NX-D problem with Tiff conversion

[FONT=&quot]New to using NX-D to modify and convert images from RAW to Tiff on imac. When converted images are opened in preview each tiff file has two images. the top one is normal and number 2 is tiny. When the tiff file is opened in GIMP the image has a second image embedded in the upper left corner. the small image is actually on a separate layer. I then have to drag the second layer to the trash. Very tedious. What do I do to eliminate this second image. Any suggests would be most appreciated. Thanks[/FONT]

TIF/TIFF is a Lossless format. The file spec allows for compressed images to be packaged in the TIF... Software vendors frequently do that and use the compressed image for screen display rather than trying to load and render the entire uncompressed TIF file.

Thanks Fred for the info. Does the large or number1 image contain all the information or is it split between the two images? Is there a way from only the one image to appear.

Well... I'll take a run around NX-D and see... I don't use NX-D because there are so many other better options... and I don't generally have the issue you're having on my Mac with Preview...In fact, I generally export images to TIF files from Adobe's Lightroom and use Preview to open and print them to a Canon photo printer... Hang loose... it make take a while. It took 3 minutes for this slow forum to even resolve a screen...

Okay... I downloaded and Installed NX-D... and converted an image to TIF

It indeed embeds a small thumbnail image in the TIF file.

You can control whether you "see" the thumbnail by turning it OFF in the Preview menus, and you can display the base image only by also turning OFF the Sidebar in the Preview menus...

Interestingly... I played with Preview a bit while there researching this... and Preview is a pretty fair editor... almost as much as Camera Raw...

Fred, Sorry for the delay in getting back to you..been out of town for a while. Thanks for the help and the suggestions on removing the thumbnail. Much appreciated!

Another thing you must remember is that you can save to TIFF either in 8 bit or 16 bit image. If you want to utilise the full dynamic range of the image in any downstream application, then you should save it in 16 bit format.

Regarding the embedded low resolution image, that is just a thumbnail and most software will ignore it while processing the image. No need to throw it away.
