Today I tried to practice with glass material after a week of silence.The main difficulty lies in the control of the light band for the hook edge and the background light for the control of the refraction effect of the liquid.
The first difficulty is relatively well solved light control accessories in the strip soft box can really not be replaced with baking paper. Of course I did not deliberately play the effect of gradient because it is not the actual project just practice I know the general location can be.
The second difficulty lies in the background material and the location of the background light source and the direction of the subject, which can only be debugged while adjusting the location of various directions.
That's about it.
