TIP 3. The Finger Tool (Smudge Tool) should be used extremely rarely and in no case for mixing colors!
Quite often, beginning artists, not knowing that colors can be mixed thanks to Opacity (Flow) and Flow (Press), begin to mix, it would seem, the only available way – the finger tool. And then it becomes so habitual that even comments like “don’t use your finger”, “you can see that you used your finger,” “very blurry,” etc. can no longer force them to retrain. And the hedgehog, continuing to cry and prick, climbs again and again on the cactus, until a local crisis occurs and the person simply stops listening to what they are saying to him.
So, so that this does not happen – I say right away. We exclude a finger as such for the near future in general. It is convenient for them to do little tricks, correcting or distorting the lines. But they do not mix colors at all. Because the effect will be like … right, like a finger smeared paint.
As an example I will give just such a small picture. The circles are very small, but the essence should be clear. Of the people I interviewed, who are not related to drawing and do not understand what and how blending was done, the majority stopped at the attractiveness of option 4. That, in fact, is true.
Picture 1. This is the base of flowers. We have a circle, shaded shadow and light. In fact, we just have three spots that we need to mix.
Figure 2. As you can see, the result was not bad, but blurred. And with large image sizes, we get just one solid “soap”. Such color mixing occurs when using a soft brush or using a finger with soft brush settings. In the larger picture you can see how the colors mix with your finger. As you can see, we just have a blockage of the line and practically no intermediate colors are present.
Figure 3. Everything is very bad here. I made mixing in this circle using my finger with the settings of a solid brush. Unfortunately, many aspiring artists use this option and it’s terrible, believe me. In the larger version you can see how scary everything looks. Of course, many craftsmen manage to bring the use of the finger to perfection, but almost a few manage to do so that the work does not give the “finger effect.”
Figure 4. Well, here we mixed for different values of Opacity with an ordinary solid brush. As you can see, the option looks more voluminous due to the fact that as a result of blending, we got a lot more shades and transitions. Well, by itself, it can be seen what a strong difference and advantage over this method over others.
Summing up, I repeat – never use your finger to mix colors.
