RAW Conversion Cropping Image

Sun Aug 21, 2011 11:57 am

Hello all,

When I convert a Nikon NEF file to standard RAW format using Adobe DNG Converter, the image is cropped slightly when opened in Photoshop. I.e. the extremities of the original image are lost. Does anyone know how to fix this?

Thanks,

Peter

Why bother doing this at all?

Photoshop can process NEF files.

My Photoshop can't.

I guess my version is obsolete.

Perhaps you two were unaware of the fact that Adobe does not retroactively update its previous versions of Camera Raw when adding new camera profiles. I guess it's a sneaky way for Adobe to force you to buy the latest version of Photoshop if you want to use a newer camera. Let's say for example Peter is using a D7000. In this case, the D7000 is only supported by ACR version 6.3 or higher. ACR 6.3 in turn can only be used with CS5, and not with CS4, CS3, etc... The only way around this (other than buying CS5) is to convert his .nef files to .dng which can be opened with any version of ACR/Photoshop.

Peter, to your original question, I have never encountered this problem before. Is there nothing in the converter settings that might allow for the full file size to be retained? Perhaps the issue is when opening up the .dng in ACR rather than the actual conversion process to .dng itself? If you want, you can send me a file, and I'll see if I come up with the same results.

Have a look at this

http://www.luminous-landscape.com/contents/DNG-Recover-Edges.shtml

It may explain - and solve - the problem you're having.

Cheers,

Or you can just obtain an image converter for free or very cheap that handles .NEFs. You can edit and convert to TIFF or JPEG or anything else but RAW and open in any version of PS.

That does sound like the problem I'm having - I'll try that program. Thanks Colin.

A working link to that littlie program is here:

And it does work!

This translates to 14 pixels in width, and 9 in height. Not a lot, but it can make a difference in some cases, and it's a very quick step.

Thanks a million, Colin!

Providing you nail the exposure to within workable limits and assuming you'll never sell a TIFF then yeah, I'd agree with you John. But I actually love working with RAW files; the amount of non destructiveness in the editing process is quite remarkable.
