Ask the photographer. What are the effects of these photos? (Display software name, special effect name and processing steps. )

Many softwares can achieve this effect. I recommend Mix software to you, because there are many effects and filters made by others in this software. It doesn't matter if you can't make pictures, because this is to solve the problem of novices, and this software won't destroy the authenticity of photos, and the photos that come out of P are better and more realistic.
