So I just got Lightroom a few days ago, but haven't used it yet.
I am now wanting to edit a picture for the Granular challenge.

What do I need to know as far as what Lightroom goes with the originals of RAW images? I used to just import to Iphoto, which leaves them intact. Is that the same for Lightroom?
Just want to find out so I don't accidentally get DQed sometime soon for not knowing and suddenly not having an original available.

Yep, lightroom doesn't change the raw file at all and any alterations you make are stored separately and applied on top - you can view the un-edited raw file you're working on at any point simply by hitting the '\' key.

Also if you're looking for camera profiles they're under the develop tab at the bottom of the right hand pane.

Lightroom uses sidecar files for RAW...it doesn't write into the RAW image, so you should be ok.

Don't select any options to convert to DNG--that would not be acceptable as proof (though you can convert and keep the RAW). I don't think DNG is a good idea anyway with Lightroom...then LR does write into the file, and every time you make a metadata change, you'd have to include the whole file in your backup. With the Sidecar files, the metadata files are very small.

Thanks a lot!
I am glad it stays simple

fyi, photoshop handles the raw files the same way, it doesn't edit them. it adds the sidecar files and then if you doing any advanced editing it automatically saves a tif or psd. leaves the original raw untouched.

lightroom will read the same sidecar files and open any changes you made in PS automatically, and vice versa. also if you are in lightroom, and find its not enough, you can right click and hit edit in PS, this will open your current file state in photoshop for some advanced editing and when you save it, it saves a copy, and reimorts that file for you so you are right back to where you left off, again not modifying the original. very nice.

also if you go back in PS and open the edit, you will be able to go back into lightroom and your LR edits will still be there on top of the psd or tif such as crops and you will be able to change them. this is nice for say if you set all your levels, crops and such and you for got to clone out something, when you get back into LR the edits are all nondestructive so they get reapplied to the new psd or tif file.

for basic editing lightroom cant be beat. check out adobes site for video tutorials that really show you the power of LR.
