Well, I have to save my modified files in an original format (.NEF) and save them on in my Mac desk.
You can either save the original files as (.NEF) or the modified files in another format to the Desktop. But you cannot export your modified files as NEF.
The raw format generated by the camera is the raw sensor format. Aperture will store this original image file for you, and you can export it again. To view and adjust the image it has to be developed to create an image file. The developed and adjusted image versions will not be exported as raw files but in an image file format: jpeg, tiff, psd, png, ..., but not as .NEF.
Thank you sir,
But I'm not sure I can't export the modified file in the original format.
Until recently, I save the modified Raw file in desk and I open it with Camera Raw and Photoshop.
I need to save the file in .NEF. (if I use Canon, .CR2). As I said before, I consider useful the possibility to create libraries with all your photos but if I can't export the modified photo...
You're confusing the Raw data from the camera sensor with the photo. They are not the same thing.
When you shoot in any camera the sensor data is interpreted and processed into an image file. So a point and shoot will output a Jpeg.
Higher end cameras allow you to do that interpretation and processing for yourself. It saves all the sensor data as a Raw file. But that is not your Photo. Your photo is that data interpreted by the 'digital darkroom'. That interpretation can only be expressed in an image format - jpeg, tiff, png or whatever.
So, a "modified Raw" is a contradiction in terms. If it's modified then it's no longer Raw, if it's Raw, by definition, it has never been modified.
So, you can export your Original Raw. You can export a processed version of it. But you can't export both to the same file because they are not the same thing.
Raw image files are sometimes called digital negatives, as they fulfill the same role as negatives in film photography: that is, the negative is not directly usable as an image, but has all of the information needed to create an image. Likewise, the process of converting a raw image file into a viewable format is sometimes called developing a raw image, by analogy with the film development process used to convert photographic film into viewable prints.
Sorry no we cannot call it x.nef
We can call it x.jpeg, or x.tiff or x.png bt not x.nef because a NEF is a Raw.
How could I export a processed x.nef to my desk?
I think that English is not your first language, so perhaps you need to run this through a translator oe something.
You can't export a processed x.nef
There is no such thing as a processed .nef
Just because you "wanna" do it doesn't make it possible.
