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:




Picture of the week - a tree

No comments
For a long time I wanted to take the picture of tree branches against a dark sky. On our Easter trip I finally found a tree standing by its lonesome, sunilight hitting its branches. I used a red filter and thanks to the low sun got a nice gradient effect.

Unedited picture:


Picture after cleaning the background, emphazising contrast and adding a soft light layer with a white to black gradient to enhance the effect.

Ansel Adams inspired pictures of Borgarfjörður on Good Friday

No comments




This Good Friday we went for an "outing" (as my ex-flatmate calls it). The weather was actually really sunny, but I had just seen a documentary on Ansel Adams, so instead of cheery and sunny I went for dramatic and black and white. Both pictures were taken with a wide lens (23mm), aperture of f8 (as large a depth of field I could get in this light from a moving car) with a red filter and increased contrast.
