Tennis balls
The game of tennis (more properly known as lawn tennis) was developed in the 1870s from the game of royal or real tennis, which has been played for centuries. While both games are similar, in that they are both based on two or four players opposing each other from different sides of a net hitting a ball back and forth, the type and size of court, method of scoring, etc., are very different.
Real tennis balls have been traditionally made from a spherical stitched envelope of leather or cloth stuffed with rags, horsehair or similar material, while tennis balls have always been based on rubber.
From the beginning of lawn tennis in the 1870s, India rubber, made from a vulcanisation process invented by Charles Goodyear in the 1850s, was used to manufacture lawn tennis balls.
Originally tennis balls were made solely of rubber, but the wearing and playing properties of the balls were improved by covering them with flannel stitched around the rubber 'core'. The ball was quickly developed by making the core hollow and pressurising it with gas. Originally, core manufacture was based on the 'clover-leaf' principle whereby uncured rubber sheet was stamped into a shape resembling a three-leaf clover and this was assembled into a roughly spherical space by machinery adapted for the purpose. Chemicals generating pressurising gas were added prior to closing the assembly and these were activated on moulding the core to a spherical shape in heated cavities. The process was used for many years until the precision of the game demanded a higher degree of uniformity (particularly relating to wall thickness) than could be obtained with the clover-leaf method. Now it is usual to compression mould two separate 'half-shells' which are assembled together to produce a 'core'. The original flannel cloth was replaced by special 'melton' cloth made specifically for the purpose and the stitching has been replaced by a vulcanised rubber seam.
Historically, balls were either black or white in colour, depending on the background colour of the courts. In 1972 the ITF introduced yellow tennis balls into the rules of tennis, as research had shown these balls to be more visible to television viewers. Meanwhile Wimbledon continued to use the traditional white ball, but eventually adopted yellow balls in 1986.
Until high altitude balls were introduced into the rules in 1989, only one type of tennis ball was allowed. The Type 1 and Type 3 balls were introduced into the rules in 2002.
Other properties of the tennis ball have changed over time. The range of forward and return deformations - the change in the ball's diameter under an increasing and decreasing load of 8.165 kg - have varied over the years, reaching their current values in 1996.

s strobed in the cb
Nothing much really. I was with s at the bean tnite testing out my new Sigma 10-20. hehe..! I just love how much of the scene the lens takes in. Just look at the amount of negative space in the picture. I was 6-8 feet away from him. The image is uncropped.

Uncle! Take my picture!
This little cutie was eyeing the SB-26 I had mounted on my monopod. Maybe she was just curious about seeing this crazy man in front of her carrying a huge stick around under the hot sun! Haha! I promptly asked her if she wanted her picture taken...which she kindly obliged in spades!!! =)

Balancing man and nature...
One of the last shots of the day. The light was fading quite fast so I decided to take the opportunity to try out a few shots of strobing the landscape. Inspired by something that I had read on strobist, I wanted to see if I could pull off something similar. Result? Similar? Yes. Spectacular? Hardly. But spectacular was not the goal here since I only had a 2 minute window to pull off the shot. Chimping the power of the strobes up and down to find the "sweet spot" was easy enough especially with souljah there with me. We actually wanted to try "painting" the landscape with light but the flashlites available weren't quite up to the job. Maybe next time...

Strictly Beautiful Cupcakes
Another set taken from a session done last year for strictlybeautiful with Souljah. A bulk of the pictures were lost from the laptop's hard drive but a few were able to be saved since they were still on the SD card. Thankfully Souljah managed to rescue the session with his pics. :s I believe he has a shot of the set-up on the forum.

Finding Nemo...
Nothing astounding really. I just bought an SB-26 second hand earlier today from "that place in Bandar" (LOL!) to go along with the Sigma EF500 that was already in my kit. I didn't get a chance to test it out much when I bought it, so I went about taking a few test shots around the house just to make sure everything was in fine working order (as the seller had claimed!). Thankfully everything worked a treat...it even triggered optically! Now all I need is a couple more and I'm set!

Bimbo Loserrr...
An impromptu session done yesterday. Thankfully the model was able to make it to the shoot on short notice. If anyone's wondering why the title of the post is as such, no I'm not being mean but that was what the model referred to me as BECAUSE I had contacted her at the very last minute! Man..not only was I a "bimbo" but a "loser" as well!!! Hahaha! Anyways, this shoot has been in the works for quite a while already but it was only yesterday that I was able to do it. Just another Sunday afternoon =) Muchas gracias again to Souljah for the assist.

Me and my pink bike
When I said 'me', I didn't actually mean 'ME'. This was one of the shots from a session I did for a friend of mine. She wanted some updated pics of her three kids. Kudos to Souljah for the assist. We always seem to work well together for some reason. Maybe its the 'sumit'. Haha!
Initially she just wanted some indoor shots of her kids but we managed to persuade her to take them outside for some outdoor shots "Bruneian Strobist stylee!". Needless to say she was quite happy with the results. The couple of shots that you see here are just a sample of the 100 over shots I took over the course of the session.
All three were a pleasure to work with, especially the youngest. She was such a gem! Quite the natural in front of the camera! =)
On a side note, I definitely need to get my sensor cleaned! Its kinda filthy. I'm spending waaayyy too much time cloning out the dust spots in CS3!

Testing...testing...
Experimenting with off-camera flash lately. My two friends were more than happy to serve as test subjects last nite. You know what they say..."If the fish ain't biting, model!" LOL!
