I've been taking pics in the fine jpg mode all along with a 2gig chip (Sandisk Ultra II) with no file management problems. But this weekend I decided to shoot a few pics in TIFF mode and none of them turned out normal. That is, the color was not right AND part of the pic from the right side was cut off and appended to the left side of the shot. When opening the pic from any program there is a message 'unknown field with tag {blah,blah,blah}.....' before the pic loads.

Works normally with the 1gig chip.

Anyone else find this problem and is there a way around it. I know the manual only lists a 1gig chip for use. The file sizes for the TIFF image are obviously much larger and I'm thinking that the size crosses some file system boundary/limit and mangles some of the data.

Just trying to confirm my suspicions.

A 2 gb card will not record TIFFs in the FZ20.....not sure why, but it is a fact.

But There is little if any advantage to using tiff.....I really believe there is no benefit....but someone will tell you there is.

Thanks, I have no problems with jpeg. Just happened to be playing with the camera, shot some tiffs and was concerned about the mangling, until I found the 1 gig chip worked OK.

Thought there was an abnormal problem with the camera.

Have you seen this thread on DPReview:


It not only answers your question, it links you to a method to recover any garbled TIFFs you may have already taken.

Personally, I'd stay away from TIFF in the first place. I take all my FZ20 photos in high quality JPG. When I upload them to my computer I save them in a folder that is never ever edited (they are my original negatives). Any edits are done with Photoshop Elements and saved in a separate, parallel folder in PSD format (for further editing) and a copy in JPG format for sharing (mostly on my SmugMug site).

There is a script out there that is written for the Macs which supposedly will also recover full TIFF files. Although I initially ignored but then posted the url for theUNIX and Windows scripts, I have yet to findthe Apple script which I also saw earlier.... But it's out there for those who want to search for it. For a guy who doesn't use a FZ20, a 2GB card, or a Mac...I've done enough.:lol:

Default how to fix FZ20 tiffs from 2 gig cards

I just encountered the same problem with tiffs and a kind friend wrote me a Mac terminal script to fix it since I couldn't run Windows' Irfanview and do 'swap colors rgb to brg.' That still left the slices to move anyway.

I also emailed Lemke Graphic Converter and he put the fix in version 6.4.2. Open the program, go to file/convert and modify, navigate to the image in the left window, choose function/fix Lumix FZ20 2 gigabyte tifs in the dropdown and click go. I imagine if you select all the images and click go it will batch them.

Here's the terminal script. It needs to be put in a plain text document named 'fixtiff.sh'.

for FILE in "$@"
echo "Fixing file $FILE"
dd if=$FILE of=1 bs=16384 count=1
dd if=$FILE of=2 bs=16384 skip=2
cat 1 2 > temp/$FILE
rm 1 2

Then follow these instructions:

1. Make a NEW folder called "PhotosFix" or something friendly on your Desktop. If you name it something different, be sure and use the new name in each step below.

2. Put the "fixtiff.sh" file into the "PhotosFix" folder above.

3. COPY (copy, not move!) all your photos into the "PhotosFix" folder as well

4. Open Terminal. After each command below, hit enter. I've added space to make it clear which part is the UNIX command.

5. Type cd ~/Desktop/PhotosFix (changes to your home folder)

6. Type mkdir ~/Desktop/PhotosFix/temp (makes a TEMP folder - where the fixed files will be)

7. Type chmod +x fixtiff.sh (makes the script "run-able")

8. Type ls *.TIF > list.txt (makes a list of all your TIF files in list.txt)

On my computer I needed to do an 8b. Type bash (had a different shell than the creator)

9. Type for tiffimage in $(<./list.txt); do ./fixtiff.sh $tiffimage; done (does the conversion!)

Step #9 is where the work begins. What it does is run the fixtiff.sh script on every file in the list.txt list that is made in Step 8. The script itself takes the first part of the file, skips the 16k of garbage, and then adds the rest of the file.

Some important notes:

1. There cannot be ANY spaces in the file names. None at all!

2. Files MUST have a .TIF extension on them. (the ones you sent both did)

3. All the "fixed" images will be in your /Desktop/PhotosFix/temp folder

Tiff as far as shooting in tiff is not an advantage. Tiff as a final file for print is an advantage as it is lossless.
