Magic Bullet Overexpose Sky Why?

a similar querie was made but i didnt get the answer i was looking for..
its not about preproduction set design, lighting, framing and picking out object's/colors that contribute to film look.

the main criterion of concern is when making a comparason of a frame between a shady grey sky pre and post with magic bullet.

the original image has much detail of the grey cloudy sky.

the image with magic bullet (no matter what preset i use) overexposes the grey cloudy sky leaving hardly any detail of the fluffy nature.

the preset i mainly start off with is the most subtle "basic" then i back away some features (that helps a little) for more subtlety.

now, im aware that contrast ratio of video is not equal to film, however, there is much detail of the sky in the original footage to begin with, so why is it overexposing sky?
 
I am unable to produce the problem.

I have an image that includes a dramatic grey sky that has a full tonal range .

MBs as presets are able to hold detail in most cases and MB Editors can tweak the sky detail to anything I want.

I saw your previous post. I do not consider that MBs are trying to create the much maligned and mis used term "Film Look".

They create "looks".
 
Sometimes the magic bullet "Looks" presets do completely kill the sky, i have seen this. I think "Editors" probably gives you a lot more control over your settings so that is avoidable. You could maybe try a matte or something to save your skies.
 
hi Shooter, for some reason it does not happen with all shots.., but it does happen.

LDP, hi. what do you mean by matte? sorry im still learning and have not picked up on all aspects of NLE.
i think i know what youre talking about.. if i do what you suggest, a matte to save the sky. and lets say there is a plane in the picture with the same color as the sky.., will the color of the plane be in the same channel as the sky?
hope that was clear.
 
magic bullet often pushes the contrast of your shot and often raises the levels of the bright portions of the image beyond or close to the point of blowing out. you would have to reduce contrast or make a levels adjustment to keep it all in the range you want.
 
or use a compositing software / good editor to isolate the sky (mask) getting more control... any glow will over exposure a bright sky, and glow helps a lot in the film look generating a small halo on bright areas, something like a promist filter.

hi iamloser.
so its not just me then, thanks for the tip.

ulisses, hello.
can you please point out to me an example of a "compositing software", and the "editor" to isolate the sky for masking.

currently i am only using vegas5
 
I hope any compositing software does masking, I use Digital Fusion but After Effects does it.
Vegas5 has masking / color correcting, I'm not a Vegas user, I only did some tests, but there are many people here using Vegas and even a vegas forum :)

Skys are very easy to over expose during the shoot but in saying that I find the DVX extraordinarily good in handling theml. Basically it is why I have and use only two filters for my DVX.

A polariser and a grad ND. Both these effects I think are impossible to achieve convincingly in Post. Once the sky is gone it is gone ( eg. no detail to work with)

A recommendation before applying Magic Bullets is to do a CC grade first and it is important to get a full tonal range from your original (especially the sky). Do not over do the CC (colours) if you plan to use MBs. I use the levels control, gamma and HLS.

Another thing I do is always grade tones (in B&W) first. Its a colorists trick that works very well.
 
thanks Ulisses, i guess there are so many features i am still oblivivous to.., maybe i should look out for a good comprehensive video tutrial.

thanks Shooter, excellent tips man, i wonder if those filters are easily attachable and detachable? either way that would be the perfect trick tip, thanks.

i still gotta find out what CC and HLS is before i go any further. and thanks again for the colorists trick.

cheers guys.
