Saving LIFF files

You may ask "Why do I need to think about this?"

Openlab’s LIFF format is only supported by current Improvision software products. To use Adobe Photoshop, you have to use a format that Photoshop recognises such as TIFF.

However when you save a TIFF file it will not retain the LUT (Color look up table) as the LUT is only supported in the Openlab’s LIFF format.

Plus you need to save the multi- layered Openlab file as single image TIFF files, because Adobe Photoshop does not support "multi-page" TIFF files.

OK so now that’s off my chest, let me show you the easiest way to do it.

Let's say we want to save this image to open in Adobe Photoshop.

First take a look at the bit depth, it’s a bit tricky to see on this image but if you look in the bottom left corner of the image document you will see the depth.

The above image is 12 bit.

To retain the green look-up table and to be able to easily open this image in Photoshop the depth will need to be changed to millions of colors.

First of all select the image in the Layers Manager, you can see that I have done this above.

Go to the "Image" menu and select "Depth".

In the dialog that appears change the depth to millions of colors and pick the "Change Selected layers option".

You don’t have to select just one, select as many as you need to process.

OK, so now the image looks the same but is different.

This is quite an easy step to miss, had you not changed the depth to millions the colors the LUT would be lost on saving as a TIFF.

Leave the layer selected in the Layers Manager.

Go to the "File" menu and select "Save as Multiple".

Select "TIFF Image" as the format.

Then click on the "Naming" button.

Hey Presto the "Naming Options" dialog appears.

Set the options up as I have shown above.

By selecting "Save selected layers only" Openlab will only process the layers that are selected.

Again you don’t have to select this option, if you want to process the entire LIFF document leave this option unticked.

When you are happy with the settings in the "Naming Options" dialog click on the "OK" button.

Then click "Save" to save the TIFF file. You will then have one or a number of individual TIFFs that you can use in Adobe Photoshop, or another image processing package.
