The latest version of the Marvels Cine picture style for Canon HDSLR cameras is now out of beta and available on the blog of Marvels Film.

They have dedicated a “sticky page” to the subject: http://marvelsfilm.wordpress.com/marvels-cine-canon/

A bit more about the new cine style picture profile v3.4 for Canon HDSLR cameras.

Martin Beek, who works as DP for Marvels Film, has approved my new picture style that i’ve devised for them. They requested this new version (as you can read in a previous article) because they did not like using the Standard profile as a base for the v.3.3 style. I’ve changed this to using the Neutral style as a base for the new 3.4, but that meant that i had to change A LOT about the curve and redo all measurements and tests. This Marvels Cine Picture Style 3.4 (a.k.a. Advanced Flat) will be used to shoot a indie feature length movie. This movie is a Dutch/Italian co-production and a lot of footage will be shot in Italy at the end of this summer. Looks and moods have been taken into consideration with this style, combined with all the pros of the default Marvels 3.3 style regarding “flatness” and skin-tone reproduction.

I have shot and posted a short test movie for both Marvels Film and you all, to see how it behaves regarding skin tones. Remark: skin looks a bit near blown-out on the right of the face in the graded version, but this is due to a gamma lift or broadcast-safe mechanism caused by the Youtube upload. My original seems a tad darker and less amplified than the Youtube result.

Martin Beek has translated and edited my German instructions and explanations to him as follows.

(About the test movie on Youtube) Right image is unaltered image from camera (5Dmk2) using the Marvels Cine 3.4 style. Left image is after some simple contrast adjustment, no color grading. The last “bonus” part is a run through Magic Bullet Mojo.

 
The original image was white-balanced manually on a reference white card, but my camera has a slight shift to orange, that i have to correct in-camera one of these days, for the rest you can see that this new picture style offers the best skin tone rendition of all flat styles we’ve came across including our own previous styles. No “plastic skin” or other artifacts.

 
The style differs from the standard Marvels Cine 3.3 in two ways. This style is using the neutral style as a basis instead of the standard style. This is a setting that can easily be changed in-camera to personal taste. Further and most important, Jorgen Escher has delicately changed the curvature of the S-curve in such a way that the 65-75% luminance range, where among others skin tones live, remains linear and not curved. Some of you will notice that this was already a feature of the current 3.3 style, but since this profile is using neutral as a base, we had to adjust the curve.

 
This is NOT a replacement for the standard Marvels Cine 3.3 style, that can be downloaded here:   http://mediatube.marvelsfilm.com/marvels_cine_v33.zip
This new v3.4 is an addition or alternative to v3.3 for those that don’t like the looks of the v3.3 in regard to orange/yellow skin tones.

 
IMPORTANT: Canon L glass AND the Canon DSLR cameras all tend to lean to orange/yellow. This is not a flaw of the Marvels Picture Styles – pick a raw image for inspection and see for yourself. We can only try to prevent further amplification of this hue in our styles by keeping the skin-tone luminance range linear and untouched.

Remark: see update above.

I am in the process of developing a new picture style for the Canon 5D mkII camera, that will be used for a new feature film DSLR production. Base of the style is the Marvels Cine 3.3 style, that i’ve developed for Marvels Film, using my own tools (instead of the Canon profile editor). It is NOT a replacement for the renowned Marvels Cine style, but a new experimental version that will be used to shoot early-autumn exterior scenes in Italy this year.

If you live and shoot in a less-grey/blue environment than northern Europe, consider using this style instead of the Marvels v.3.3.

New in this version is a slightly altered s-Curve to provide better luminance linearity in the 65-75% range (e.g. skin tones) and uses the Neutral style as a basis, instead of the Standard style as in the Marvels Cine v3.3 style. This to move the overall tone a bit more to green instead of the pronounced orange skintone look of the Marvels v3.3.

Everyone is invited to download, test and use this new profile. Please check back regularly if you want to get the eventual release version.
Any comments, testresults, raves and rants are much welcomed..!

I normally don’t like doing this, but i am going to quote a weblog article by someone else. This was a comment on Martin Beek’ s blog article about a Canon Picture Style that i found specially interesting:

I personally have stopped using it (HTP) because it produces vertical banding noise (pattern noise) with almost any ISO number, under some specific conditions. Philip Bloom also reports that he stopped using it. Probably because it produces unpredictable results that are not easy to detect on-set.

HTP further limits your ISO range and gives you an extra amount of noise. Remember than Highlight Tone Priority (HTP) is essentially underexposing all your photos by 1 stop. ISO 200 with HTP is essentially an underexposed ISO 100 RAW data pushed up to look like ISO 200. That’s how it preserve highlights. You’re essentially pushing an underexposed ISO 100 RAW to look like ISO 250 in that image (since you raised exposure in ACR another +1/3 stop).

I personally don’t use HTP as said, but i follow another rule of thumb as an alternative, specially for commercial work that doesn’t allow for experimenting:
1 – use ISO 160, 320, 640, 1250 and 2500 for low contrast / low light shots
2 – use ISO 200, 250, 400, 500, etc. (ISO 100 and 125 are on their own) for well lit / high contrast shots

1, because the broken ISOs have considerably less noise, but also have less latitude (highlights clip at raw 12650)
2, because the whole ISOs have more noise, but retain highlights much better (highlights clip at raw 15300)

Together with Marvels Cine 3.3 this will make your day… ;-)

Cheers!

I think that Martin is mostly right, although i have to look up and compare the numbers he quotes. I must add one important remark: this is typically targeted towards shooting video, not RAW photography.
