I have almost always used the raw conversion software that came with the cameras, but recently, wanting more advanced lens corrections and other enhanced tools and flexibilities, I decided to try Lightroom. Unfortunately, it seems difficult to work with, although that may be due to my ignorance, which I hope you can cure. First, I absolutely do not want Lightroom interjecting itself as an organizer of my images. I want to (1) open a (typically raw, but sometimes TIFF or JPEG) file for working on, by using a fairly normal Open-type dialog box; (2) when I'm done, I want to use a fairly normal Save As dialog box to choose a name, location, and file type for my edited work; and (3) close the file and have Lightroom forget it exists. However, Lightroom seems to insist that I add images to its catalog before I can work on them, and the export process is painfully cumbersome if I want to, e.g., create two or three different versions with differing names that mean something to me. Second, Lightroom appears to refuse to apply a lens profile to a TIFF. I ought to be able to apply any lens profile on my system to any file I want. But when, for example, I tried to apply the Sony DT 16-50mm f/2.8 SSM lens profile (which applies just fine to the raw files) to a TIFF I created in Sony's Image Data Converter, the profile is not available. With so many of you seemingly so happy with Lightroom, I figure it must be me. But so far, I've found it an officious nuisance. Please tell me why I'm wrong / how to make it behave. Thanks!
