Photoshop :: 16bits/channel Multilayer Psd File...
Dec 3, 2008
Did someone already know about 16 bits/channel multilayer psd file parsing is different to that of 8 bits/channel multilayer psd file?
as far as I try, it seems 8 bits/channel model, image data is saved in RLE model, but it is quite different in 16 bits/channel,
we could easily find out once we load those two file into memory (with same context, only model changed).
Anyone who know which algorithm may 16 bits/channel multilayer psd taken for saving the layer image data?

following the Action Workflow pt 1 tutorial with my own footage.
1] I have a background track and green screen track above it. I apply timeline axis effect Master Keyer and create an awesome key.
2] I select both layers and create CFX. My awesome Master Keyer key is now changed back to a a luma key or something.
3] I go into Action, select media and click on the K in the media list. In the lower left of the screen the following message flashes quickly (I have to click many times to read it. It doesn't stay on long)
"16bits FP not supported"
4] I note that both my background layer and my foreground layer say the following [12->16f) I think that means 12 bit is being converted to 16bit. Not sure why. I never asked it to do that. So I click on the clip in the CFX schematic. I see RGB LUT is Active I change both to 10 bit. Same result. I try 12 bit. Same. If I change these setting in RGB LUT I am not permitted to leave the CFX editor, so I change back. I make sure resize is on.
Anyway, the tutorial is cool because the keyed footage just shows up right immediately upon entering CFX. I'm not so lucky.
How do I get green screen footage into Action? Bottom Layer is 1080, top greenscreen is RED 4k. Resize is on for RED footage. Changing bit depth makes things weird and doesn't provide a result.
If I hit reset in the Action node Media panel the K disappears. I can now double click on the empty space and up pops that godsend Modular keyer.

I had a sudden loss of Photoshop and need to work on a large multi-layered psd. (Had I known in advance I would have reduced the size & layer amount.) Gimp won't open it because it's CMYK.
Tried several conversion techniques to RGB, none worked well. How can I open this file and maintain the layers? Also, there seem to be several different kinds of RGB, what are the differences?

I been searching around but other than going to the smart sound website and buying their software I do not know of any other sound software which allows me to create multilayer music for video studio. Additionally it does not appear that their software contains a plugin for Corel videostudio. So what are my options concerning creating custom music for videostudio?

I am a screen printer and I print my separations from Photoshop. I routinely work with multi channel files or RGB files with additional spot color channels. I have created actions to place my registration marks, re-size images, etc to get ready to print but I manually have to create the text labels for each screen if they are missing from the original artwork.
The files I work with have channels named as "Base White, Red, Green, 284 Blue" etc indicating the ink color. What i would like to be able to do is click an action that would copy the text from the channel name and insert it into a separate or each/all channels near the top of the file so that when I print each positive it has a corresponding label for ink color.
I am not sure if this is even possible, and I am limited on my knowledge when it comes to actions and have pretty much got lucky in the past getting them to do what I want without unnecessary steps.
On my registration target action it creates a new channel with each individual reg mark then combines them into one separate channel in which I just copy the contents and select all the ink channels and fill with black to make them appear, i'm happy with the steps it takes as it isn't too much trouble and if this could do the same with labels I would be happy with that.

I'm trying to edit some map files in the game called "Farming Simulator 2013" by GIANTS. They are png files & I can load/edit the files in paint. But after I save the files back to the proper game folder & try to run the game I get an error stating :grass_weight.png' incorrect format. Must be 8bit single channel. Is there a plug-in to save a file in this format? Am I missing something or am I just not going to be able to edit a paint,net file in paint.net? I

I have a 48bit RGB TIF file, and I would like to save just one channel from that file as a 16bit Grayscale.
Having done a bit of digging, I have found numerous ways to convert the whole image to Grayscale, with varying degrees of artistic control, but nothing about ripping out a single channel.
Can it be done? How? Have I just overlooked the obvious somewhere?
I would like to do this with as little user intervention as possible as I'm likely to want to do it, in batch mode, to a lot of images.
PS: I have no objection to a solution that actually saves all three channels in one operation, each to a separate file. I can always throw away the spares.

I have a PNG file created in Photoshop and I need to save it with an alpha channel for web purposes. I tried 'Save for Web & Devices' and selecting the Transparent box.
Then, after saving, when I select 'get info' for the file it says there is no alpha channel. I'm stumped I can't seem to create an alpha channel from within Photoshop while I'm editing.

I have a multi-channel file with two spot colours. I want to convert it to RGB, however that option is unavalable - only the Bitmap and Greycale modes are available to me.
How do I convert back to RGB?

I'm trying to extract the channel information from a .psd file in binary mode. I'm able to extract the number of channels and their names, but not their types (I mean if it's a spot color channel or a mask). The documentation I've found is from 1997 and some things are not the same with the newest versions.

I've made an animation file in PS CS2. I need it to have an alpha channel, or just be transparent when I import it into my video editing program Final Cut Pro.
How do I do this in PS and how do I export it?
The file is a Lower Third - which will have titles written on it.

