Can't be done. High Dynamic Range is a technique for taking multiple photographs, at different exposures, and combining them into one. If you have only one RAW file, you can't create any number of differently exposed images from it. However, you can create effects that look similar, using "-sig...

My script above has a bug: "-clone 0" should be "-clone 1". In this scan, the "alpha" channel is actually (I think) infra-red. In theory, it ignores the image in the photographic negative, and picks up only dust on the film. Converting it to an image, it seems to me tha...

Try using "-density" and "-interline-spacing".

"convert" needs an output filename.

convert sparse_color.jpg \( test.jpg -profile "xx.icc" \) -gravity northwest -geometry +10+10 -composite test22.jpg and the image is as dark as with no profile specified. I don't get it. Your image already has xx.icc profile applied. Your command would convert it to exactly the same profi...

I have no experience of this methods of scanning then removing dust, but the following (Windows 7 script) gives a reasonable result. convert ^ scan0003.tif ^ -set colorspace RGB ^ -colorspace sRGB ^ ( +clone -channel RGB -statistic maximum 4x4 ) ^ +swap ^ ( -clone 0 -channel A -level 70%%,75%% -sepa...

I don't print via PDF files, because that just adds an extra layer of complexity. A4 paper is 297x210mm (11.693x8.238 inches), but most printers can't print up to all four edges. If you use ImageMagick to convert a load of images to a single PDF file, the pages will be different sizes and aspect rat...

I happens to me. I sometimes figure out a complex solution to a problem, completely overlooking a simple solution -- a solution that I always knew but had forgotten.

I sometimes think I have forgotten more than I ever knew.

"+append" should do it. If the input has one image, "+append" does nothing. If it has many images, they are placed side by side. As a command line:

On Windows 7, IM 6.7.9 and 6.8.5, with or without double-quotes, the command works fine.

I am not 100% sure that it is strictly related to IM, because even the thumbnail of the original image ( test.jpg ) in Nautilus ( i.e. the default files explorer in Ubuntu ) seems to be as dark as the result image ( test2.jpg ). But if I open this picture ( test.jpg ) in the gnome image viewer or i...

You can easily get it... ... although I don't think it's needed for a conversion to sRGB, at least on modern versions of IM.

"identify -verbose test.jpg" tells me your test.jpg contains a profile named "Darktable linear RGB". I can convert it to sRGB with: convert test.jpg -profile sRGB.icc tx.png (where sRGB.icc is a file in my current directory). Thus: convert sparse_color.jpg ( test.jpg -profile sRG...

I no longer use Ubuntu. Try:

http://www.imagemagick.org/script/binary-releases.php
http://www.imagemagick.org/script/install-source.php

Without seeing the images, it's hard to diagnose.

Ubuntu uses an ancient version of IM. An upgrade might cure the problem.
