RAW question

I would have posted this to the Outsider forum but it says I don't have the proper rights to do so, sorry.

I just got some RAW files (.PEF) produced from a Pentax K2000.

Interestly, I CAN open, view, and do minor tweeks using the IrfanView. HOWEVER, when opening the same file in XPro5 or CorelPhoto Paint X4, the image initially displays for an instant and then goes whacko. See attached.

What could be the reason and how can I test? I am hoping its not my graphic card. Could it be a memory setting in XPro5?

I have a Dell Laptop, Latitude 830, with an NVidia Quadro NVS 140M, 32 bit at 1680 x 1050.

I can post a .PEF file to an FTP site is anyone would be interested in doing some testing.

All I will need is an email address. You can PM me if you wish.

Sure, send a copy to sledger [at] gmail.com John. I'll take a look.

I dunno John, I think you are on to something here.

Just print out about 20, sign and number each one, and sell them at the next art fair. :D

They'd probably sell well at the upcoming fair in Eugene, Oregon (hippy capital of the world ... think time-warp).:rolleyes:

Steve,

Be on the lookout for an email from Rapidshare. It will have a download link and delete option.

OK John, but you could have sent directly to my gmail address, file size isn't an issue, RS takes too long, first a 30 second wait and then they throttle the speed.

Yeh, but I'm at work and we've got a file limitation on attachments. :)

John the exact same thing happens for me in X5.

IrfanView opens the embedded .jpg, not the RAW - which is why it is so fast when doing so.

Lightroom 1.4 can't open it either, likely an unsupported update to the K2000 firmware (LR 1.4 doesn't support my G10 RAW either)

I suggest you open in IrfanView, copy to clipboard and paste into Xtreme 5 (though I bet you already did that ;))

Xtreme cannot properly handle/develop any RAW, it simply doesn't have the tools. As I've mentioned before somewhere, Xtreme's RAW support is just an 'enabler'..

Thanks for investigating.
John

FYI.

I did a bit of experimenting and converted .PEF to .DNG via Pentax Photo Browser 3.

Even though it is not shown in Xara5's dropdown list of the Import Dialog, the import filter will recognize DNG (Adobe's Digital Negative non-proprietary format for storing RAW data).

In the import dialog, choose "All Files" from the dropdown list.

It is there John,

It's one of the supported RAW formats.

I too use the DNG converter for my Canon G10 RAW on order to open them in Lightroom 1.4

Some camera manufactures are adopting the DNG format (Casio, PENTAX, Samsung, Leica, Hasselblad, and others)
I'm actually very interested in the new PENTAX K-7 (also writes to DNG)

God, without studying hard and close, my eyes just don't pick things anymore when things are bunched together. (I need some sort of a quick-auto-focus thingy in my eyeballs).

Sorry about the erroneous info in my previous posting.

I read somewhere that DNG to RAW will be analgous to Adobe's pushing of PDF as a standard for document handling.

I believe this is the plan ;)
