Start by plugging your digital SLR camera into your computer and then copying the RAW photos onto your desktop or another storage area on your computer. Open up Photoshop and go to Edit and select Color Settings. You may want to change the RGB to Adobe RG 1998 and then make sure that the Profile Mismatches "Ask When Opening" box is checked.
Go ahead and open Adobe Bridge and then select the images from your desktop or selected storage area. You can also use Adobe Bridge to view the available META data of the images. Since you have shot your images in a RAW format you can select them and a detailed menu will come up allowing you to choose a series of options. These will include changes to your brightness, contrast, exposure, saturation, white balance, clarity, vibrance, and other features.
Here you can make a few changes to your image before you enter into Photoshop, but you must remember that these are destructive changes and will fully change your image. You may want to address some of the blacks, fill light, and white balance, but do not do too much to the image in Bridge as you will be doing your real work once you get into Photoshop. Once you are finished making changes, which can go as far as changing the available pixels per inch, you will hit the Done button in the lower right hand corner. You can also save the RAW picture to an entirely different format, such as a compressed one, you can hit Save Image in the lower left hand corner. If you want to actually import the photo into Photoshop, which is the workflow you are doing, then you will hit Open Image. This will send the picture that you altered in Bridge over to Photoshop, and you will start your real editing.
