Channel Mixer (was Peggy6612)

Does photoshop elements 12 have a channel mixer for doing infrared photography?

No, but there are several add-on toolsets (both free and inexpensive) that you can install that will add this ability. Grant's tools, for example:

  • Compositing - Channel Mixer Help

    I've been using AE now for a few years, (since v5.5) and mostly use it for motion graphics. Using CS3 now. But right now, I'm beginning to work through Steve Wright's book, <a href="http://www.amazon.com/Digital-Compositing-Film-Video-Second/dp/024080760X">Digital Compositing for Film and Video</a> to focus more on true compositing.
    The author's aim is to keep the lessons application-independent and present concepts in a way that would be applicable to most software packages. (However, considering the author's frequent references to "nodes" and his well-known status as a Shake user & <a href="http://movielibrary.lynda.com/html/modPage.asp?ID=408">Shake instructor</a>, it's apparent that using Shake, while reading this book, would lead to the least bumps in the road, when attempting to follow along.)
    But I'm not using Shake, I'm using AE and have encountered a small bump in the road. Regarding luma keys he mentions how luma values are represented in the individual colors R,G,B. To cut to the chase, he says, "One standard equation that mixes the right proportions of RGB values to create a luminance image on a color monitor is:
    Luminance = 0.30R + 0.59G + 0.11B"
    Great. But I can't figure exactly how to mix the RGB values with the above proportions in AE. It's quite easy & straight-forward in Photoshop, using the Channel Mixer. <a href="http://www.geocities.com/kevincbrock/channel_mixer.png">Example here</a>. But AE's Channel Mixer does not seem to work quite the same way as it's counterpart in PS. There are values there, for instance, "Red-Red", but they seem to run in values from -200 to 200, not percentages, like PS. So my question is, how do I achieve the same channel mixing results in AE that I can in PS?
    I'll add this: I was able to achieve the desired result in AE, but by using a round-a-bout sort of tactic. Instead of using the "Channel Mixer", I applied the "Set Channels" effect to my sample shot. By changing the "Set Red to Source 1's LUMINANCE", then doing the same for Green and Blue, setting them all to LUMINANCE, the resulting image is identical to the sample shot that was tweaked in Photoshop. Again, it worked, but I'd like to know how to change the proportions of RGB to other values than those represented in the formula above.
    Hope this all makes sense.
    Oh, and while I'm here.....I'll throw this in: In AE, when you apply the "Curves" effect, can you input precise values for input / output. Again, this is simple in Photoshop, but unless I don't have some display items turned on in the Curves editor in AE, I don't see a way to enter precise values. Is this possible?
    Thanks in advance for any input.
    EDIT: for some reason, the links I've posted aren't showing up properly. So if your'e interested in following any of them you'll have to copy/paste on your own. Don't know why......

    >Great. But I can't figure exactly how to mix the RGB values with the
    >above proportions in AE.
    You could use expressions... You create sliders for each input, then feed their output to the actual effects. Something like
    //----begin expression
    linear(value,0,100,-200,200)
    //----end expression
    should do in most cases. Still, be careful. Not everything written in that book directly applies to AE. It does not figure in any specifics of color management nor different Gammas which could massively skew results because the source footage will already be pre-adjusted and the comp will add another level of adjustments.
    >Oh, and while I'm here.....I'll throw this in: In AE, when you apply >the "Curves" effect, can you input precise values for input / output.
    Nope. AE's Curve effect will adapt to the project bit depth as a lot of other effects, presenting you with the problem of which values to actually use. This would only make sense if the effect itself would be independent from AE and process in float all the time and only the inputs were presented as different normalized ranges. There was/ should have been an alternative Curves effect from Frischluft, but at this point development has reached a dead stop, so it's doubtful it will ever be unleashed upon the world.

