Bounce / Diffuse

Last time, we have been discussing about the Flash / Blitz, now we will try to study about Bounce, Bounce flash is a flash how to toss a field so broad that light comes in a wider angle. For example, using the ceiling or wall in the room. If an external flash attached to a digital camera connected via hot shoe, the flash should have a tilt facility to reflect light. If the synchro is connected via cable, then we can install flash on the bracket to the position slightly upwards / or addition to holding positions with such position and must also be precise so that light falling on an object.

Some of the things we need to note in using the bounce flash is this:
1. Distance to calculate the f / stop is not changed into the distance and the camera changes to an object but a short distance passed by the light flash. Normally in the 45 ° tilt angle we'll widen 1 APERTURE and stop at the 90 ° tilt angles we expand the 2 APERTURE stop. Of course, this brief guide only, depending on the technical implementation in the field.

2. Regarding the no. 1 above, the distance the ceiling or wall in the room should not be too far or it will be useless.

3. Use field always white and not dark. Colors other than white will cause the image contamination while color is dark color will absorb the light flash.

4. Note the occurrence of the reflection can occur on the other side light. For example, if we toss to the ceiling then we will get shadows under the nose or chin and if we reflect on the wall to the left then there will be a shadow on the right. To overcome this we can put a bounce card on the front of the flash so that when we are reflective to the top / side we still have a light that is not too strong which leads to the front and netrally shadows appear.

To take a vertical photo, will be easy if we use a cable connection because we can easily set up to flash by using the bracket or held. But if the connection is our hot shoe flash then make sure we have the facilities swivel head so that we can play facing up. Great if we can have a flash-in tilt and swivel. This will accommodate most needs us.

When we use a diffuser, we actually prevent certain areas from the light to flash. This reduces the strength of the flash we use it. If we use a diffuser is the result of the purchase, then we can read how APERTURE compensation when we need the exposure. Usually there is paper in the box or manual. If we decide to create your own, then we can perform the experiment many times to get the numbers to fit the required compensation other times, study and learn to better results.
