1Ds and 24mm f/1.4L: Resized larger image


Are 1Ds files too large?

It depends on your photography background. Film photographers are accustomed to working with huge files and most likely will not be intimidated by the output size from an 11.1 MP digital camera. So, if you are used to scanning film, 1Ds files are not that large. However, for the rest of us digital shooters, four to six megapixel is the norm. Imagine my hesitation when I began to think about a workflow for this massive file size.

You may want to consider whether or not an output of an 11.4MB raw file will aggravate your system configuration and workflow. After converting your RAW images to 16-bit Tiff files and opening them in Photoshop, you will have a file that is approximately 70mb to work with. This should not present a problem if all you will do is sharpen it, convert to 8-bit and save. However, when correcting tone, color, and using several layers, this number adds up pretty fast. Scratch disk and RAM are crucial and that is what Photoshop is hungry for. Your system needs to have enough to work with or it could slow down considerably, especially when handling multiple layers and working with several files at the same time.

For testing purposes, I worked with 1Ds files using a Pentium IV 2Ghz with 2GB RAM and a 200mb of empty disk space for scratch files. I did not experience a dramatic slow down in image processing. This was probably due to the comfortable amount of ram and available disk space I had. If you your system configurations lack processor power, but you have plenty of RAM and available disk space, you could still easily work on the 1Ds files.

 


New software: File View Utility: Resized larger image

 

The 1Ds comes bundled with new software called, File Viewer Utility. It is standalone software with the ability to send your converted files directly to your editing software. It is user friendly, easy to install and basically converts your RAW files effortlessly. I found it rather similar to the software bundled with the 1D, even though it has a few enhancements.

 

 

How about RAW conversion times?

I compared RAW conversion times from the 1Ds and 1D. As expected, converting your 1Ds files will take approximately twice as much time regardless of your system configuration. Here are the results:

1Ds: RAW to 16-bit TIFF

  • Both false color and false resolution checked: 10 sec
  • Linear with false color and false resolution checked: 8 sec
  • Only false color checked: 8 sec
  • Both false color and false resolution unchecked: 6 sec

1D: RAW to 16-bit TIFF

  • False color checked: 6 sec
  • Linear with false color checked: 5 sec
  • False color unchecked: 3 sec

 

New to the 1Ds: False Resolution Filter

Chuck Westfall, is the Assistant Director/Technical Information Dept. of Camera Division/Canon U.S.A.
In an email he sent me about this new false resolution filter, he wrote:

"The false resolution filter setting is found in the Preferences tab for RAW file processing with the new File Viewer Utility software. It is a signal processing algorithm like the false color filter you should already be aware of from many previous Canon RAW file conversion software applications such as RAW Image Converter 2.0. In this context, "false resolution" has to do with a certain type of noise that may appear in high-frequency (i.e., finely detailed) portions of an image. The sample image shown to us by Canon Inc. compares detail in a woman's hairstyle with and without the filter applied. As in the case of the false color filter, there are certain kinds of photos where the false resolution filter algorithm can be omitted to reduce RAW file processing times."

After reading his email, I assumed that this filter would be useful for reducing artifacts in images that have a great amount of fine detail. So I ran some tests, and while editing, I did notice this to be true. But, the differences were so minute that they could only be seen at high magnifications and are were not even noticeable at 100% view.

 

 

The Canon standalone File Viewer Utility bundled software, offers everything you would ever need to tweak and browse your RAW files. The ability to modify your image before converting it to a tiff file is one of the joys of digital photography. Having the choice to alter exposure, color balance and color spaces while seeing the results is addictive.

 

Included Software

Two software discs are include with the EOS-1Ds. One contains Adobe Photoshop LE 5.0. The other is Canon's Solution Disk software for both PC and Mac which comes with PhotoStitch, File Viewer Utility, RemoteCapture, ZoomBrowser EX/PhotoRecord and the necessary drivers for your system. The new File Viewer Utility is currently not compatible with Mac OSX but is planned for release during the first quarter of 2003. All you need to do is attach your camera to the computer with the included IEEE-1394 "FireWire" interface cable, and you're ready to get started.

 

What is included in the box?

Included with the Canon EOS-1Ds digital camera are the following items:

  • Eyecup for optical viewfinder
  • NiMH NP-E3 battery pack with protective cover
  • NiMH battery charger
  • DC Coupler Kit
  • Neck Strap
  • Hand Strap
  • IEEE-1394 "FireWire" Interface Cable
  • EOS Digital Solution Disk software CD and Adobe Photoshop LE 5.0 CD.
  • Instruction Manual, Registration Information, and Quick Guide

An optional accessory Data Verification Kit (DVK-E1) is also available. It consists of a dedicated IC card and a card reader that that has the capability to verify whether or not original 1Ds files have been altered (Windows 2000/XP only).
