Different angles & distances will help give you a more accurate estimate before seeing your damage in person to check the rest of the variables that can change the price and repairability of your dents and dings.
These four pictures show the dented hood with just a natural reflection which only gives the basic size and depth of the dent.
This second group of pictures is an example of one of the special reflections paintless dent repair technicians might use to properly evaluate the damage and do the repair. When placed at the correct angles and distances they can show the exact shape size, depth, and crown of the damage. Without the proper reflection, this damage could never be repaired or even given an accurate cost to repair by even a trained professional. During repair, a paintless dent removal technician will adjust the reflection no less than 10 times.
