Okay, we have talked about TIFF images; we have talked about JPEG images, but let us take just a minute and explore what the PSD file extension is. I am sure you have seen that from time to time. What PSD is, is the native Photoshop file extension that you will use whenever you want to close a project out and then go back to it later. PSD has no compression algorithm whatsoever, it is a lossless type of imaging format, if you can call it that. It is not even really a format; it is simply the native file extension given by Photoshop when you want to save all of your layering information, all your history information and come back to the project later. So here I have got a photograph of Division One basketball referee Milt Stowe giving instructions to some high school referees at a basketball officiating camp that I went to about two years ago. So I just put this picture in here and gave it some arbitrary layers just to show to you, just to demonstrate to you what happens. Now if this were a TIFF image and you were to close it out, you would lose all of the layering that you presently have. If you brought the image back up, it would just go back as a background and then the initial layer would be there, but as a PSD, it comes back exactly the way you left it. Let us take a look; we are going to shut out the image, notice this when you close the image, all the layering collapses and you go back to something else. So we open that file again, make sure that when you are going to open the file as a PSD file, you do not have the TIFF image extension showing at the bottom here, look at all these choices you have. But the PSD file is what you want. Here is 07; open this again and you can see how all the layers come back into view when you reopen that image. Be very careful, if you collapse this out as a TIFF image you are going to lose all your layering information. So be sure that when you do it, you go file - save as, and make sure that this is designated as a PSD file when you save it. The other thing to keep into consideration is that PSD files are much larger than the corresponding TIFF image. That is because when you do have the layers, you have three layers with the same amount of color information that you would on just the background layers. You've got three four times the color information than you would on a normal TIFF image. So just be ready for the fact that the PSD file is going to be huge, we can always collapse it down, you can always convert it into a TIFF image later, which will bring it back down to a normal file size. But while you are working on it be sure to allocate the proper amount of space on your hard drive for the storage.
