RAW FILE

I have a question and I need your help guys. I recently covered a small wedding (my very first paid wedding gig!) and I took all the shots in Raw. Now I have my 400D Canon Utility Software where I can view the RAW files and transfer it to Photoshop so I can edit and enhance them. Now, when I save it on a CD, it becomes TIFF instead of JPEG. My question is, can the pictures be printed locally even if they are in TIFF files? If not, how can I convert it to JPEG.?

Hi,

I feel the you can print in Tiff form too... But sometimes a local shop ask for JPEG format... Now to convert them to jpeg... idea is very simple.. while saving in the file in PS .. Click on "Save as" and in lower field chose "jpeg" as a file fromat.. That is it

Thank you sooo much for all your help. Terry, I do have the Canon software but it takes a while before it gets transfered to PS but thanks for the tip about batch save!

Yurick, I downloaded a plug-in from Adobe and it works just fine! It's a lot easier than the Canon DPP software, and yes I did change them to 8-bit mode :) Thanks a bunch!

Liu thank you for the info!

Thanks again guys!

If you use the Photoshop provided RAW engine, you can transfer it from RAW to JPG when you open the image. It is probably best to leave in TIFF format for all of your post processing and once you are complete, then do the Save As.. to jpg. If you don't finish the PP and need to go back, each time you save the jpg you get more data loss. As a tiff, you will not get a single pixel of data loss. The one and only save as to jpg will not result in any noticable data loss.

I use Photoshop CS3 & ACR to process my raw files. I prefer to print from the largest .tif files I create after editing the raw files for the best quality prints and then I will change to 8-bit and save a small jpeg image for posting on the web.

I attended a pro workshop where they printed out a 20x30 from a tiff, and then another from a jpeg saved once at the highest quality. We could find no difference in the print or pixel peeping. Then the guy opened the jpeg, made a slight adjustment (just added a dot with a brush), and saved the jpeg at quality 8 (out of 12). He did this a dozen times in a row, before using the file to make a 20"x30" print. We could find compression artifacts when pixel peeping, but with all 3 prints hanging side by side we could find no difference even with our noses press right up against them. The point of the exercise was to demonstrate that reasonable jpeg use poses no threat to image quality, and you'd have to be almost intentionally destructive, repeatedly saving at reduced quality, before it becomes an issue in the real world.

Ink jet printers may be able to take advantage of 16 bits. All C print machines that I'm aware of work in 8 bit sRGB, and there will be no quality difference between printing from a jpeg or tiff. I edit in raw or 16 bit tiff ProPhoto RGB, but I save my finished files for the lab as 8 bit, sRGB, jpegs (quality 12).

Recently I set up a SmugMug album for family pics. Because uploading took so long I tested saving the files at level 8 instead of 12 (it cuts the file size almost in half). I figured it was unlikely any of the family was going to order very large prints, and I didn't think it would effect quality much. Comparing 8"x12" prints made from quality 8 and 12 jpegs I cannot discern a difference.
