Which file to keep
David
What you do with Tiffs and jpegs is going to depend very much on the software you use for processing - with mine I just keep the raws as Tiffs and jpegs can be re-created from the raw files at will but that may not be the same for you. Which software are you using for raw processing?
Rgds,
Rob.

If you were using RAW+, then I keep the camera's JPG too (putting it in a separate "CameraJPG" directory). The camera's JPG is a useful colour reference

Process the RAW in your favourite convertor (e.g. Lightroom).
If you can get the image to 99% then export straight from the converter into JPG. I have presets in LR for 1000 pixel web-ready images, pre sharpened. It makes life really easy for bulk!
If you need to do some serious post-production, then export to PSD or TIFF (16 bit if you really are going to hammer the image), work on the detailed file. Usually I'll keep just the PSD file with all its layers and tweaks. Then, resize and export for web from there.
HTH!

If I want to scan through what I have filed - easy to run through the JPGs and then I can load the RAW/PEF and process that.

RAW and the original JPG. Both have their uses.

for the same reason, I always keep RAW files and export a smaller jpg version ( currently 1600px ) for everything in batch process after editing a shoot in lightroom

• when masking images. JPEG encoding can produce blocky edges when masking images with tools like Topaz Remask.
• when "pushing" an image. Though rarely a problem, I've had posterisation issues when doing more severe PP that was a result of JPEG.
But, for anything that's almost right out of the raw converter, JPEG is perfect, even for large format prints.

I understand the tiff theory but I've never come across a situation where I've needed it, for my clients, be it onine or print, jpeg seems to deliver the goods
You can open up a Tiff time and time again for edits and not endure cumulative degradation from successive lossy compression and decompression. I save all my 35mm neg scans as 16bit TIFFs.

But if I have finished the layer work (or other PS specific stuff) then I'll 'flatten' it and save as a TIFF - most useful if also needing to adjust something in another programme. Ultimately the TIFFs & .psd files will end up in the same category - a 'Master Working' file for archiving.
They are most useful if you want to produce more JPEGs copies in future, say at different sizes or for new specific print sizes, but you've got the advantage of being able to make fresh adjustments without quality loss (such as on the JPEGs like Smeggy was saying above).
So for me, I have a storage system that saves the DNG's immediately, then another folder for 'Master Working' TIFFs / .psd, then collections of max quality JPEGs (for printing) and higher compressed JPEGs for web use (like the forum / facebook etc). I do keep them all for now, and backup using DL DVD discs. In future I may revise this and choose to delete 'Master Working' files maybe from years past, if there's no possibility I'd ever revisit the shots.

Do I
1)Change the Raw into Tiff,do the necessary tweaks then change to jpeg,keep the Tiff file and bin the Raw file
or
2)Do the necessary tweaks to the Raw file,change to Tiff then to jpeg and keep the Tiff file and bin the Raw file
or
3)tweak the Raw file change to jpeg and keep the Raw file.
Hope I have explained this clearly and once again thaks for the help.I was getting a little frustrated with getting poor pics
