An
alternative low cost solution are the generic 3D LUT's derived directly from
specific systems like Apple's Mac's. These 3D LUT's are created on order and are
specially crafted to perform on very specific setup's.
We
can provide LUT's for the following Mac's running 10.6.3 and above:
-
● Mac's that
using Apple LED Cinema 27" connected with display port, that is all Mac Pros,
-
iMac's, Mac mini and Mac Books.
-
-
● iMac's with the
LED Cinema 21.5" or the 27" display. (Coming soon)
-
-
● MacBook Pro with
the LED 15" or 17" display. (Coming soon)
All systems are not available today since we are in the process to add them
check the order now page to see which are available for order in the drop down
buttons on the buy now area.
These LUT's are coming with specific instructions for Apple Color on how to setup your machine and
get the result. The LUT's are meant to be used for non critical preview and will
might have an error of +/- 20% if they used on the correctly setup machine.
Conversion LUTs are designed to convert a film target to the appropriate digital
target.
Also we are providing Camera LUT's for ALEXA Log-C, Sony S-Log, Viper FilmStream
and we can provide for Panasonic FilmRec. For the use of these LUTs in the tech
papers area their will be a document that will explain the various
workflows.
Additionally a Cineon Log 6500K (HD), 3DLUT would provide a much better result
when used in high end Color grading systems like Apple Color and DaVinci than
what the simple curve that Technicolor includes in the package for the Canon 5D
Cine style.
There aren’t available LUT's for all the cameras are today, please don’t
hesitate to ask us using the contact form on the left.

FAQ for Generic LUT's
Q. That means we
will get 3DLUts for everything like Film, DCP- XYZ, sRGB etc?
A. Yes, that's
the point, we can provide LUT's for almost all the targets available under the
price of 30 euro's each.
Q. Do we need
extra hardware to get the LUT's?
A. No,
these LUT's are coming to you with no profiling so no hardware is needed apart
from the appropriate Mac.
Q. If we don't
use a Mac's, can we still ask for LUT's?
A. Unfortunately
for now we don't have this option, you can send us a request by using the
contact form from the side menu and we will evaluate the possibilities.
Q. We do have a
MAC
color grading system, not Apple Color, can we order LUT's?
A. Unfortunately
not for the time being, the reason is that we have optimized the result for
applications using the secondary monitor as grading monitor. Apple Color is
doing that, if you use another app. that uses the same functionality you can ask
us.
Q. Are you
planning in the future to support apps that using Video out as grading monitor?
A. We are looking
on supporting HP DreamColor and a specific LG monitor, the LG
W2420R both connected with HDMI Black-magic video card. This will cover DaVinci as well
as some PC app's. We don't have dates yet, but the support is coming.
Q. We have
a monitor that we trust, can we work with that?
A. Unfortunately no, because
these generic LUT's are created to be used with very specific hardware not all
monitors are good. You can use a generic LUT to a good monitor but the result is
unknown. Alternatively you can choose the Student or Cinematography support
package that covers all monitors capable to perform.
Q. Ok, let’s
assume that we going forward what is the expected accuracy?
A. The accuracy
that we aim is less than +/-20%.
Q. What are the differences between what you do and Magic
Bullet LUT Buddy free?
A.
Let’s explain the different types of LUT’s existing to
understand:
-
Viewing
LUT’s, these are LUT’s that can be created from special software like
CineSpace with the aim to calibrate accurately your display devices to
certain targets like Filmout Stocks, DCP, REC709 etc. These are our Generic
LUT's.
-
Looks LUT’s,
these are LUT’s to take an A image “original” that you will alter it (color
correct it) to an image B “new image” and because you want to transfer that
Look to other applications you will need to create a Look LUT which when it
will be applied to images it will convert them from Look A to the Look B.
-
Conversion
LUT’s, these LUT’s are designed to take a given color space like a given
Film Stock or Cineon Log to REC709 or DCP, these LUT’s can be applied in the
video output and used to color grade a Log sourced image to REC709. You can
find this type of LUT's in our Gneric's.
The first is
needed to bring your viewing environment to an accurate state in order to have
the confidence of what you see is also visible to your clients and to the world.
This is a difficult and very expensive task to achieve, it needs special
software that costs more than 1500$ and up, plus probe and monitor that can
perform. Have in mind the package needed isn’t the typical Desktop Publishing
monitor icc calibrators but rather the cinema counterparts that supporting 3D
LUT’s. This can be covered along with the third in the most cost effective way
by using our consulting services. Alternatively you can use our Generic LUT’s
that are used with specific setups to get a similar result.
The second is what the Magic Bullet free plug-in is doing…
So the bottom line is that you either need a correct conversion LUT to work with
Log and i.e. with the new Technicolor style like the REC709 to Cineon 6500K (HD)
assuming that you use an averagely calibrated HD monitor or if you want a
professionally accuracy you have to use the professional tools to calibrate and
the appropriate monitors.
Q. Ok you do different thinks, but Technicolor provides a
LUT with the package what is the difference?
A. The difference is that the LUT’s included on the package
are just simple 1D curves in 8bits and we provide regular
high precision 3D LUT with 12 or more bits in depth that
allow you to take advantage of the internal Floating point
color engines of Apple Color or DaVinci i.e. in a way that
will result in much more rich image and more flexible. As an
example the Technicolor LUT is 4k bytes and a DaVinci 3D LUT
for Cineon Log 6500K (HD) is 951k bytes.
Q. Can After Effects work with 3D LUT’s?
A. As for After Effects the most current version CS5
(10.0.1) supports the Autodesk formats of *.3dl, which we
can also provide as generic or conversion.
Q. Why the Log is so better than linear in small cameras
like canon 7D or 5D?
A. Let’s assume that we want to capture an 8 stops image
from a sensor that has 12 bits internal processing that’s
4096 steps of light intensity to an 8bit compressed H264
file that’s 256 steps.
In “linear” the top brightest stop n. 8 will consume 128
steps, the stop n. 7 will consume the next 64 steps and the
stop n. 6 will consume the next 32 steps. The top 3
brightest stops of an image when is being described in
linear will result to “consume” the 87,5% of the available
bits in a file, leaving the lower 5 stops of the
mid-tones/shadows to be described by just 32 bits…!!!
On Log we allocate 10 stops in equivalent segments like 25
bits for each stop. That results to a secondary data
compression of an applied curve, which needs to be
decompressed with the use of an appropriate 3D LUT in order
to counteract accurately also the saturation of the
converted image. By doing that we effectively recreate
information that wasn’t visible in the original file but was
there in the original image the sensor was capturing.
So the difference between Linear and Log is night and day.
