A matter of texture
After a first ride through the blog post at 4:00 in the morning, the way the challenge want to go was a bit fuzzy to my sleepy brain.
Now I have had my coffee, and I read once more, it's more clear and understandable.
There's still one point hurting my brain: texture.
To be honest, this is a photo concept I always have difficulties to understand, probably because of the French word "texture", which send you back to a physical feeling, when you're touching the surface of any object.
How do you understand, and could you try to give me some help about this word, please? :)
As far as I know, the meaning of texture is not so much different in English than in French. Even in French, texture is not limited to the physical feeling but also the visual appearance of an irregular surface. (See definition 3 here.) Think about a piece of wood: it has texture. Even if you smooth it out so it doesn't feel rough anymore when touching it, it can keep a visual texture.
That said, there is often a relationship between physical and visual textures because physical irregularities can be accentuated with light and shadows. And these can, in turn, be accentuated in post-processing, for example using clarity like Boris mentioned in the blog post.
More thoughts that involve LEGO and photography...
Take a slope brick. If you touch the sides, it is very smooth like most ABS pieces. But the slope is more irregular. It's something you feel when touching and can see if you look closely. It's also something you can photograph.
Depending on how you would light the brick, the texture would be more or less pronounced and visible. If you have very soft and even light, the texture won't be strong and might not even be visible. If you have more directed light, and thus more shadows, it would be more visible and obvious to the viewer.
It's not something we use a lot in LEGO photography because ABS is so smooth. But if you take other toys they can have more texture and it's something that can be accentuated with light. The first examples that come to my mind are the Schleich dinosaurs.
Thanks Maëlick for this answer.
The use of the word « texture » appeared in the softwares a long time after I get my processing routines, and I never explored this way.
Time to change that! ^^
Well, you can use it to increase or decrease the (visual) texture effect. But there might not be much to increase or decrease if your photo mostly includes smooth ABS plastic :D
Maybe I should make a post about it after taking photos with the Schleich dinos that I got yesterday :-)
