Lightroom :: How To Export RAW File As Multi-channel Image
Aug 3, 2012
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.

As 3dsmax is used in so many different areas, I try to get an overview of the use of multi-channel OpenEXR files. EXR files are usually used as an intermediate file format to hand over cg footage to compositing for further processing. Different compositing packages are handling EXR's more or less comfortable. My guess would be and that is not meant as a judgment if you comp in afx, it is less likely that you use EXR files, but when you comp with nuke, I am pretty sure you do. With composite and fusion somewhere inbetween. Also, when you work in ArchViz and MoGraph you propeably prefer psd files, while when you do tv commercials and film works, you are more likly to use EXR.
The questions in the poll are meant in a general way. It doesn't mean when you vote 'Yes' that you exlusivly render to EXR.

For a long time I have been struggling to find a good workflow for what I would call "multi channel color separation". What I want is to reduce a full color RGB image into an image with only a limited number (e.g. 5-8) well-chosen colors, for instance to use as set of masks for screen print. (I'd also like to use this as an effect in itself, mimicking a typical 'screen print' or 'litho' effect on an inkjet print)
The idea is to create a set of monochrome layers or spot color channels. Colors are to be selected by myself (so not necessarily RGB or CMYK). Each channel/layer has to be a continuous tone that I transform myself into a dedicated half tone screen (e.g. with the Andromeda screen filter).
Till sofar it is clear to me. My issue is: How to separate the image in the predefined set of colors?
I can not just select a color range: I can adjust a "tolerance" but that is too general. I need the pixels of with a specific hue but with the full range of lightness (e.g. all the purple pixels that range from dark/medium purple to very light purple). The dark colors can be made dark with a black channel. I'm not sure how to deal with the saturation range.
An approach that gives sometimes a result that is to some extent acceptable is to transfer from RGB mode to an Indexed Color mode and use a custom palette. However, this does not give much control on the halftone screening process.
I envision for instance an approach of filling a layer with a solid given color, select in one way or another only those parts that correspond to the original image and subtract that layer somehow from the image. This process is then to be repeated for each color. Up till now I have not been able to figure the right options to do this. But maybe there is a better way to do it.
One final wish: it would be great if the process can take into account that some layers in the final print are (semi-)transparent. In my opinion this would exclude just selecting a color and deleting de pixels.

I'm working in the multi-channel format, which as you may know, does not support layers.
Does anyone have any tips on experimenting with the layout, without the use of layers?
At the moment, I've been working out the layout in another (layer-supporting) colour mode, and then recreating that layout in the multi-channl mode.
Surely there is a better way of testing different layouts, within the multi-channel mode itself? I'm finding it very inflexible at the moment.

According to the Help for Lightroom V1.0, I can choose to print my identity plate on each image on the page:
>To have the identity plate appear on every photo in a multiphoto template, select Render On Every Image. The identity plate is centered on each photo and can be moved, scaled, or rotated using the controls in the Overlays panel.
I can move the ID if it is rendered only on one image.
I cannot figure out how to move the ID plate once I have clicked "render on every image." It seems to be fixed in the center of each image.

I've got a dodgy Google Earth screenshot that I've chucked into CAD to scale it (approximately) and more importantly align it to the correct coordinate system as per the survey. However, I need to use that image in another modelling program (which only accepts image files).
Question is - is it possible to export just an image from Autocad back to an image file? I obviously don't want to plot the entire drawing to PDF/BMP or anything, simply extract the image that I have resized. Or any other way of getting an image from Google Maps or the like and scaling it correctly?

I am using X4 and am familiar with chroma keying and setting backgrounds but I am trying to export the video with the alpha channel so I can create a flash file with transparency to use for walk on video (where the person appears in the foreground of the site with wmode set to transparent).
I have Corel Motion 3D and some of the kbase was suggesting I needed to use that to export with the alpha channel but it would be a lot simpler to be able to push it out from X4. Even if I can do it as non-flash file I can take it to something like Ijoysoft and convert to flash.

I have created a logo using Illustrator CS5 and need to import it into a video sequence in Final Cut Pro 6. The logo has a transparent background. It seems FCP 6 will import both native .ai files as well as .tiff files, but when I open them in FCP 6, the alpha channel (transparent background) is no longer there; there is just the logo over a white background.

