A lot of people miss “film grain” in digital images. I show how to add it (the exmple on the left is a bit over the top…). You can extract the grain from a scanned analog image or make your own digital grain with the HSV noise filter. I found these links useful: Gimp Guru and Petteri’s Pontifications. The last one is a very rich ressource. The end of the video is quite ...

In this last episode (for now…) about monochrome con- version I show you a way to get full control over the process of making a monochrome image. I “decompose” the RGB image into three layers, each containing one of the three colour channels. By adjusting the opacity of the three layers I mix the channels as with the channel mixer. But I have the full image as “preview ...

I promised a better way to convert coloured images to monochrome. And here is the Channel Mixer. It allows you to mix the amount of the red, green and blue channel of an RGB image and change the appearance dramatically. The image to the left is an example that I stole from a terrific website Cambridge in Colour. You see the original (in colour) and some outputs of the channel mixer. Then I tack...

Today I’ll start a series about mono- chrome or black and white conversion of digital images. It’s a new topic for me - so I start with a bit of background, some images from the Masters and a bit about the easy ways to make a quick conversion by desaturation and tweaking the curves a bit. The image here shows the output of the three options of the desaturation dialogue without furth...
