I want to take a kitchen knife. Product shooting. Should I choose constant light or flash? A few is better. Ask god for recommendation. Studio flash?

Both flash and normally-on light are acceptable, the main difference is that flash uses high-speed shutter and normally-on light uses slow shutter.

There is no special requirement for the number of lights, depending on personal aesthetics. Kitchen knives are generally small, and a single lamp+reflective equipment can achieve the effect. Money is rich, Three Lamps District is enough, there is no need to be too messy. Cutters are reflective objects, such as Damascus, which have texture and need texture. Besides the sharpness of the knife, you need a soft box as big as possible. So try to buy more than 400w flash.

I don't know how it is now, but the main problem is "too hot". In China, it is generally used to take pictures of children and take care of heating lamps. The current LED cold light source may have solved this problem. Constant light is usually a single light. Household LED desk lamps can also be realized. Find a piece of A4 paper as a reflector.

The magnification and resolution of 24-70 are very good. It is a good choice to take a macro lens, but most products have defects, which can be seen at a glance under the macro lens.

The studio configuration on the three pictures is very advanced Good equipment gets twice the result with half the effort, but shooting products is more about studying the theme, how to set the scenery and how to arrange the light. Photography is still thinking more.
