Sepia/Duotone

[bjwe]

My apologies if everyone already knows about this, but I came to it from first principles....

Problem: I wanted to create a sepia tone image from a bitmap photograph but after several attempts at using Sepia tone filters and adjusting colour levels in a bitmap editor I could not get the same effect as toning in a darkroom - the reason is that these techniques apply the same amount of colour to all tonal values in the image with the resulting loss of highlights and mid-tones.

It then occurred to me to try using good ol' Xara and came up with this technique based upon the tonal density of the image - and it only takes a couple of minutes to apply. If you make the sepia tone a named colour, then adjusting it is very easy.

Go to the bottom of XaraXone Tip of the Week Page 3 and find a method for converting a color bitmap directly to a sepia tone image [img]/infopop/emoticons/icon_biggrin.gif[/img]

The techniques yield different results and I find them both very useful. Thanks.
