I am using windows 7. I tested with a Raw (.NEF) picture and face a few issues:
Using Gimp 2.8.6 with UFRaw. Started testing photivo and face this strange behavior.

- when trying to export from Photivo to Gimp, it opens UFraw and throws a message saying "\<filename.tiff Corrupt data near 0x2. It opens the image in UFRAW but all scrambled.

-Save it first to Tiff format , then open it in gimp, same as before. It opens it in ufraw.

Strange is that I open the same tiff file in other editor and it opens fine (like lightzone, or a tiff viewer)

Is it because it is not compatible with UFRaw?

Thanks

But why you want use tif ?
you can export as png , same looseness quality , smaller file size, and larger compatibility

About tiff Gimp has some limitations , let say that are several types of "tif" , different for different kind of compressions, embedded camera's data or not, alpha or not and not all types are supported by gimp .

Tiff supports 16-bit depth. If you have spent some amount of time with the RAW processor it makes sense to keep these results in all their glory, in case you want to process them later with some 16-bit-capable software (some future Gimp version for instance). Some raw processors will save a "recipe" to reproduce the processing on the very same image or on other images shot at the same time but nothing says that their own future versions will produce completely identical results...

For photography, high quality JPEG (Q>=95) is just as good as PNG.

yes and PNG too support 16bit !

Yes but few apps can produce these 16-bit PNGs.

Well it seems you've already done what I was going to suggest and posted your problem on the Photivo Flickr forum: http://www.flickr.com/groups/photivo/di ... 902773029/

I assume you tried searching that forum and that this thread didn't help: http://www.flickr.com/groups/photivo/di ... 712902398/

Re-reading your post, you are saying the when you go to GIMP and try to open a .tif file, GIMP is using Ufraw to pre-process the file? That doesn't sound right as GIMP is capable of loading .tif without needing Ufraw.

That said, GIMP doesn't read the EXIF data from .tif files so you are probably better doing what Ofnuts said and using a .jpg as the transfer format. (Which is what I do)

Don't know,i never had problems with 16bit png
luckily all the apps i use from Photivo to Rawtherapee ,and including viewers as Xnview may load, edit & save 16-bit PNGs

I would see in a modern graphic tool supporting 16 bit the luck of support for 16bit png if not a critical bug at least a severely missed function

Instead i read several times complains regarding various graphic tools for insufficient or buggy support for some type of Tif

and again png is looseness as tif but offers a smaller file size
