One of the things I want to work on at this time is improving my skill in making selections. I began working on selections in my first PWDP assignment (see
here and
here) but want to spend time over the winter honing my skills. It is a helpful skill and while I may choose not to use it often in my work I want that choice to be made for artistic or ethical reasons rather than because it is in my 'too difficult' pile. This picture - originally taken as part of the TAOP lighting module - came into mind as a subject with potential. The original version (below) had a dark background, and while I was not unhappy with it I did feel that it was a bit flat. The dark background gave a reasonable contrast to the flower but did seem to drain some of its colour and vivacity.

The complex shape made it a good subject for an exercise. I had hoped to find some quick way of making the selection but didn't manage that - it took ages. I am sure that if I do a few more I will eventually pick up speed and learn ways to make a smoother and more efficient workflow. I strongly suspect that this is an area where the only way to learn is to keep working at it - like a painter learning to draw hands.
Technique and reflection
I made a selection initially using the 'Color range' option in Photoshop. I had thought this tool might work well given the uniform appearance of the background but it wasn't great. The edges needed a lot of work (I used quick mask and the brush tool to refine the selection). In addition, I found out rather late in the day that pixels that appeared selected were often only partly so - this meant a fuzzy selection that showed up when applying the background, though not really when viewed as a cut out or in 'marching ants' view. It was kind of visible on Quick Mask, in light shading. This partial selection could be useful in some cases but in a picture like this you need precision. so my learning points from this are to pay more attention to mask shading, and also to see a way if I can easily refine the initial selection to reduce this difficulty.
Having finally made a reasonable selection I played with background, using some textures from the Florabellaa collection and a range of blending modes. I wanted a background that would harmonise with the flower and set it off but without clashing with it. The thistle itself is so detailed that it would be easy to end up with just a fussy mess. Getting the right balance between flower and background was tricky (too blue and the flower got lost, too green/yellow and it looked odd, some versions were too luminous and some too dark. The picture at the top is version 11 and I am reasonably happy with it but may still revisit (I wonder if there's too much vignette?).
A friend suggested it might work well as a Christmas card so I have produced an alternative version that is slightly cooler and lighter - see below.
Only three versions this time! I had wanted to make this lighter and 'frostier' overall but found that putting any kind of overlay on top of the flower or otherwise reducing its contrast and definition just made it look busy. I think that it is such a finely detailed thing that it needs to be left largely alone.
Conclusion
This took absolutely ages to do: it would have been quicker for me to go out and buy some canvas and paint a backdrop - it is always best if you can get things right in camera. Was it worth it? Maybe not in terms of the picture itself, though I do like it, but it was useful as a learning exercise. even if I had made a backdrop and lit it well in the original I might still have wanted to change its hue and it is good to be able to make chanegs if you need to. In addition I have a request for a print as a Christmas present so that's a bonus!
I'm going to try some more of these selections over the next month or so and hope to improve. And then on to soft-edged and transparent selections...
