How to activate auto focus (AF), when using 1.4x or 2.0x
teleconverters with f/5.6 or slower lenses.
is simple. Just place a small transparent piece of tape
on the last 3 pins of the
converter. The tape should be placed on the left hand
side of the converter when looking at it from the lens
connection side. With these three left pins covered, the
converter continues to operate on the D30 with the AF
activated. It works great with the Canon
100-400mm f/4.5-5.6L IS.

How to use the 550EX to aid with Infrared light ONLY:
Press the LCD lighting button; hold it down for 3 seconds.
The CF symbol along with "F1 0" will come up
on the LCD screen.
Click on SEL/SET once. The "F1 0" function will
Click on SEL/SET two more times until you see "F3
While the function "F3 0" is blinking, click
on the "+" button changing it to "F3 1"
Click on SEL/SET one more time and then the "mode"
is it! Now the 550EX is set to "TTL" mode. It
provides infrared light, which aids in focusing in low
light conditions, without triggering the pre-flash or
return to E-TTL mode, follow the same procedure (as above),
except for one adjustment. You should change the CF function
back to "F3 0" (using the "-" button).
How to increase the D30 RAW dynamic range, simulating
a "gradual filter" when shooting landscapes:
are several techniques that I have developed to aid in
capturing a high contrast scene with extended dynamic
range. I recently wrote an
article revealing a systematic approach to this very
in mind that the "gradual filter" technique
only works with images that have a linear contrast range.
On the other hand, the DRI
Photoshop action is capable of combining two images with
different exposure settings into a much larger dynamic

action, which recovers a fair amount of detail in over-exposed
How to sharpen D30 images:
D30 images are well known for outputting somewhat "soft"
images. In my opinion, Canon's approach to sharpening,
offers users great versatility when editing D30 images
by aiming for high quality results.
D30 sharpening algorithms are designed to provide a low
setting of sharpening even when using the high sharpening
parameter. This is preferable, since you can sharpen your
own images to your taste and avoid several side effects
that can be caused by sloppy sharpening settings.
have developed a Photoshop action, which automatically
sharpens only the subject. You can choose and customize
what you specifically want sharpened and to what extent.
This provides natural looking sharp images, free of halos,
noise and artifacts. You may download the free EdgeSharpen
8-bit from my "free Photoshop
(EdgeSharpen 8-bit has only an AUTO setting and it's not
compatible with 16-bit files).
also developed EdgeSharpenPRO
16-bit, which has several automatic options as well
as medium and advanced controls. This action works with
8 and 16-bit images.
When to use the non-linear and linear ICC profiles:
do not recall a rule of thumb on this matter. It is a
question of preference or level of software knowledge.
Here is my opinion.
linear profile is for those
who want to obtain the pure RAW image, with no parameters
adjustment to it except from the white balance.
Linear images will appear softer (no sharpening applied),
flat (no contrast applied) and pale (no color saturation
applied). However, it still provides the perfect image
for post editing. Curves will appear smoother and less
jagged. Images look sharper when sharpened in Photoshop.
They are also cleaner, and have less noise, since no sharpening
is applied to them.(Especially high ISO pictures).
addition, the dynamic range is greater and color gamut
is larger in linear images. It is not intended to be used
for snapshots or for those that don't feel comfortable
editing images in Photoshop. It is a dream for those that
want total control in post processing.
the other hand, the non-linear profile
provides accurate, natural looking colors. It can only
be used with non-linear converted Tiffs or jpegs. However,
keep in mind that there may be more noise, jagged curves,
and smaller color gamut in non-linear images.
How to use D30 Auto WB with great accuracy
Several D30 users have reported getting blue casted images
when setting their white balance to AUTO. To me, the discrepancy
affects not only the blue, but the red channel as well.
I developed D30_AWB_fix,
which will instantly fix all your Auto White balanced
shots for greater accuracy. You also have the option of
batching all the images inside a folder using Photoshop's
For those using the linear and non-linear ICC profile
actions with Auto WB images, first run the
D30_AWB_fix_v1.1_.atn action prior to playing the