  • Desaturate and channel mixer

    Hi, I have a clip that I have made b&w by applying colour correction and dragging the saturation to 0. I was wondering if someone knows what RGB channel mix does FCE use when we do desaturate? I tried replicating the same with channel mixer and changing the R,G,B value with monochrome ticked but could not arrive at a set of values that gave the same look as desaturate?
    I'm using FCE 4.0.1
    thanks

    I know of the desaturate filter and the monochrome option on the channel mixer.
    The reason I am playing around with the channel mixer is because I am not entirely happy with the b&w image that gets displayed. Because of the way the shot was taken, I expect there to be more information in the red and green channels and which is why I am trying to adjust them and get the right detail and contrast.
    But as I do that, I was wondering what formula does final cut use when you apply desaturate. In the background, it would also be adjusting the red, green and blue channels? Right?

  • Channel Mixer Tutorials/Book woes

    For my class ( I have a student assistant position) we bought the new CS4 book, (Studio Techniques) and it doesn't come with a CD, which means no pictures or files. We are having trouble with exercises for the class and  was wondering if anyone had found a good book out there, that comes with a CD?
    _We are also looking for a Channel Mixer Tutorial, something with real world application that will help the students get the most out of the channel mixer.... any ideas?

  • CS5: Magic Wand fails intermittently; cannot use Channel Mixer on selection

    Hello,
    Using CS5 / Photoshop on Mac OS 10.6.4. 4GB RAM.
    The Magic Wand tool fails intermittently.  Quitting PS and rebooting seems to re-enable use of the Magic Wand.
    However, even when the Magic Wand tool does "work", for some reason I can no longer use any of the items in Image -> Adjustments, such as the Channel Mixer.  This functionality was working just 20 minutes ago, and now even with multiple reboots I cannot seem to get it working again.
    Googling came up with no relevant articles on this errant behavior.
    Any help is greatly appreciated.

    Could you post a screenshot?

  • Four channel mix for P2 format?

    I'm in the final stages of editing an EPK for an upcoming indie film, but I'm having some problems getting the audio output the way it's supposed to be delivered. The distributor wants the EPK on a master tape with a four channel mix. The problem is getting it to render it out that way.
    We shot the EPK on P2 cards (720p), although the finished cut, while predominantly made up of P2 footage, also contains quite a number of production stills, SD footage and clips from the finished film sourced from the final Quicktime render file. Now the producer suddenly decides he wants me to export it as an MXF and put it on a P2 card, which he can then take to his people and have dubbed to HDCAM.
    But, even after reading the CS4 manual, which seems to indicate that you can export back to P2 in four channels, I can't get it to work right.
    I thought it was because I hadn't set up my sequence timeline for 5.1, so I created a new timeline as a 5.1 output. Then I had trouble porting the clips over to that because of memory issues (big project), so what I decided to do was export the project timeline twice as an MXF sequence. The first time I muted the tracks which had the music and effects on them and exported just the main program. Then I muted the main program audio and unmuted the music and effects and exported again. Then I opened a new project with a sequence that was set up for 5.1. I laid down both exports on the time line, the two video tracks right on top of each other. Then I used Source Channel mappings to route the main program to channels one and two, and the music and effects to channels three and four. I played it on the timeline and saw four channels light up with the mix.
    So thinking I had solved the problem, I exported it again as a MXF and examined the output - only to find that the new sequence was only two channels, and only the main program audio. The music and effects were nowhere to be found.
    Anybody know how to get this to work? Thanks!

    Unfortunately, unless a software CD-4 demodulator exists that can process "modulated" recordings (it might...), you'll need 4-channel hardware capture capability.  This is pretty common for musicians and you might find solutions in the music equipment section of Best Buy.
    In terms of software - Audacity is amazing and VERY powerful.  One thing you might be able to do with Audacity is something like:
    Record player -> CD-4 decoder -> 4-channel audio capture card/interface -> 4-track WAV file
    then
    4-track WAV file -> 4.0 or 5.1 channel AC3 (Dolby Digital) audio -> Dolby Digital capable surround receiver
    The latter is actually what I do with recordings from my Zoom H2 - however this has 4-channel mic recording but not 4-channel line-in recording.
    It looks like, in order to do software CD-4 demodulation, your recording solution will have to have a VERY high samplerate and a much higher cutoff for its lowpass filter than typical for audio - there are likely to be few off-the-shelf solutions for recording the "un-demodulated" CD-4 inputs.  http://en.wikipedia.org/wiki/Quadraphonic_sound#CD-4_.28Compatible_Discrete_4.29_.2F_Quadradisc - In short, I don't think recording to PC and then demodulating is going to be practical.

