Thank you for your purchase of the Canon Camera.
This README file contains the latest information on the Canon Camera TWAIN
driver. Please read this file before using the TWAIN driver.
Cautions Relating to the TWAIN Specification
The TWAIN specification is periodically updated and software development
companies modify their software to reflect these changes. Accordingly, problems
may occur because some applications do not fully comply with the current TWAIN
specification. Canon works closely with a range of software companies to
identify and resolve these problems so that our users can enjoy trouble-free
use of the software.

1. GENERAL ISSUES
===================
(1) Disk Space
The TWAIN driver creates a number of temporary files.
These files will be deleted when the TWAIN driver shuts down. However, they
may remain on the hard disk if the TWAIN driver crashes for any reason.
The next time the TWAIN driver is activated, such temporary files should be
deleted, if any.
(2) 16-bit TWAIN and 32-bit TWAIN
The Canon Camera TWAIN driver is a full 32-bit application.
If you see the "TWAIN_32" and "TWAIN" options on the menu in the application
rogram, always select "TWAIN_32".
2. Defects occuring on the part display card
============================================
When the Twain driver is started from PhotoShopLE5.0 on the part display card,
the work may become unstable.
If this occurs, after carrying out the dispinit.exe programme, start up
PhotoShop and then use the Twain driver.
When you start up the system, we recommend that you register dispinit.exe in
the Windows start up programme.
dispinit.exe is in the same folder as installer (setup.exe).
On CD, there are [SOFTWARE / TW_USB / Camera type / Language] folders.
3. Cautions relating to Specific Applications and System Configurations
=======================================================================
Canon has tested the operation of the driver on as many TWAIN-compatible
applications and system configurations as possible. The following compatibility
problems have been found.
(1) Transferring images to Photoshop 5.0LE
The maximum number of images that can be transferred to Photoshop 5.0LE at
one time is 30.
(2) Cautions relating to communication between the Canon Camera TWAIN driver
and a Canon digital camera
When the TWAIN driver is running and is connected to a camera, the driver
makes communications with the camera periodically. Do not operate the camera's
power switch, remove the memory card or battery, disconnect the communication cable,
or otherwise interfere with the communications.
Such actions may cause misoperation on some PCs.
Wait until the TWAIN driver has shut down before doing such actions.
(3) Cautions relating to USB and IEEE1394 connections
Do not place your computer in standby mode while a Canon camera is connected
to the USB or IEEE1394 port.
If the computer goes into standby mode while the camera is connected to the USB
or IEEE1394 port, do not disconnect the cable from the computer. Instead,
restore the computer to normal operation mode with the cable still connected.
Unplugging the cable with the computer in standby mode may cause some computers
to not recover correctly from standby mode. For details on standby mode,
refer to your computer's manual.
4. Cautions relating to Windows98SE
====================================
Users running the Windows 98SE operating system are recommended to install
the following update program from Microsoft web page to ensure more stable
operation.
"Windows 98 Second Edition 1394 Storage Supplement"
5. Cautions relating to Windows98SE and WindowsME
==================================================
When the camera is connected to the computer please set the auto power off
function to [OFF].
6. Cautions when connecting to a Camera
========================================
Communications with a camera cannot be performed while its LCD monitor is on.
If the LCD monitor is on, turn off it (by semi-depressing the shutter button,
for example) before connecting the camera to the computer.
7. Cautions relating to Imaging application of Windows 2000
===========================================================
Please select "8 bits per color channel" on the Preferences Dialog
when Twain driver is launched from Imaging application of Windows 2000.
The Imaging application cannot receive 16 bits per color images,
so if "16 bits per color images" is selected the transfer will not work properly.
8. Cautions relating to Short-cut key for image rotation
========================================================
The following short cut keys for image rotation do not work.
Ctrl+R
Ctrl+L
Please use the "Rotate right 90 degrees" and "Rotate left 90 degrees" buttons
on the main window tool-bar for image rotation.
9. Cautions relating to thumbnail update after changing
RAW image conversion conditions
============================================================
Please refrain from using mouse operations while updating multiple thumbnails
after changing RAW image conversion conditions.
Mouse operations when updating multiple thumbnails may cause
invalid display of thumbnails.
In such case, please change the size of Twain driver main window.
Then valid thumbnails will be displayed.
10. Cautions relating to TIFF(16bit/ch) format file.
====================================================
TIFF(16bit/ch) format files saved by Twain driver will not display correctly
on Windows Explorer.
11. Cautions relating to EOS-1D Camera
======================================
1) Image properties for bulb exposure
The correct time value is not recorded for the image's shutter speed property
in the case of long-duration bulb exposures of 100 minutes or more.
2) Personal function and Custom function setting
Notes on using the Personal Function settings "P.Fn-4: Set the maximum
and minimum shutter speeds" and "P.Fn-5: Set the maximum and minimum apertures"
If values such as 1/750 seconds or F4.5 that are not fixed increments are
specified as the maximum and minimum values, the actual control and available
setting range will be slightly different from the values set in P.Fn-4 and P.Fn-5.
When C.Fn-6-1 and C.Fn-6-2 are used in the "C.Fn-6: Exposure Level Increments"
Custom Function setting together with the above Personal Function settings
If values such as 1/3200 seconds or F6.3 that are not fixed increments are
specified as the maximum and minimum values in P.Fn-4 and P.Fn-5, the actual
control and available setting range will be slightly different from the values
set in P.Fn-4 and P.Fn-5.
3) 8-bit linear image transfer setting
Dark region noise may be noticeable if image adjustment is performed using
retouching software on an image transferred using 8-bit linear image transfer.
Use of 16-bit transfer is recommended for linear transfer.
4) IPTC information setting
IPTC information cannot be set at [All] image display format.
To set IPTC information, select [EOS-1D RAW] or [EOS-1D All] display format.
5) Selection from the [White Balance] list box after activating
[Click White Balance]
When you activate [Click white balance] on EOS-1D image, it has priority and
even if you select white balance from [White balance] list box,
it is not effective.
Disable [Click white balance] by clearing the [Click white balance] checkbox
to enable selection from [White balance] list box.
