GIMP detour

I’ve continued my exploration of gimp this week, enjoying lots of back episodes of Meet the GIMP, a video tutorial podcast about the GNU Image Manipulation Program. Non-textile life continues to absorb pretty much all my time and creative energy, so a predominately passive activity that still builds useful skills and knowledge is just what I need.

colour_extract_3pI took this photo a while back at the Mount Tomah Botanic Gardens. I’ve done some “post processing” of the photo (practising GIMP) and am not sure how close the resulting colour is to life…

As well as the pixelize and smooth palette tools I used before here, I’ve tried converting the photo to indexed colour and then creating a colour map. (I’ve upgraded to Gimp 2.6.6: convert to indexed with menu Image/Mode/Indexed; create colour map using Windows/Dockable Dialogs/ColorMap or add it to your tool box; the Palette is now under Colors/Map/Palette Map).

colour_extract_3_colormapThis is the generated color map. In the end I used all the software generated extractions when creating my grid, but still referred back to the original (well, doctored) photo for specific colours such as the rust red specks (stamens??) on the flower.

20090404_gridThis is my final grid. As with my previous attempts, it looks very flat and lifeless. At some stage I am likely to change my grid format, probably to fewer colours. If I want to use these as a guide for dyeing yarn I would probably want fewer base colours, then mix them and play with dilution as I am painting the yarn.

fire_colourmapI went back to my fire photos and did the indexing/color map trick with those. This first example is from my own photo, shown in this post. It has a lot of the flickering flame combined with charcoal, smoke and ashes that I first wanted, although not the glowing red.

fire1_indexThe second is from a photo of a more brightly burning fire (from a photo I found on the web, so I won’t reproduce it).  I’m surprised by the pinks and purples that the software found – not at all my idea of “fire” colours.

There will be weaving soon, I promise! I actually have some Finished Objects from a few weeks ago, waiting for their moment in the limelight. In the meantime, Monday morning is approaching and my weekend list of chores still looks like Mount Everest.

    I’m doing a catch up on your blog

    … On my iPad and just tested that posting worked and love your need for a passive activity that builds useful skills. That is where I am at with my rag rugs! Maybe your grid structure looks flat and lifeless as the colours are all shown in equal parts – compared to the indexing/colour maps which retain the tiny points of high light colours.
