Why
would you choose the linear 16-bit mode?
RAW
files converted to Linear 16-bit mode have broader
dynamic range and color information (larger color
gamut). In addition, linear 16-bit files are free
of any sharpening algorithms and therefore
images will have even lower noise levels then non-linear
(normal) 16-bit images. The linear image provides
image data without any processing with the full sensor
dynamic range. The 16 bit’s file gives you 4096
points accuracy versus 255 in 8 bit images and therefore
more room for post-processing preserving original
dynamic range.
Previously, the linear 16-bit mode
could not batch several images, and it was a bit complicated
to use if you didin't feel comfortable editing images
in Photoshop. Now, it is a dream come true for those who
strive for the highest image quality and control in post
processing. With the new LPbatch, all users now have access
to the best image output the Canon EOS D30 can provide.
A
very high quality custom linear ICC profile is included
with this action for ultimate image accuracy. The
combination of linear file + Custom ICC profile eliminates
banding completely and provides accurate colors + cleaner
files for your professional needs. In addition the most
sophisticated custom made sharpening technique is built-in
and available for every saturation option.

This action works with
the Auto white balance and RAW mode. However, for better
results I recommend using Custom white balance sampled
from a Kodak gray card. With LPbatch as your post-editing
tool, all you need to do before you shoot is concentrate
on composition. Leave your post-editing work aside and
let the action complete it for you with its smart algorithms.
Another added feature is that LPbatch
can be used efficiently with Photoshop's batch mode. Just
choose your desired parameter and let Photoshop run though
hundreds of images at once! (Default options only take
4 seconds/image*)
D30 LPbatch is
compatible with Photoshop 6.0 or higher (PC and MAC) -
All Photoshop languages (Japanese, German etc.).Not compatible
with Photoshop LE or Elements
I
have noticed a few discussions on the net about the "softness"
of D30 images. Some people have even mentioned negative
feelings about using the Auto white balance. In my opinion,
the D30 is capable of delivering top image quality. However,
the camera's highest image quality is sometimes masked
by the 16-bit linear mode.
Canon provided us with the tools on how to convert our
D30 RAW files into 16-bit linear
mode files, but forgot to tell us what to do
with them afterwards. The result is a dark, unusable image,
that is difficult to profile. Now the LPbatch
Photoshop action comes to the rescue!
With these actions, the linear mode offers similar or
better parameter choices than the normal (non-linear)
RAW files are capable of. As you can see below there are
two different sets of output available.
1.
sRGB:
Optimized for web or monitor presentation output.
2.
Adobe RGB:
a larger color-space gamut. The preferred choice when
printing your images.
As an example, check out the options of the new D30
- LPbatch:
Everything
is automated for you!
LPbatch
offers four levels of saturation.
However, it does not use the usual Photoshop saturation
features that have been known to shift colors and increase
noise and artifacts in images. The new saturation increase
technique used in this action is a unique concept. It
works in 16-bit mode and there is NO color shifting or
noise/artifact increase. In addition, there are four
levels of sharpening. The sharpening algorithms
are sophisticated and sharpen your images without noise
or artifact increase (and they are FAST!). This results
in cleaner and more natural looking images.
Here
is an example of the D30 LPbatch
example workflow:
1)
Shoot with the D30's Auto WB or
CustomWB setting and RAW
mode. Other White balance presets are ok, as long as the
colors look accurate.
2) Batch or individually
convert your RAW files into "Linear"
16-bit Tiff files.
3) Open Photoshop and click
on File/automated/batch.
4) Choose the source and
destination folder. Also, choose which parameter (saturation/sharpening
setting) for the batch. (Normal saturation &
sharpening are the defaults).YOU
ARE DONE!
Photoshop is capable of batching hundreds
of images. As an alternative you can also edit
your images individually by pressing play on your parameter
choice (explained in the included step-by-step tutorial).
