Photoshop: Using Tif Plant Files To Render Perspective Views

So here is the deal I have a few jpeg perspectives that have been rendered in revit but I need to add trees. I have been given plant tif files that have already been cut out (the outline and the empty spaces between the foliage) and when I place them in a program like sketchup they work perfectly by allowing just the tree to show up and be able to see through the empty spaces in the foliage, but when I open it in photoshop to try and add it to my perspective jpegs the background and empty spaces fills with black, which means I would have to go back and cut everything out, which would take forever. So is there a way to open the file so their is no background so it is cut out and has visibility through the spaces?

Thanks

Do the plant TIFF images open up with transparency in Photoshop?
If not, they're probably written incorrectly.

Preview and Apple's file reader gets transparency wrong in TIFF and a few other formats (we've filed bugs, and they're working on it).

Photoshop gets it right (have to, since I maintain the TIFF spec.), and those files are simply written incorrectly. If you really want, you could mail me a file and I'll tell you exactly how incorrectly it is written. But the bottom line is that you need to contact the makers of the app that wrote them and file a bug about their TIFF writing.

o ok that makes sense, thanks, now my next question is that all the background is black so is there a way to select the color black in the entire project and delete it even though the patches of black are not necessarily connected?

yes, using select -> color range OR check and see if there is an alpha channel that could be loaded as a selection (there probably is, they most likely mislabelled the transparency channel and it's there as an alpha).

ok il be completely honest I am not very tech savy so I have no clue what the alpha channel is or how to load it, and when I use color range it ends up selecting the majority of the image even though it isn't black so I am not sure if I am doing it wrong or what. Thanks

In color range, you have to define which color and what range you are selecting. And for alpha channels: look in the channels palette.

Chris F: use the magic wand, make sure that "contiguous" is unchecked in the option bar, and select a black area. You might need to adjust the tolerance.
