Re: Compression v/s Size(Dimension)

Okay - double the finest detail. Digital sampling should always be performed to a degree of detail that is greater than the human senses, in the finest context the item may be used. This is also true for digitizing sound recordings. Half-tone images, such as those published in books and newspapers, ...

Re: Compression v/s Size(Dimension)

You have touched on a subject I wish was asked more often. I am the self styled “media guy” at the Museum of Our Industrial Heritage (industrialhistory.org). We are limited in budget and own or have been loaned many wonderful vintage documents and images. I also copy frame-by-frame movie film as raw...

Re: ImageMagick in movie restoration

They were 5208 x 3477 raw DNG image files. The frames were intentionally over-captured. The rendered film was properly cropped to present the correct aspect ratio with the maximum true image area possible to conserve.

ImageMagick in movie restoration

I wish to thank the developers and forum administrators for their great effort and support. I have been attempting a "poor man's" movie restoration system, and partly thanks to the ImageMagick folks, I now have something to show for it. I am using Imagemagick to convert DNG raw files out of my digit...

Re: How to convert DNG without normalization?

Bingo! Thank You
My problem was solved by editing 'delegates.xml'. I replaced your dng decode command option from '-w' to '-W', and I was done.

Re: How to convert DNG without normalization?

Try mogrify -format png DNG:somefile.DNG Thank you for the reply, but this suggestion doesn't affect my problem. The contrast still gets normalized. This prevents me from being able to control any levels across an entire image sequence. A 'fade to black', becomes a dissolve to noisy grey. Light vs d...

How to convert DNG without normalization?

I am using my Canon DSLR to capture 16mm movie film. My camera creates raw DNG format images. Any conversion I try (such as mogrify -format png somefile.DNG ) results in a normalized image, rather than one with the original brightness, contrast, and whitebalance values. This default behaviour isn't ...
