Pentaprism is a five sided prism with two silvered surfaces giving a non-stop deviation of all rays of light through 90 degress. Used in viewfinders of single-lens reflex cameras
There are multiple devices that emit radio waves. The most obvious is are radiod and microwaves (yes, the food cooker). Wireless applicances also emit radio waves. But don't confuse everything to use microwaves. Some applicances use frequencies instead of radio waves. Some applicances that use frequencies are toy control remotes and a garage door.
I hope this helps! Please make sure ask me if you need more clarity!
Answer:
See there are multiple ways to get a perfect shot of products to stand out but the most affective according to me are explained below :-
- Macro shooting - These are close shots u can say really close just to show the product more attractive and u can see these types of shots in every advertisement.
- Background shooting/shots - Opposite of macro shots.
- 3d shots - These are 360° shots.
Tip :- Use wide aperture like F2 and right aperture for right shots.
Hope it helps!
