No more RAW + JPG?

Go to last post
Definitely very nice utility, thanks for pointing it.

However I'll add that at least K10D stores not the best quality jpegs in RAW files. Considering that K20D jpegs are nearly 10MB in size, I doubt that K20D stores full size best quality jpegs either.

Also it isn't the only utility that do that.

pef2jpeg exists a couple of years already

Also if you want to quickly review RAW files, many advanced picture viewers (like IrfanView, FastStone, xnView) are able to load stored jpeg instead of rendering image from RAW data.

I've used various (Windows) utilities that do this over the years.
With Pentax files I generally use PEF2JPEG which is chap and cheerful
(ie free) and has been around as long as the PEF format has existed

I like that one, it takes no space so you can put it on every SD card just in case.

There is also the Pentax Photo Browser, right-click on a PEF and select "Extract JPEG", that will do the same.

There's also dcraw (with the -e option), and probably a host of others. Still, I can see where having it as a GUI context menu option could be handy for some people; a clever idea, that.

Indeed. And in Windows it's trivial to add a new action to run it from the context menu you get when you right-click on the raw file if you want GUI "integration" without actually meddling with Explorer at all.

I don't like installed third-party shell extensions like the one here, they can (and often do) slow down Explorer and can affect its stability. I'm not accusing this one of being badly behaved (but it could be), I just prefer other ways to achieve a similar result which are are both cleaner and bullet-proof.

So with these utilities, what jpeg settings are applied to the extracted jpeg? Since there is no jpeg created in camera are the camera settings ignored or are they still applied, i.e. sharpness, saturation, hue, etc.

The JPEG is created in the camera, but it is stored inside the PEF rather than written to a separate JPG file. Imagine it a bit like storing a JPEG in a ZIP - not quite the same but similar in concept, saving one file inside another "container" file.

The utility just reads it from the PEF and writes it to a separate file; it does no image processing at all.

The camera settings.

There are several JPEGs created in-camera. They are embedded into the RAW file, in the "header" so to say. (Not technically correct, but you get the #umm# picture). Most cameras use these embedded JPEGs to render the preview/review screen and even the histogram.

They are applied. The "only" drawback is that the JPEGs are of the one-star * quality. But that's still plenty to print 13cm x 18cm ( 5" x 7") or create contact strips or proofs.

Because of pef2jpeg, I never understood the want for shooting RAW&JPEG.

from what i have read, if your dslr is a 6mp size, and 3000x2000pixels. and you take a raw shot that raw image to be is 3000x2000 pixels, BUT the embedded jpeg, you did not take a raw+jpeg, is NOT going to to be a 3000x2000pixels jpeg. it is going to be a much smaller size. so you cannot take the jpegs from this program and use them for all your prints, no matter the size, you simply do not have the resolution.

the only way to get the full resolutiuon jpeg is to take the raw+jpeg(if the jpeg is full sized, and not just basic or small) or the pure jpeg only.

No, the embedded JPEG is full resolution. There may be other, smaller additional JPEGs but in the case of the PEF format one is always full resolution.

The JPEG quality is only one star (the smallest file size possible) but the resolution is not affected.

No, that's not the case.

This is incorrect.
Check with pef2jpeg.exe
I've used it for hundreds or thousands of my DS pictures.
There really is a full size JPEG in that RAW file.

Hey John,

could you maybe once in a while be slow?!
I'm starting to look like an idiot here. Yes. I said "starting".
...
Who's laughing there?

okay on the resolution. BUT the embedded jpeg is the lowest quality, as you say 1 star. so it cannot be used to make a good 8x10 or larger print. the jpeg thus gotten is of limited use.

also, it is for pentax PEF raw files only, cannot be used for any other raw files.

then, still the the only ways to get a full resolution full quality jpeg is to have the camera take a raw+jpeg(at full jpeg qualtiy and full resolution), or take a full resolution full quality pure jpeg, which the k20 can do.

Yup.

I would take a wild guess that only very few people will recognise the difference between a and * JPEG printed at 8x10, even if you are talking in inches ;)

Seriously, if I want to print 8"x10", I certainly want to make use of the RAW benefit. If someone doesn't want that, then, by all means, I am sure a * JPEG will suffice, too.

Basically everything in this world is of limited use. However, it is very good for quick slideshows, contact sheets and even printing, all without filling up your memory card with extra data.

Correct. Being in the Pentax forum, I might be interesting for one or two, though.

The appeal of shooting RAW+JPEG still escapes me, but to each his/her own.
