Avoid unintentional motion blur:

Assuming an accurately focused subject, you can maximize image quality by eliminating

unwanted motion blur. To reduce the effects of camera shake, use a tripod when possible.

Use an Image Stabilizer lens for handheld photography. To eliminate unwanted blur

caused by subject movement, use faster shutter speeds or electronic flash.

Avoid inadvertent camera or subject movement after focus lock:

If you are using One-Shot AF, do not move the camera towards or away from the subject

after locking focus, especially for subjects within 15 feet of the camera.

Avoid the use of small apertures with wide-angle or wide zoom lenses:

Small apertures can cause sharpness-degrading diffraction when using wide-angle or

wide zoom lenses.

Image Quality

Consider the use of in-camera sharpening:

Optimization Tips

If you shoot JPEGs and you wish to reduce or eliminate the need for post-processing in

order to speed up your workflow, you may find that increasing the level of in-camera

sharpening is effective.

Apply post-process sharpening effectively:

Canon EOS digital cameras have an anti-aliasing filter installed on the image sensor.

This filter improves color rendition and practically eliminates moiré. The liability is a

slight reduction of sharpness. To reduce the softening effect of the anti-aliasing filter we

recommend applying an unsharp mask to the image in Adobe

Photoshop

. Although

there is no such thing as a "best" setting for all applications, we suggest the following

as a starting point:

Amount: 300%

Radius: 0.3 pixels

Threshold: 0 pixels

Understand that image magnification affects perceived sharpness:

When viewing images at 100% magnification, the actual image size can be as large as

4 x 6 FEET depending on the resolution of the camera. If your images are regularly

printed at 8.5" x 11" or less, the equivalent magnification with EOS-1D Mark II would be

approximately 33%, or 25% with an EOS-1Ds. Try printing your images to evaluate

sharpness.
