Bulb Fields Awaiting Van Gogh

Posted in Undogegorized by chamblee54 on April 14, 2019


PG was being his slack self when he saw the facebook friend. Bulb fields awaiting Van Gogh — at Keukenhof. The picture was taken “on a iPhone through the window of a tour bus.” PG played with the image for a couple of minutes, and sent a photo comment. A few minutes later, someone said “That is really impressive. How do you do that and how long does it take to learn?” Which is how this post started. PG has not written a GIMP tutorial in a while.

GIMP is the program used to create this image. It is a free download. Chamblee54 has a page devoted to GIMP, with a few suggestions for how to use it. The program was already open when PG saw the facebook thingie, so that is one step out of the way.

1 – Download the picture. Double click on the picture, until a separate page opens. Right click on the picture, and go to “Save Image As.” Give the picture a name, and put it in a folder.

2 – Open the picture with GIMP. Crop the picture. PG has 720 pixel columns on his blog. The best shape for this is the golden rectangle. For 720 pixels wide, this means 447 pixels tall. Find a section in the picture which has most of the needed elements. Click R, for the rectangle tool. It has a fixed ratio today of 720:447. Draw a rectangle around the part of the picture that you want to use. Click Image/ Crop To Selection. Click Image/ Scale Image. Type 720 in the Width field, and click Scale. If Height is not 447, click on the chain link symbol to the right of the dimensions. The chain link will open. Type 447 in the Height field. Click Scale.


3 – Since the picture was taken out of a bus window, it is not perfectly aligned. You want the dark green section to be flat, rather than rising up at an angle. Use the Perspective tool, Shift+P. Drag the bottom left corner down, until the dark green section is flat. Drag the top right section, so that the horizon is flat. Click Transform. Click Ctrl+H to anchor the selection.



4 – Click Colors/ Levels. Click Auto Input Levels/ OK. This will change the way the image looks.


5 – Click Filters/ Artistic/ Waterpixels/ OK. Click Edit/ Fade Waterpixels. Click on the Mode menu, scroll down to Darken Only, select Darken Only, Click Fade.


6 – Click Filters/ Artistic/ GIMPressionist. This filter uses Presets, which is a system for making brushstrokes. The Preset PG used in this picture is custom made for his use, and is not available in the standard GIMP. If anyone wants to know how to set up this Preset, leave a comment. You can also Click Filters/ Artistic/ Van Gogh. This is described as “Special effects that nobody understands.”


7 – Click Colors/ Hue Saturation. Click Alt+S twice. Type 99 in the Saturation field. Click OK. Click Colors/ Color Balance. Under Select Range to Adjust, choose Highlights. For Cyan/ Red, type in -22. For Magenta/ Green, type in -22. For Yellow/ Blue, type in -22. Click OK.



This should give you a picture that resembles, sort of, a painting Mr. Van Gogh would have done. Absinthe is not required, and you should have both ears intact when you are done. Other GIMP tutorials can be found here.
