Convert Negative

Hi,

Don't think there is a preset. If your negative is scanned as a negative, you will need to 'invert' the colors. Aperture doesn't have this feature, so you will have to invert the images in Photoshop or other similar program. After you invert the colors, you can make tonal adjustments with levels or curves.

If you are comfortable with the Terminal and command line tools, you may consider to install "ImageMagick" to convert your negatives.

The ImageMagick package offers a great selection of free image processing tools. Once installed, you can convert your negatives with a simple command line from the Terminal:

convert -negate inputimage.jpg outputimage.jpg

assuming your negative is called inputimage.jpg and you want your output image to be named outputimage.jpg.

Here is a link on how to install the binary Mac version with macports: http://www.imagemagick.org/script/binary-releases.php#macosx

And here is a manual page for the versatile convert tool: http://www.imagemagick.org/script/convert.php

If you do not have macports to install unix tools, you can get them here:http://www.macports.org/

Here is an example of a converted positive/negative pair: the image on the right shows the original, the image on the left shows the negative created with "convert -negate".
