For light problems in portrait photography, please consult a professional photographer @

Look at the picture only by feeling, not necessarily correct.

1: The possibility of studio lights is relatively large, and it is possible in Three Lamps District if it is over 400W.

2. The lack of clarity may be the result of self-compression before uploading or over-compression when uploading.

3. The constant brightness power used in the studio is not low, generally more than 600W W.. Three primary colors, quartz lamp or halogen lamps are available.

It's hard to say, it depends on the effect of previous film production.

For reference.
