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.

MacBook 5,1 unibody, Mac OS X (10.6.4), My first mac, happy about it.

You can't convert a raw master into a different type of master Aperture doesn't work that way. What you will have to do is export the image in the format you want, import that new image, then delete the original master.


Note that any metadata associated with the original will be lost. To Aperture the new master will be a totally different unrelated image to the original.


And while I'm sure you have good reasons for wanting to do this I'd recommend that you give it some thought before deleting your original files.

you seem to know your stuff Frank!


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?


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...


as i wrote in my first question, is there an easy way to adjust the values of a 100 raw files automatically? i tried auto enhance but it makes the images look "fake".

what do you recommend for just adjusting exposure, colors (without skin reddening) and a little noise reduction with a natural realistic look as the end result? i would like to just do this really easy and automatically for about a 100 raw files in one batch (just some social pics that don't matter much).


a reply is greatly appreciated and anticipated 🙂

best regards, Joakim.

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

Hi Joakim. To put it baldly, you seem to be missing the point of Aperture, which is to as efficiently as possible create a flexible lossless workflow for converting, developing (some say "processing"), preparing for publication, and publishing RAW digital photographs.


JPEG was developed for the Web, and does a great job compressing images for transmission on the Web and display on computer screens. Compared to RAW, it has (in the words of an engineer) "fairly limited editing headroom". Many photographers, for many reasons, want little or no limit on the "editing headroom" of their captures. Aperture excels at this.


One of the ways it does this is that it does not store any full-size image-format files. Almost all of the images your work on in Aperture are created on-the-fly from text instructions applied to your Master file. When you need an image-format file of one of the images in your Aperture Library, you must export it. "Export" to Aperture, means "create an image-format file".


To take advantage of what Aperture does, you should import as big and uncompressed image files as your can -- and keep them that way. Aperture performs no compression at all on your these files. Once they are imported into an Aperture Library they are referred to as "Masters". Every image in your Library has a Master.


Compressing your Masters in any way that loses information (JPEG is designed to throw out information, retaining just enough -- and no more -- to make the image look good on a computer screen) violates the core design goal of Aperture.


For many, this is not a problem. They purchase storage (and back-up storage) as needed. Aperture makes it very easy to store your Masters on any drive attached to your computer.


You should read up on "Referenced Masters". There is a good section in the User Manual, and there are good posts on this topic almost every day here in the Discussion.


Your other questions -- about editing and batch operations -- are best addressed in separate threads.


HTH. :-)
