No, Photoshop does no such thing.

Photoshop only puts channels into TIFF channels.

Photoshop can save layer data in TIFF files - as a custom data blob. The layer data written into that blob matches the layer data representation in PSD and PDF. And the Photoshop SDK documents the contents of that data.

Hello Mitesh,

Wednesday, December 17, 2008, 1:34:24 PM, you wrote:

Our tiff files are created in Photoshop composing of several layers (50 +) and then saved in a tiff file.

Now I have to write code to separate each layer information embedded in the tiff file and GENERATE A SEPARATE FILE for each layer. Or in other words decompose the combined layers

There is a confusion about multipage, layers and channels.

Can somebody explain in detail what are the above?

Do you all mean to say in Tiff layer data is stored as channels?

When you export a TIFF file, Photoshop puts each layer into a separate TIFF channel. (It also writes a custom TIFF tag with some information about those layers.) So, if you split the TIFF into separate channels, you should get what you need.
