NEF to JPEG conversion...need equivalent NConvert parameters

Hi,

I have a number of NEF files taken with my Nikon D7000 that I would like to convert to JPEGs for archival. XnConvert performs the conversion perfectly using all the default options, but NConvert darkens the picture considerably (see the screenshot I will upload as an attachment).

I'm using the following to perform the NConvert conversion on my Win7 x64 machine:

Code: Select all

nconvert -out jpeg -o %_NConvert *.NEF
I've tried using the 'Export for NConvert' button in XnConvert but all I get is a batch file with the single word 'nconvert' in it.

Can someone tell me where I am going wrong? How do I get the same output JPEGs from NConvert as I do from XnConvert?

Kind regards,

/Neil

Hi Pierre,

Thanks for your prompt reply. The NEF files are quite large (~20MB each). Shall I PM you links to the files on my Dropbox account?

Kind regards,

/Neil

Hi Pierre,

I have sent you a PM with a link to the Dropbox folder containing the files. Please let me know if you don't receive the PM.

So XNConvert extracts instead of converting ... and NC converts but causes brightness loss ?

Good idea, but this won't fix the lib conversion / NEF decoding bug, nor the XNConvert export batch bug ?

IIRC I had problems with NEF decoding in the past, no tests recently.
