Hi all, Which would be the best option for upsizing camera raw settings or left until opened in photoshop.

Hi Liam, if I was upsizing I would definitely do it in Camera Raw, instinct and logic tell me that would be the best way. I expect there are others who would leave it until later in the workflow

Liam,
I shoot digital with FUJI S5 and S2 DSLR's and I've done extensive testing on the best way to upsize the 4256 X RAW files
I get from them. I'm currently using Photoshop CS4 and Adobe Camera Raw (ACR 5.4) I get the best results by upsizing
the RAW file in ACR at the time of conversion from RAW to 16bit TIFF files. The funny part about this is that I also have a
Canon G9 and it was a Canon Tech Rep that suggested that this would give me the best files from the G9. I've tried other
3rd party software and have found that ACR gives me the best files at 5120 X at 300dpi. Then it is a simple matter to do
minor tweaks and a bit of spotting before dropping them to 8bit JPEG's for upload to Alamy or other agents or libraries.
I've tried the same process with CS2 and CS3 and was not as pleased with the results. I also quit using Nikon DSLR's
after the D100 so I have not tested the current Nikon bodies using the current Nikon software.

This is only partially a question about the difference in methods, it also is about future-proofing a workflow.
It depends where you are going to send the images, more especially long term. If Alamy is only going to ever be your only library then it makes sense to upsize in ACR. However if you want, at some time, to send the TIFFs to a collection that wants native file size you will have to rework the RAWs.
I never use a RAW processor to upsize so that I always have the benefit of long term access to a native file size TIFF.
ACR will give the best results for upsizing....although if you use a camera which produces large files (mine produces 47.5mb 8bit native) the difference in upressing the TIFF is insignificant.

Many thanks for the info, I do hope Chucks testing was not all that bad as it might mean me having to purchase new equipment as I use the Nikon D200
& CS2.

Geoff,
You make a very good point. I often do other edits from shoots for agencies outside of Alamy. I have yet to need to go back to my original
RAW file and make another TIFF conversion to the native size (In my case it would be 4256 X), but I can see that being requested. I do save
all RAW files with the IPTC information.
Keep in mind that "I" shoot what would be called "Editorial" so I do not change or modify an image beyond what would be considered appropriate
in the editorial market.
P.S. Liam, As I said I have not touched a Nikon DSLR since the D100. I am a big fan of CCD sensors and I believe the D200 is a CCD sensor not
CMOS. I was not a fan of CS2, but ACR in CS4 is a huge improvement, My opinion. The upgrade from CS2 to CS4 can be had pretty cheaply, if your
computer will support it? Speaking of "Support" I had an awful time with Adobe's tech-support during the last year.
Chuck (Yall know)
