PANASONIC FZ20 Uncompressed TIFF images

by Scuppun1 / November 9, 2006 7:18 AM PST

When I download images I have taken in TIFF (uncompressed) format, I get a picture that has the right hand quarter of the image removed and pasted on the left hand side of the image and the colour phase is out. I know this is how uncompressed images are saved, but the problem is, how do I correct them in Photoshop or some other product. Does it only correct itself when the images are printed? Can any photo store correct them? Please help.

I don't know what you are looking at, but Photoshop displays
by Kiddpeat / November 9, 2006 7:56 AM PST

images in EXACTLY the same way as they are printed. It does not show the image broken up into some sort of segmenting scheme.

How do you know how uncompressed images are saved?

Perhaps you should start over again, and describe in more detail what you are doing, what software you are using, and the type of computer you are using.

Uncompressed Images TIFF
by Scuppun1 / November 9, 2006 2:11 PM PST


The computer is not the problem.

The image I download from the camera (just simple downloading of files, no extra tricks - drag and drop to a folder on the desk top), then viewed in either photoshop or XP fax viewer is as follows.

Example: 4 x 6" landscape picture) The right hand side of the captured image appears to have been cut and added to the left hand side of the image. The CMYK colour phase has also been shifted. I know this is the uncompressed image because I have asked Panasonic about this. They, for some reason or another, won't tell me how to rectify the image using photoshop ("not their problem").

I am using Adobe Photoshop CS. There shouldn't be any issues with manipulating the image. A lower resolution JPEG image is also captured at the same time a TIFF image is captured. This image is perfect, but not the TIFF.

When you look at the files stored on the camera when it is connected to the computer still shows the same problem (before you download anything). It's not the equipment, it's not the software, it's a matter of converting the uncompressed image.

I used to download tifs from a Nikon in exactly the way you

describe. They never looked like anything except a normal photo either in the camera, or on the computer.

Does Panasonic supply software with the camera? You might need it to convert the image to a standard format. You can tell it is not in a standard format because Photoshop does not display it as a normal photo. The problem is in the camera, and, apparently, the way Panasonic stores the image. Only Panasonic can fix it.

Do you have the option of turning the jpeg image off so that your camera records ONLY the tif image? If so, turn the jpeg off. Then see if the camera itself can correctly display the tif through its LCD. If it does, try the download again, and see if the rest of the world can correctly view the image.

Panasonic is giving you a load of BS. That's not unusual. It's their problem, and they need to fix it. They are supposed to supply images using industry accepted formats.

PS: Windows Explorer should also be able to view the photos

if you set the viewing option to either thumbnail or filmstrip.

Found the problem
by Scuppun1 / November 12, 2006 12:29 PM PST

The problem was a low quality 2GB SD chip. The data could not be correctly stored on the chip. I used other higher quality name brand SD cards and I had no problems with the TIFF images. Problem is now fixed. I just have to get a better quality 2GB SD card.

Says a lot for "customer support". Great camera, bad customer service.

That's interesting

I didn't know that the FZ20 could handle a 2GB SD card. Don't forget to format the card with your camera. This can prevent problems like that. Panasonic has a support club that you can join. They are more usefull than their Tech support.

Could you please provide me with the web address (if any) of this Panasonic Tech Support Group. I would like to see if a better quality 2GB SD card still has the same problem, however if the better quality cards are OK, then there should be no issue.

I guess it's a matter of "Watch this space".

how to fix fz20 tiffs from 2 gigabyte cards
by tnoll1 / June 9, 2009 7:11 AM PDT

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 ''.

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 "" 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 (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 ./ $tiffimage; done (does the conversion!)

Step #9 is where the work begins. What it does is run the 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
