Quick Bounce
Sherry Galeazzi
With all of the bounce discussion going around lately, I thought this would be a nice video post to address a simplistic way to utilize the bounce of your wedge, regardless of the grind, loft or bounce angle. Rotate the face open and forget the "normal" square face condition. Create a new standard shot and stay in the open face bias. When the lead edge is rotated open at set up, the lead edge of the club rises and more bounce will be exposed on the strike compared to square face methods. This technique is employed by numerous world class wedge players because of its effectiveness. Remember, when the lead edge "opens" to the right of target, loft will be added, but also point to the right of the target line. Because of this, make a simple adjustment: rotate your body slightly left so you can get the intended launch direction correct. Use the bounce to conquer into the grain and muddy lies, but also when just hitting "normal open face" pitches.
When you perform bounce flash photography with the camera placed in the portrait orientation, you can use the quick shift bounce function to reproduce the bounced light consistent with the one produced during photography with the camera placed in the landscape orientation. In addition, you can use the operation console in the proper orientation as well.
When the flashlamp is tilted sideways by 90 in either direction for flash photography and the camera is placed in the portrait orientation, the top and bottom of the photographed images may appear darker. In such a case, use the built-in wide panel or tilt the flashlamp back to the upright position.
When [AUTO] is selected for the flash coverage (zoom) of this flash unit, the coverage is adjusted automatically to the wide angle during 90 sideways bounce flash photography. In such a case, the flash range may be reduced compared to the one available for bounce flash photography with the flashlamp tilted back to the upright position.
LumiQuest Quik Bounce (best flash diffuser rating: 8.94) is a new flash accessory from a well known manufacturer. This reflector is designed to deliver more than other LumiQuest products flexibility in fast-paces environments, such as weddings, for example.
Event photographers often find themselves in a situation where they go back and forth between areas with no ceiling and areas where there is a ceiling to bounce of. They want to be able to adjust to the changes quickly and make use of a ceiling when available.
Closing both doors creates a light source of about 7.5 in by 5 in (190 mm x 130 mm) and makes all the light go forward. This is a rather large light source that softens the light significantly especially if you are not too far from your subject.
Opening the door leaves the Quik Bounce with about 20% of the power in comparison with the previous configuration. The 80% of the light goes through the opening to be bounced off of a ceiling or, may be, a wall depending on how you set your flash head. This is a very useful setting because it creates a natural looking lighting (that comes from the ceiling) and also produces enough fill light to soften the shadows.
To keep the doors closed or open LumiQuest designers put several small Velcro pads on the outside surface of the Quik Bounce reflector and the doors themselves. We find that those pads work very well. However, we're left with a feeling that the doors are not closed as tight as you may want them to. This does not affect performance though. It's more about the feeling rather then the functionality. And actually, you can close the doors tighter if you pull them towards each other a bit. So, let's just point out one more time that this a very minor issue that shouldn't be considered as a drawback.
LumiQuest advertises that Quik Bounce delivers two light ratios: either 100% forward, or 80% to a ceiling and 20% forward. We believe that a third options deserves mentioning as well. You can easily get 40/60 ratio, meaning 40% of the light go to a ceiling and 60% go forward. Obviously enough that is achieved by having one of the doors open and the other one closed. Even though the Quik Bounce is not designed to be able to keep just one door closed, it is very much possible and presents a nice bonus.
Another good improvement done by LumiQuest, as opposed to other family products, is the way Quik Bounce attaches to a flash head. Reflector is designed to be mounted on a narrow side, thus, practically eliminating the need for a flash bracket. When transitioning from a horizontal shot to a vertical one all you need to do is tilt your flash head. This places your light source above the lens axis, which is often the purpose of using a flash bracket. This approach to attaching a light modifier to a flash head is used by many other manufacturers and LumiQuest is smart in adopting it.
So, LumiQuest Quik Bounce is a very nice addition to the LumiQuest family of flash light modifiers. The quality is great. The unit gives a nice feel of a solid and very well built device. Light source it creates is on the larger side. And different light ratios are very handy. We'd expect Quik Bounce to be at least as popular as the other LumiQuest products and can see the company selling a lot of these units.
So back to the rules on double bounces? The question that usually comes up in these situations is not just whether a double bounce occurred, but who gets to make the call as to whether it occurred. If you're playing in an officiated match, obviously the official would make that call. But, as most of us are playing in unofficiated matches without the luxury of a tennis official, we have to look to The Code.
Well, you're probably wondering what actually happened in my match? My partner is very, very nice and I know she felt bad for talking during the point so she offered to replay the point. I wasn't going to argue about that with my partner so that's what we did, even though I'm sure that point was ours. And we ended up winning that point anyway so it's all good!
The big takeaway here is to remember that the double bounce is called by the person hitting the ball. It's a hard call to make sometimes but, if you're on the other side of the net, you just have to have faith that the vast majority of people are going to honestly make the call the best they can.

The quick bounce in padel is one of the most characteristic shots when we play our favourite sport. In this post we will look more in detail about the technique behind getting the ball to bounce quickly, how to play the shot, and when to use it.
Before starting to deal with the different points mentioned, we should comment that the early bounce in padel is probably one of the most complicated strokes to execute, so we should try to play it only when necessary and not overdo it.
To talk about the technique we are going to break down the stroke in 4 points: waiting position, readiness, point of impact, and finishing, explaining each one of its characteristics.
One aspect that we have to take into account in the early bounce are the grips (either forehand or backhand), since we can try either a floated or flat angle approach depending on the ball we want to play and the position of the court where you are standing.
We have to try to hit shots without excessive speed, in order to counterattack and win back the net. We must not overdo the early bounce in padel in this situation, as we run the risk of leaving the ball easy for the opponent to finish the point.
In this position we usually find ourselves in two main situations. One of them is when we serve and go up to the net. If the opponent manages to return to our feet, we must play a ball without excessive risk to the back of the court. The other situation is when we get a short ball and they manage to play a ball to our feet.
If the opponents decide not to go up, we will play a comfortable shot to the back of the court, but if on the other hand they decide to go up to win the net, we will have to try to generate a ball that is not above their waist, to be able to keep the initiative in the point.
We move on to the attacking position, and here we find a very common mistake, and that is to want to play the bounce early in padel by radically changing the direction of the ball. If the opponents have played a good shot and decide to go up to win the net, we will have to play the ball in the same direction or to the centre of the court. If we change the direction of the ball we run the risk that they will anticipate us and we will not have time to move to the other side.
Because processing information with light can be more efficient than with electrons used in current devices, there is good reason to confine light onto a chip. But light and the bits of information it carries tend to leak and scatter out of the tiny components that must fit on a chip.
"We want the bits of information that we are sending in the waveguide to travel along tight bends and simultaneously not be lost as heat. This is a challenge," said Zubin Jacob, Purdue assistant professor of electrical and computer engineering.
What makes the waveguide cladding so unique is anisotropy, meaning that the cladding design enables light to travel at different velocities in different directions. By controlling the anisotropy of the cladding, the researchers prevented light from leaking off track into other waveguides where "crosstalk," or mixing, of information would occur. Instead, bits of information carried by light bounce off by "total internal reflection" and stay strongly confined within a waveguide.
