Extend Your Range

Ordering Close Focus • Sign Here • JPEG Vs. JPEG • The Coolscan Dustup

Labels: How-ToColumnTech Tips
I'm not certain what this means for me as a photographer, other than that I want my hour of testing back. There are specific reasons to shoot in RAW and in JPEG formats. RAW files have much more data and thus can be manually processed to produce the best possible end results in terms of resolution, contrast and color. If you're looking for high quality and large prints, you need to start there. Camera-captured and
-processed JPEG files are useful for photographers who don't want to do a lot of post-capture processing, possibly make small prints or share electronically. Additionally, I use camera-captured JPEGs when creating a huge Gigapan panorama and time-lapse sequences. I capture in both formats simultaneously when I'm in the field so I can quickly review the smaller files on my iPad.

But one thing we know for sure: There's no advantage to shooting in RAW and then converting the unprocessed file to a JPEG. If you need the JPEG, either capture it in the camera, or better yet, manually process the RAW file to its maximum quality and convert the finished file to JPEG format.

The Coolscan Dustup

Q I'm attempting to scan my library of Velvia 50 slides to high-resolution TIFF scans using a Nikon Coolscan 5000 scanner with ICE [an automated dust-removal function] on. However, I recently read in OP that you recommended having the ICE function turned off. Do you have any suggestions on what will help me get higher-quality scans and eliminate the dust?

A ICE has never worked well on Kodachrome films. If you can still use the last version of the Coolscan software with your computer's operating system, the ICE dust removal is good for Fujichrome Velvia and all Ektachromes. But since Nikon has stopped making and supporting the work-horse Coolscan scanners, the software no longer works with recent operating system upgrades and hasn't functioned at all with the last two generations of Mac OS. My solution has been provided by SilverFast 8 software (www.silverfast.com), which has an excellent dust-removal component and works with the latest operating systems on all types of films, including Kodachrome, on Coolscans and a variety of other film scanners.
