NEF files

Hello,

I have just downloaded and installed myphotoindex, and let it index one folder of NEF -files. Now some of the thumbnails are distored: their aspect-ratio is wrong. All photo's which are taken with the camera vertically are displayed horinzontaly with their pixels streched.

When I try full screen mode (F11) The pictures in the thumbnails are still distorted, but the large picture to the left is ok, BUT its colors are far to warm... I have a calibrated monitor, and in all other software the picture is ok.

Thank you,

Arnov

Re: NEF files

HI,

I think this is due to the fact that My Photo Index is using the RAW File's thumbnail for preview,

Can you please send me one of the wrongly displayed files to: admin at myphotoindex.com

Thanks

Asaf

Re: NEF files

Thank you for your fast response.

I did some experiments on my own, and installed a newer version of the Nikon raw file codec for explorer. New files I import now, are not distorted, but rotated (also annoying but better) . The bizarre thing is that the old imported files are still distorted even AFTER deleting the myphotoindex cache... Those thumnails are cached somewhere, and I dont' know where. The new thumbnails are alse not rotated in Explorer. Seems like a bug in the codec to me.

The rotate option is disabled, and it shouldn't be necessary to rotate them anyway, because in Nikon ViewNX and Nikon Capture the files are ok.

The main problem remains the wrong colors in full-screen mode. It seems like the white-balance is not properlry applied while rendering the image. Rendering is very slow compared to the Nikon software.

I am currently looking into myphotoindex because Nikon no longer develops PictureProject, and has no real replacement. I like the features myphotoindex has, and because it is open source I might be able to convert my PictureProject database to myphotindex. However, proper NEF support is a "should have" for a replacement to me.

Thank you,

Arnov

Re: NEF files

I have been looking further into it. My last post about the was wrong, the codec has nothing to do with it. I had two sets of pictures: one with NEFs straigth from the camera, and another set wich had been imported Nikon Software This software has the option to rotate thumbnails.

This doesn't have any effect if you use Nikon software to view the pictures, but it does in Windows explorer, end it does in MyPhotoIndex.

The reason is that width and height metadata retrieved with the RawPlugin::GetImageMetaData is used to calculate image rectangles.

This metadata is always the same for my camera regardless wheteher the picture was in "portrait" mode or "lanscape" mode. I have checked this by exchanging width and height in the DCRawplugin.cpp sourcefile, and doing the import again. Now the pictures in "portrait" mode are ok.

Is there a reason why you don't use the classes in System.Windows.Media.Imaging to decode the images?

Thank you,

Arno

Re: NEF files

Hi,

Sorry for the delay in my response (My Day job seems to be taking a lot of my time these days :) )

The only reason to use the meta-data from the RAW file is for speeding up things,

Since I wanted to use .NET framework 2.0 and not 3/3.5 (Framework size) I couldn't use the new imaging namespace. I will give that a second look and maybe write a new RAW plug-in for people with the newer .NET frameworks

Asaf.
