Picture of the week - Narcissus

No comments
Who fell in love with his reflection. I am playing with light painting at the moment, using the last dark nights until 24h sun. These are 10 pictures made with a mirror, a flashlight and a tripod at 70mm/ƒ/11/1s/ISO 100. I then combined them in GIMP to create the last image.



How to edit:
Open the pictures into GIMP as layers and open "windows"-> "layers". Use the "lighten only" mode for all layers except the base layer.
To make the gif I right clicked on a layer and selected "new from visible". I moved the new layer on top (the gif animates from bottom to top) and specified in the layer names the delay between frames eg: "Layer 1 (500ms)". I set the first (combined) image with a longer delay (2000ms). Export as gif and make sure not to check "Use delay entered above for all frames" in the dialogue.

Picture of the week - Reykjavík in Black and White

I made that picture last year when winter actually had snow. This year it was mainly rain and storms. Last week there was even a thunderstorm, which I have never experienced in Iceland. Thunderstorms occur when cool air collides with warm air. One of those is rare in Iceland.

Picture of the week - HDR pictures with gimp

No comments
I don't actually like the look of HDR pictures, especially of landscapes. I always find they look fake. But for learning purposes I decided to create an HDR picture with gimp. I took three pictures of Kirkjufell in Grundarfjörður, with normal exposure, -2 and +2 exposure. I did some basic white balance correction and normalizing for each image.



Then I opened the pictures as layers in gimp (File → Open as Layers). with the normally exposed as the base image on on bottom and the overexposed image on top. I opened the layer dialogue (Windows → Dockable Dialogs → Layers) and chose "Add Layer Mask" for the underexposed picture by right clicking on it in the layer dialogue. I chose a Grayscale copy of layer as maks.
I then did the same for the over exposed image, but inverted the grayscale layer mask (Colors → Invert).
Layer masks determine which part of the layer is transparent and which opaque, with black being full transparency and white full opacity. Thus the lighter parts of the underexposed and the darker parts of the overexposed image are layered over the base image. I then played around with the layer modes using screen (other possibility = addition or normal) mode for the underexposed and burn (other possibility = multiply or normal) for the overexposed. See here for an explanation for layer modes in gimp. I played around with transparency of the two layers until the result was less fake looking. The I merged the three layers together and corrected the colour balance again. Here is the result:
