Rendering with no background

Hi All,

I've created some renderings as tif files with no background, and the Alpha channel enabled. If I open them up in GIMP (my free photo editing program) they look fine with the grey and white checkered background indicating that there is in fact, no background.

Now my client opens up the file in Photoshop and says there is a black background. Is there some setting he has which is filling in the background? Maybe some Alpha channel setting?

Any thoughts would be greatly appreciated.

Cheers

Thanks Dan,

The clients out of the office for a few hours but I'll check when he gets back.

Looks fine in Photoshop. Perhaps they have a setting that shows a default color for clear alpha channels?

Here's what I see in Photoshop (see download).

Thanks for all the help people. Now the next question is, what format should I be using to render with no background if my client has an old version of PS?

I'm doing test renderings right now to give to him but any tips would be great.

Cheers

Can I give you his email so you can tell him that? Just kidding. I still have to invoice him.

As to the format I'm already sending him tifs. I'll try PNG. I've tried Photoshop files but Solidworks always freezes after it's 3/4 finished rendering.

PNG is supposedly a "lossless" format, meaning excellent quality in a much smaller file size than TIFF. So that's what I've switched to using instead of TIFF, and it works great.

He says he's using PS2.

Has anybody heard of this problem in that version?

Thanks.

I thought PS2 was a gaming console, not an image editor. [wink]

What does he see in a standard image viewer (like Windows Photo Viewer)? Should be transparent in that as well. I'm using only Photoshop Elements (v8.0 or so), and that works just fine for everything except color separations (for printing), but without the price tag. Perhaps he could "upgrade" to that for less than $100? The problem is not the image.
