Back to the OP, Save all of your raw files, ALWAYS. You can also save you edited works as PSD, so if you feel the need to go back and make other edits you don't have to start from square one with the raws. For you final output to give to your brother or print, I would use quality 12 jpegs.
+1.
To everyone... including the OP...
RAW files are essentially negatives, or as close to them as you are going to get with a digital camera. This means that you have
all the data that the camera saw at the time of capture, and always have the option to go back and re-interpret that data later on.
With any kind of lossy compression format (such as JPG), you are losing data when you save it, thus reducing your ability to make exacting modifications later. The data is quite literally gone. This is not completely different from making a print from a film negative and tossing the negative when you are done.
Disk space is ridiculously cheap. Never ever
ever EVER throw away your RAW files.
Not ever.
BTW, I understand JPEG2000 has the option to be lossless, but from what I read it also doesn't store EXIF information. That kinda sucks. Tiff is better overall, but still... don't toss the RAWs. Never toss the raws. Repeat after me. "I will never toss my RAWs."
If you're shooting medium and large format film like you do and are going to be making mural sized fine art prints NOT on the Noritsu at the local Costco that you'd like to be able to put your nose into and still see fine detail then by all means use TIFF. It'd be crazy not to. Little DSLRs with their crappy Bayer interpolated sensors are not even remotely in the same league and have a lot more things limiting them than TIFF vs JPEG for printing, which is why I think this is all silly for DSLRs and completely out of context.
Take a sample image and get test prints done on whatever printer you're going to use from both a TIFF and a JPEG and see which one looks better, or if you can even tell? That's what I'd do. And I really don't think there's much point in passing along the RAW file to the couple. Chances are they'll have no clue what to even do with it, probably won't even be able to open it, and if they want to tweak stuff there's still plenty of leeway to tweak on the JPEGs themselves.
This is kinda like the whole 128bit argument with MP3s. "I can't tell, so therefore it's fine!" Most people claim they can't hear the difference, but I have years and years of experience in music and have a very trained ear, and I have some fairly high-end equipment that rather significantly amplifies any flaws in a recording (as well as anything GOOD in a recording), so
I can tell.
So be it. I listen to 160s on the "cheap side" and 192s and higher for anything I care about... you can listen to your crappy 128s, but I scream bloody murder when I hear a 128. Fine. There are people who would have me drawn and quartered for listening to 192s. There are people who would have THEM drawn and quartered for listening to MP3s at all. There are people who would have THEM drawn and quartered for listening to anything other than Vinyl.
Can they tell the difference, really? I can't say. I know for a fact I can with great accuracy tell a 128 vs. anything higher, but I can't often tell if something is above a 160, and I can never tell if it's above a 192. Doesn't mean that it isn't better, necessarily... it may actually just mean that
I lack the equipment to tell the difference.
You print your JPEGs if that makes you happy... I can often tell the difference, so I'll print TIFFs, thanks. You say tomato, I say tomato.
HOWEVER...
If I was ripping a CD for
someone else, I would do it at no less than 160. If I were printing an image for
someone else, I would certainly use a TIFF. Why? Because I may well know what's fine for me, but I can't say for sure what's going to be fine for them... and, again, going back to the lossy vs. lossless thing, it's
safer to give the printer more data to work with than less, regardless of whether the software happens to be too braindead to benefit from the extra information.
More data is better!
Oh yeah, and keep you RAWs. Did I mention that? :lmao:
