The Power Of Color Grading And The Benefit It Can Have On Your Work

by David Geffin

If you aren’t applying any color grading to either your photographs or motion work, you are potentially missing a vital part of the process of finalizing your image. Color grading can be one of the most impactful tweaks you can make to your work once it’s been shot. It has the potential to elevate a good image to great, or a great image to outstanding. This short video and article highlights why it’s so important and the powerful impact it can have on your work.

This little-over-two-minute-long video shows excerpts of the independent movie, ‘The House On Pine Street’. The film was graded by Taylre Jones at Grade, and he’s demonstrated brilliantly how the original footage stacks up against the color graded footage looks compared to it. If you’re in any doubt over the power that properly grading your work can have, you have to check this out.

NEW TECHNOLOGY FOR COLOR GRADING : THE NEXYAD SKINS

(French Version)
NEW TECHNOLOGY FOR COLOR GRADING : THE NEXYAD SKINS

by NEXYAD



INTRODUCTION
The digital post production has merely reproduced the old post production phases, using software whose
interfaces were comparable to those of physical machines previously used.
Eg interfaces using the « slider », the « button », etc … all of which were essential to set an analog electronic
machine or a mechanical machine or mechatronics.
But digital also allows to completely change the way of thinking and will soon revolutionize workflows in
post-production film and television.
Indeed, suppose that there are two control buttons on a machine (eg overall luminance and overall contrast),
we can draw this:
Luminance & Contrast
The rectangle materializes all possible settings of the image using these two buttons which can rotate independently of one another.

« Turning the knobs » to go from one setting # 1 to # 2 setting means « moving » in the diagram:
Contrast Button

With digital technology, one can easily reproduce this mode, but you may also « pave » the rectangle with
predefined positions that have been judged as « interesting » by experts and then « jump » from one position to another:
Contrast settings

One can imagine letting the user move in « button mode  » around predefined positions … Then all areas of the rectangle can be achieved, but preference is given to Presets which has already been validated as aesthetic.

This means that instead of « moving » continuously from one setting to another, we now « jump » from one setting already validated to another validated setting.
Advantage: jumping does not go through the settings which lead to unpleasant images, one goes straight on already validated settings.

CRITICISM OF THE METHOD
It can be argued that this approach is to spend « tailored » to the « ready to wear ».

Yes, but for those who do not have the budget to pay for custom-made, the solution is very inefficient: you’ll see a poor tailor who certainly takes your measurements, but then is not very well paid for quickly making a bad cut in poor tissues, and your suit at the end is not very beautiful.
You have the illusion of tailor-made, but you do not have the budget to turn the knobs very far.

In a « ready-made » solution, if the number of different costumes for sale is very large, in one hour you try dozens. It is much more efficient and cuts can be very sophisticated because stylist work cost was made one time for tens of thousands of customers.
Our response therefore is to know where you are in the chain of budgets : low ? average ? high ?
Furthermore, nothing prevents you from taking the ready to wear and do everything custom touch then.
Our solution is optimal in terms of price / quality ratio.

Moreover, the argument of « creativity » clamped is also very questionable: when one has no budget to work for a long time involving global experts of the field, then, turning knobs, and even if the result is aesthetically acceptable, it is likely to be find a result that is already known and already used repeatedly by other filmmakers.
This is not because we do not know anything that we are original. The application of N color grading (example: twenty) on your film, even if it is only to « see », will help you do your own way and making sure you are original.

EXAMPLES OF NEXYAD SKINS
The images below are presented for illustration. With NEXYAD SKINS, you don’t need to know how the images were initially, simply look at the end result, choose one that you like, and you can get it on your own images.
This is a revolution in post-production. Here are the first skins that NEXYAD has developed :

NEXYAD Skin « Golden », an automatic color Grading for your films, videos, TV shows and pictures.

What is a Nexyad Skin ?
The Nexyad Skins are based on a high technology combining image analysis, human visual perception analysis, image processing and color theories of great picturial movements. Whatever the incoming images (rushes or already modified) the application of our Skins generates a final rendering with the selected colors positioned where we wish.
Our skins are not LUT and it do not need any human intervention.

Automatic color grading and calibration Nexyad Skin « Golden » put on again a classical. Some famous filmmakers use yellow or golden to warm scenes up. For indoor scenes, this suggests a late sunny afternoon or the flame of a fireplace and gives an happy and comfortable atmosphere. For outdoor scenes, it can be used easily in a more monochromatic way because in sunset everything turns gold sometimes.
Whatever, this grammar of color grading tends to give a powerfull and rich effect to images as the pictures below from « The Lord of the Rings ». In Luc Besson’s productions, we seen lots of scenes in Yellow or golden tints.

Fully Automatic Cameras Fitting

NEXYAD Cameras Fitting, an automatic tool to fit several cameras for your movie, videos, TV Shows and Pictures.

It is common those days to use different cameras to shoot your images. Maybe is there a second film crew that make shooting in other locations, maybe it is handy to shoot short clips from different angles with low cost cameras, maybe main camera have a problem in the middle of film set, etc…
NEXYAD has developed a unique tool to fit in an automatic way images of different cameras. In the following demo, we used the interesting work of Geoff Boyle’s team. In a recent CML test (the Cinematography Mailing List) they had the good idea to use single subject with test patterns to compare twelve professionnal cameras : FIND CML UWE 2015 TEST HERE.
Many thanks to CML for this opportunity to show our tool Cameras Fitting.

We can see obvious differences between the two images with a short look in terms of colors, dynamic range in dark values and signal to noise ratio. Take a closer look on some patches of the first lane in target patterns on the right side :

Now see the same patches comparison after the NEXYAD Camera Fitting :

The results are pretty close, isn’t it ?
Of course, some values in the dark are crushed in the BlackMagic and it is not possible to fit 100%, plus the problem of SNR that is not equilavent for both cameras. However, most of the colors and luminances were transformed from an image into the other one without any human intervention but with powerfull maths algorithms.
