You might not need it. I started using Lightroom a few years ago for two reasons: it makes non-destructive changes to the original photo file and I like the way it catalogs my files. I shoot mostly raw, after I process the raw file to the way I want it there is no need to make a copy for jpeg or tiff until I need it. The original raw file is still available. If more PP is needed I take the file into Photoshop and finish it there and save it as a jpeg psp file.
Up to getting my K-5 II I was a Canon guy and had lightroom change all my files out of the camera directly into the dng format. Now with the Pentax I just save it as a dng in camera.
Another reason I was able to get into lightroom & Photoshop was my wife is attending college and I was able to purchase it with the student discount.
