Picture of the week - A flower and layers in gimp

No comments
When I was in JianShui, I took a picture of a red flower in the rain in front of a traditional building:
flower_in_colour

Even though I liked the composition, the picture felt a bit pedestrian. I tried converting it to black and white, using the channel mixer to get the red flower almost white, which I liked much more immediately:
flower_in_black_and_white

Then I got the bright idea to open both pictures as layers and go wild with layer modes. The lighten / darken modes (lighten only, screen / darken only, burn) didn't really do anything interesting, but HSL colour (colour picture upper layer) ended up with a much nicer colour picture than the original (I like how you can see the rain drops clearly). This makes sense, HSL colour takes the colour and saturation from the top layer and applies it to the lightness of the bottom layer. I had previously used the channel mixer to lighten up the red from the flower. That is a really interesting option, I will keep in mind for future pictures.

Now for really experimental: Difference mode calculates the RGB values from the top layers minus the ones from the bottom layer. In case there is a negative number in converts it to positive. For example most of the red flower has values around (180 red, 5 green, 0 blue) and (180 red, 180 green, 180 blue) in the black and white image. The outcome image then had a teal flower with (0 red, 175 green and 180 blue). Any similar colour on both pictures (such as the white sky) would turn to black (0,0,0). It's a cool effect:

Now divide has even more complicated calculations it takes the RGB values from the upper layer * 256 and divides it with the RGB value of the lower layer + 1. The result is that similar colours go white and thanks to the channel mixing I did with the black and white picture only the red flowers and green leaves were left. I really like this one:

Picture of the week - This photo upsets me

This photo upsets me. I did not have a tripod with me when I made it, so I had to set the exposure really carefully. After editing the RAW picture I was really pleased to see that the inside of the shop was well exposed. And then I noticed that I had not been standing right in front of the shop, so the lanterns were off in relation to the signs behind it. By then I had already left JianShui and there was no way to return and retake the picture. It could have been perfect.



Picture of the week - Kunming

Will I ever make it off the island again? Who knows? Anyway, here is a picture I took in Kunming, China. In October 2018. It was 25°C.



It's a collage...