I have created an image on illusrator CS6 and am ready to save it.
I have saved it as a pdf format and the image stays as a sharp vector image and not blurry at all.
But I also want to keep the image as a jpeg. So when I go to export the image from illustrator CS6 as a jpeg, the end result comes out blurry and not sharp anymore, but more jagged on the edges of the image.
Is there anything I can do to keep my file as a jpeg with it staying as a sharp crisp image?

I have collected 30000 photos from a WebCam and I would like to make a time lapse. Pictures are taken every 15 Minutes and they are in sequence order (00001...00002...etc). I actually dont need them all for the time lapse and would like to export only lets say every third or every fourth picture. How can I do this with Lightroom?

I created a sketch that I would like to use in an iFeature. The sketch dimensions are controlled with an ilogic rule referencing a multi value text user parameter, eg the text parameter pull down menu controls the size of the part.
Is there an easy way to get this parameter into an ifeature or derived part?

I've created an image file in Illustrator and exported it as a .png file. The dimensions are 1000x200 but when I export it the file size changes and becomes bigger. I therefore have to change the file size in Fireworks making sure that the quality is kept as Photoshop does not do it for me. Previously when I exported the files the backgrounds appeared transparent after saving but maybe I've changed a setting by accident that has changed this. I'm selecting the 'Save as' and Flattened png option at 32bit in FW.

When I export my raw or dng file to jpg, the jpg thumbnail (in a standard windows viewer) looks strange, color is pinkish and washed out. However, the full size image looks fine. On the reverse, normal jpgs sent to me or right out of the camera look fine but the full size image in the same standard windows viewer look dark and very contrasty.

Lightroom 4.1 will not export a deleloped image. I have the metadata to new file set to automatic and I get no error mesage. All my new exported files are the same as the original. I need a detailed discription of what boxes need to be checked or unchecked and where to find them. Something as simple as saving changes so that I might use them in another app should not be so difficult- version 2.7 worked fine so what's up with 4.1?

I am having trouble exporting my RAW files as JPEG files. At first Lightroom 4.4 seemed to skip certain photos when exporting and now I'm unable to export more than one image at the time. How can I fix this? I didn't seem to have this problem before the 4.4 update, but then again, the 4.4 update has been running for a few days now. I run on a 32bit Windows 7 with 4GB of RAM.
Lightroom has also been a considerable lot slower since the last couple of days, yet there have been no changes at all to my computer or system or anything - nothing's changed expect for the fact that Lightroom isn't behaving as it used to.

In short, I have two images open in Gimp. I need to add one the images to the alpha channel of the other image. How do I go about doing this? I was able to add an alpha channel but beyond that I am lost.
This bit will only make sense to 3D modelers. I have 3D model that I'm importing into a the Unity 3D game engine. One of the material shaders makes use of specularity maps. Normally the specularity map would reside in the alpha channel of the RGBA diffuse image, but due to file sizes, all these are released as separate jpegs. The idea is to make some parts of the 3D model more glossy as far as I know. The only way to do this is to add this specular image to the alpha channel of the diffuse image, and then the game engine can work its magic, making the skin look realistic.

When I export a photo to a sRGB file, there is way to much color in the photo. In Lightroom 4.2 the photo looks good, but when I open the exported photo It looks like its to much saturated. When I export the photo as AdobeRGB (1998), strange enough the photo looks for 95% oke.
I'm using a Eizo ColorEdge CG243W monitor in sRGB mode. To ensure that it's not my monitor that's causing the problem, I've watched both photo's (sRGB and aRGB) on a standard monitor on a different computer. The result is the same: to much color in the sRGB file, pretty good colors in the aRGB file.
I'm using Windows 7 Home Premium, 64 bit. My videocard is a MSi Radeon R7850. I'm using Lightroom 4.2 (system info says: [850741]).
I've just bought this system. Before I've used another computer, with the same monitor, were I've tried Lightroom 3.2. I didn't experienced any problems there. Then I also used the monitor in sRGB mode. When I exported to a sRGB file, the photo came out perfect.
