Hi
After editing in photoshop one is faced with options when exporting your photo to amongst others
jpeg or Tiff.im led to believe Tiff contains more information but is this noticeable with the eyes and apart from size
what would be the objections to outputting Tiffs as opposed to the usual Jpegs?

thanks
 
With the jpegs you will loose some date as far as I know.
With the tiff you don't loose anything.
But then what is your aim when exporting the photo.
If you use it for web then jpeg is good but if you need to work on it again you should save it as tiff because every time you work on a jpeg file you discard some data.
Not a very elegant explanation maybe but trying to help as much as I can.
I am sure there will be others with more knowledge coming here soon to explain better.
 
Thanks Sag.
No the idea is its after final editing to display on my mac,thats what makes me think probably Jpeg is enough but if Tiff does actually look any better i would not be bothered re the size of the file and just save as Tiff.
what do you think?:)
 
I think you will be OK with jpegs.
That is what I do once the editing has been finished.
I then back up my raw files somewhere else for future use if I ever need to go back to them.
 
Where you saved them. Lightroom doesn't move the files themselves, just catalogs them.
Once you edit and export them you can safely move them around to other storage devices if you are running out of space on your hard disk.
That is what I do, otherwise the storage in my computer fills up quickly.
 
As long as you have finished editing them maybe do what i do. Save 1 version as a PSD complete with any adjustment layers added and then flatten the image and save a JPEG copy. That way you can do any minor adjustments after if needed and not lose any detail x. They taught us that at uni this year x
 
I was led to believe that every time you opened and closed a jpeg in PS a small amount of the information was lost. This does not happen with Tiff files so it is better to save the files as Tiff images for editing and only convert to jpeg when necessary, ie. for saving to a web page etc.

That only happens if you open the image in photoshop (or similar)and make any change, then the image is saved and compressed again. That said I've seen tests where an image has been opened minor ajustment made and saved 20 times and the difference is minimal, not really noticable with the naked eye. Obviously it's good practice to not resave images a lot but for most of us it's only going to be once or twice anyway so I wouldn't worry.
 
Of course we can use the raw file again and start from scratch cant we.
Which brings this up.when say putting the sd card from camera into the reader would it be best to save all to a folder on either hard drive or ext drive,and then import because are adobe Dng files altered raw files or just their way of storing the raw ?
Aplle photos always keeps the raw file seperate so you can export either modified or original and it gives option to work on either at anytime also.
One other question,after editing in PS how do i send the photo back to lightroom?
Cheers
 
Personally I always keep the camera raw files, I download the card onto the computer, back up at least twice (and dvd) then edit, I don't use DNG, IMHO the lack of support for DNG makes the original camera raw a better option, (theres also been talk of a new version of DNG and it still isn't able to hold all the data from some camera makes) Thats a personal choice for me, it isn't everybodies choice.
Are you opening the images in photoshop from lightroom or just opening them in photoshop first?
 
Hi Wayne,i open in LR first.
So just to be clear is there an option to not convert them to dng.do they then stay as say nef for nikon and cr2for canon.i find it all very confusing.
If i understand you,you 1st save the raws before going into LR and dont convert to dng,? Also i did a little editing in PS saved file as jpeg in a folder on hd and the colour looks washed out compared to the one in PS i saved.
I have to admit im beginning to wish i hadnt gone for the CC Lr/PS package and just used Photos app,its a lot less headache lol
Cheers