One project I use Photoshop CS4 for is painting aircraft used with Microsoft Flight Simulator X (FSX). Each aircraft is downloaded as a "Paint Kit".I paint and add layers onto the kit until the aircraft resembles the design I chose. The paint kit includes a background, base parts usually in white, and an assortment of layers adding physical wear, shading, lines and rivets you see on actual aircraft.
Additionally, the kit includes an RGB Alpha Channel and Specular Maps. In this application, the Alpha channel provides the reflectivity or gloss on the aircraft paint. The Specular maps provide a sheen much like the subtle reflections you see from a metal flake paint job when the sun hits it directly.
Once all painting and manipulation is complete, the kit is "cut" into specific sizes. Once the kit is cut, each section is saved as a DDS file using NVidia tools. The resulting DDS files are placed into folders within the main FSX program folder. The FSX program "assembles" the sections and processes the different layers and channels resulting in aircraft that are incredibly detailed and realistic.
My problem is I don't know how to properly integrate and preserve the Alpha channel during the "Flatten Image" and when saving the file as a dds file. As you can see in the "Layers" section in the picture, the Alpha channel is already made. I just don't know what to do with it to preserve it and ensure the reflectivity it provides is visible in the final product.
what I need to know isn't what the alpha does, but how to properly integrate it into the final product. I've searched for this info for the last several days, but I've had no luck in finding specific information on how to do that. URL....

Is there anyway at this point in time to load a DDS file with alpha set to something other than 100%, alter the alpha channel, and save it back out again?
My situation is this. I'm currently working on a module for a game called Mount and Blade Warband and have created quite a few textures using Paint.net and never had any issues previously with any textures I've created and saved as DDS. However recently I found a texture file that I need to replace with my own version which has it's alpha channel set to something other than 100%. It's used to blend with another texture to give an aged appearance to hair.
Now this texture when loaded into Paint.net appears as a mostly transparent texture, which I cannot make any darker using the layer transparency slider which is set to maximum. i.e. The texture is loaded and displayed with transparency on, but the layer transparency slider in Paint.net is set at maximum opacity as if there is no transparency -- so the only thing I can do is make it even more transparent rather than make it darker. So when I tried to make my replacement for this particular file I created my texture, set transparency for the layer to about 20%, then saved as a DDS file -- however when I load it into the BRF game editor it displays as a completely black texture, while the original file displays fine.
EDIT: Also does it actually create mipmaps when you ask it to when saving? I just noticed that my textures don't seem to have them.
I should point out that while I'm very experienced with programming, 2D etc. I'm pretty new to 3D programming (not that I'm doing so on this project of course -- thought it might be easier working out how to create 3D objects while using someone elses engine to start with) and 3D object creation -- so things like DDS texture formats still create a lot of head scratching.

In photoshop there is a tab beside the layers tab, that allows you to add a shaded alpha channel to a .dds file.
I need to add a black alpha channel to a .dds file.
I've tried every alpha pluggin I can find but cannot replicate this effect.
And if I open a .dds file created in photoshop with a black alpha channel it is completely invisible in paint.net.
Why is it completely invisible in paint.net but not in photoshop?
How can I add a black alpha channel to a .dds file in paint.net?

In order to retain a wider gamut, I'd like to export a .raw file as a multichannel image (psd or any other file type to be opened in photoshop). Those channels should be e.g. c, m, y, k and two spot colours. As far as I understand, this can't be done from within photoshop, since an image presently in rgb can only be converted to a cmy mulitchannel image.
Would you achieve this by exporting the .raw from lightroom setting a colour space (under file settings) that contains such six print colours? And if yes, how ywould I produce such a colour space (that, if I understand correctly, must be present as a file itself, to be selected instead of the default choice between sRGB, Adobe RGB (1998), and ProPhoto RGB)? Or if there is another way to obtain such wider gamut image of more than cmyk.

I have created a short (<3 seconds) video comprised of 2 layers. Each layer was filmed as a green screen, and I used Keylight in After Effects CC to create a transparent background. My ultimate objective is to use the clip to create a transition for use in ProShow Producer, as described in the link [URL]..... To do this, I need the main video file, and a second file containing only the alpha channel.
I have used Adobe Media Encoder to output a FLV, and told it to Encode Alpha Channel, as was suggested, but I only get the one file (the main video). How do I get the alpha file?
I am using AE CC.

What is the more usual image mode? I think my files have been 8 bits per channel for many years. I was having a lot of trouble with Photoshop slowing down dramatically on several large files I created, and I noticed I had made them in 16 bit mode. Would this require more RAM?

I have just installed.
Photoshop CS4 Extended as part of the master suite.
I have also CS3 on the same PC.
Now the channel mixer doesn't show the sliders for tint (hue and saturation); the same happens on the B & W adjustment window.
I try to run CS3 (shortcuts or the program itself), CS4 comes up instead.

I've been colouring an image which was black and white, consiting mainly of black lines. I've made a special channel for the lines and coloured it all in the RGBs chanel, and now when I want to save this as an jpg or at all, the lines vanish. The chanel and the original pic is still there but the lines just won't apply to the rest of the art so they coul be seen, only when I click on the visible or not button at the channel. I've tried to merge it but it still only gives me the colours of the pic without the lines..
