Secondary Color Correction in Combustion

[kk01]

1. How can I setup a secondary color correction workspace in Combustion.

Please dont forget that I have to do some primary color correction first before doing a secondary ccorrection. Which means I have to setup a primary workspace before a secondary workspace.

Coming from an AE stand point of view, using the pen tool/mask tool is pretty easy, but in Combsution, it has some pretty funny masking tools…

2. …which will you say is cool secondary color correction…

3. I dont know if this possible in combustion and that is, most editing and color correcting systems/applications come with a 3 way color corrector (lift, gamma & gain)…can I create this workpace…if I can please give me a clue.

If I must add, the Combustion GUI is pretty…it’s only quirky geeting around…

hi,

if you are on C2008, the colorwarper is what you might looking for.
if you don’t have this version, or don’t like to upgrade, secondary cc is pretty much just choosing and seperating a hue and change its properties. in combustion you can use the discreet keyer, set its output to selection, after the keyer node use your cc tool of choice and use a remove selection op to kill all prior selection. in short for secondary cc use a keyer and a cc op.
also, you might want to make yourself comfortable with combustions schematic view. it is easier to keep track of branching off things.
also, for render speed reasons, try not to make too many nestings. they will slow things down.

best,
rayk

thank you very much for the tip RayK…I dont use Combsution 2008…still on Combustion 4 and as you have mentioned, this can be done with a Keyer and a CC operator.

I have never come across this before so I’ll ask…how do I set the Discreet Keyer output to selection as you have mentioned in your message…

Will be glad to read from you soon…:confused:

add “discreet keyer” – go to keyer controls – “setup” (left side) – goto “output matte as” (right side)
or
add “diamond keyer” – output tab – “output matte as”
or
use the alpha, produced by the keyer in combination with a “channel selection” operator, or with a “compound selection” op
… you’ll get the idea….

thank you very much RayK, I’ll give it a shot right away…I hope I dont have too many problems along the way…(lol!)..;)

Now my question now is, how do I maintain skin tones RayK…

Take for example, I want my shot to have this overall tone of the hue blue. First of, what I’ll do is to first balance my the shot…afterwards, I’ll apply a solid blue layer and maybe use a multiply or overlay transfer.

Now, my shot should have an overall blue tone…but what do you think I can use to keep that skin tone in the shot… :confused:

Try a selection mask.

… use another CC op …

you could also try the color suppression op (in the keyer section) …
say, you wanna have a blue tint, you could raise the blue curve for all hues, but keep the blue curve points in the reds low … just play around with it and see what it does. maybe it’ll suit your needs.

have fun.

thanks mate…I’ll hvae to try but I have an idea of what I wana to achieve so this should help…thanks alot…after doing doing…I’ll post links to some shots I practiced with…:rolleyes:[/SIZE]

After trying so many options in Combustion, I still finding it difficult to acheive the shot I want. After so much confusion, I then tried acheiving what I wanted in Photoshop and if you visit the link below you’ll be able to have an idea of what I was trying to achieve in Combsution.

Can someone kindly take is or her time to explain how I can do this in Combustion…I’d love to learn and also for experienced Colorist in this forum…can you please tell me what’s wrong with the final shot in the zip file you are about to download…

Will be glad to read from someone soon…:confused:

PS: Please not, I am using Combustion 4.0 and not Combustion 2008.

quick reply…please

[karan]

pardon my way of replying, but you do exactly the steps you did in photoshop. the filters/operators may be named different, but everything else is basicly the same. only, but big, difference is that you need to animate your selection, in case you don’t like to branch out, or you use a keyer to key out the faces in a second branch and use a “compound selection” together with the matte generated by the keyer, or you simply invert the matte of the keyer and put the faces in top of the graded layer and grade the faces to your likeing.

reading your original post again… in ae you would draw a mask to hold out the blue tint?
selections in combustion do the same. you can draw them or you can create them by using procedual methods like keying or channel manipulation. just look up “selection” in the help files.

[Googly Mania]

…I think I’ll do just what you have written…I mean, I’ll check the help file on the topic ‘Selection’. I guess this is my problem…I think the reason why this is happening to me is because I am still very new to using Combustion…

Thank you very much RayK…