  • CS6 channel mixer misbehaving!

    Can someone help with my problem please? I export a photo to CS6 and use channel mixer to swap the red and blue channel values i.e red from 100 to 0 and blue from 0 to 100
    which should give me a blue background for infrared photos then for further PP but it is giving me a green background instead and nothing has changed it has just decided it wants to act strangely
    I do have malware on my macbook pro retina so Im wondering if this has something to do with it? Would be great full if someone has any clues?

    With the channel mixer to swap the Red and Green channels:
    1. Select Red for the Output Channel
        Change the Red to Zero (0) and the Blue to 100
    2. Select Blue for the Output Channel
        Change the Red to 100 and the Blue to Zero(0)
    You could also save the settings as a preset so you don't have to adjust the sliders everytime

  • Curves or Channel Mixer - which is better?

    Which do you think is better for colour correcting/adjustment (especially CMYK images)

    When you add up the ink percentages of your four ink colors - Cyan+Magenta+Yellow+Black, you'll get your total ink density, which is what I'm sure Alan is referring to. Set one side of your Info Palette to read Total Ink, and then you'll easily be able to monitor that. If you have too much ink density, magazines are very likely to kick your file back, asking you to fix it, making you miss your deadline. If you have too little ink density, your blacks may look weak.
    Alan is correct, Curves, Hue/Saturation, and Selective Colors are the first choice tools for CMYK color correction and Channel Mixer is usually for making huge fixes which will usually require Curves to bring back into line anyway.

  • How to become Channel Mixer

    Hi everybody
    I Have Photoshop Elements 5 and I would like to upgrade it to a later version. Now I need to know if PSE 8 would have Channelmixer, which I need for my work. If not, can I upgrade to a Adobe Version with Channel Mixer ? And how can I do this ?
    Thank you for some advice !
    Hanny

    Can you point me to where the $299 upgrade to CS5 from PSE8 offer is located?   When I
    go to the Adobe store and specify an upgrade from PSE8 to CS5, the price is $599.  $199 for CSx to CS5,
    but that does not help me.   Did this promotion end, or am I missing something?  Do you happen to know how long the offer will be on the table?

  • Missing facility: graphic channel mixer

    Hi Guys,
    I miss a graphic channel mixer so that I can reduce channel separation in
    problem zones, primarily the bass range when handling vinyl and shellack,
    but there may also be benefits for similar processing in the treble range.
    Kind regards

    In the arrange window, check to make sure the check-boxes have been checked to display sends,pan etc etc etc.

    How I can create channel mixer by JavaScript?

    If you create a channel Mixer script you will most likely be using Action Manager Coder you modify from Adobe Scriptlitener Plug-in.  There  is a Photoshop scripting forum and scripting documentation you can download. Adobe DOM does not cover all Photoshop function.  Adobe Photoshop Scripting | Adobe Developer Connection  and Photoshop Scripting

  • Transpose PS Channel mixer values to LR

    I use presets of channel mixer for converting images to gray. The presets I have are based on RGB Values. How can I transpose that to the 8 channels on LR ?
    In addition to transposing from 3 to 8 channels, I see that moving 3 channels to 0% make a black photo. When all sliders on LR are moved to -100%, the gray shades of original photo are not modified.
    thank you for your help.

    You should try it and see the effect I am describing for yourself. Noise reduction is not helpful. When channel mixing is done correctly there is no need for noise reduction. The high-res sliders in Lightroom and ACR, though, do not do channel mixing. They operate on specific hues and can't be used as an equivalent to channel mixing no matter how you move them around.
