Flattened tiff Problem

[KTG]

I am having a puzzling problem with a flattened tiff.

I am on an iMac with PS CS6

I have a normal layered file. 16 bit. I flatten it. Go to Saved As and save as a 16 bit tiff. I get a normal thumbnail image.

I then import it into YouSendIt to send to a photographer. In YouSenIt there is a preview window When I select the Tiff file from the desk top the preview window only shows one of the layers; not the whole image. It showed the sky where I had selected the sky and put in a new blue sky. I am targeting the top
layer in the stack when I flatten.

I sent myself via YouSendIt the flattened tiff and I did get only the sky selection.

I tested other 16 bit images and they were fine. Nice image in the YouSendIt preview window and successfully sent.

I can flatten and make jpegs just fine also.

Corrupted file or am I doing something wrong? This has not happened to me before.

Any help is appreciated.

Do you have backwards compatibility for layered TIFFs on? Also, it is very likely that YouSendIt can’t preview a layered TIFF properly but the TIFF and layers are fine. Not all products that support TIFF fully support the latest versions as spec’d by Adobe.

Andrew thank you for your response. I have tested the file by sending it to myself and it does show the single layer of the masked sky and not the full image. I also have sent other 16 bit tiffs through YSI with no problems. "Backwards compatibility"? I'm not sure what that is and where to find it.

Your best bet is to zip the TIFF and try sending it to yourself. Unzip, check the layers. It is always a good idea to Zip such files for transmission, not only for size but to honor the data.

Thanks!

sounds like you might also have an alpha channel left over. Alpha channels in the file can change the generated preview.

Thanks for that insight. I'll look at that. I'll bet you're right.
