what order the colors are in, as long as the color matrix tags use the same order.
(The colors don't need to be "red", "green", or "blue" either. They can be any three or four arbitrary colors in any order).

I cannot get .arw or jpeg files from my Sony A6000 to be taken into my Lightroom 4.4 via the normal "synchronise" process. I have updated my Pc to Adobe RAW/DNG 8.4 with no improvement. Can you help please?

With regards to your .arw files:
You need to either purchase and install Lightroom 5.4 -- OR -- download and install and use the FREE Adobe DNG Converter version 8.4, did you actually launch and use the DNG Converter?
There should be no problem importing JPG files into Lightroom from your camera, what happens when you try? Is there an error message?

Support for Pentax K-5 RAW PEF wanted

Request to add support for Pentax RAW PEFs for newly released Pentax K-5. Needed much.

To send your request to Apple you really should used the "Provide Aperture Feedback" in the pulldown menu under Aperture.
This is a user to user forum where you are talking to other users like yourself and not Apple.

Pentax *ist DL2 RAW Support

Hi,
I really really want to use Aperture, but Mac OS lacks support for my camera's RAW format. I have a Pentax *ist DL2, not a particularly new model, but the only DSLR I have, and thanks to my collection of Pentax lenses, im unlikely to change anytime soon.
I have done some experiments with changing the RAW.plist file (as described on the ok! pentax! one thousand! blog) which works, but only if I convert my .PEF (Pentax RAW) files to DNGs first. In Leopard, the RAW.plist file no longer exists, so I had to try another approach - modifying the RAW files themselves and changing the identifier string from *ist DL2 to *ist DL.
Since the DL and DL2 appear to use the same RAW format, it should be trivial. However, I can no longer justify the hassle of hexediting my RAW files just to get the program to see them.
I know Joe Schorr said the team are ACTUELY aware of the need for supporting the newest cameras, but PLEASE PLEASE PLEASE can we have support for my lowly old DL2???
Cheers

http://www.ok1000pentax.com/2006/06/waiting-for-aperture-and-iphoto.html
Thats the blog entry I was on about. Seems the raw.plist does exist, but I dont want to have to convert to DNG.
Please Joe Schorr, if you could help out us DL2 (and DS2) owners, we'd be very grateful
