788 Setting Up Your Digital Camera For HDR Shooting
Youâve probably heard of High Dynamic Range (HDR) Photography, itâs made quite an entrance into the world of digital photography.
If you havenât, the HDR process is accomplished by taking multiple exposures of a high contrast scene (usually a landscape or cityscape), at different levels of brightness, and then combining the best light from each exposure into one image.
The end result is a stunning image that very closely resembles how the human eye views a scene. This process of digital manipulation has caused a bit of controversy and debate in the world of photography, especially with images that are âover-cooked.â One thing is for sure though, HDR is here to stay. When done right, this unique and in depth processing technique can produce beautiful works of art that mimic the way we view and remember a landscape or scene.
The above image is an example of what HDR processing can produce. This image, taken from the Big Island of Hawaii, would not be possible without HDR processing. It was taken around noon, the harshest light of the day. The first image is the best image my camera could produce given the situation. While still beautiful, there are obvious problems. Get ready, this article is going to show you how to take your digital camera and turn it into an HDR shooting machine!

Inside Alesis A6 Andromeda
Here are some pics Iâve shot during the reconnaissance inside my A6 (taking some measures before pimping it with some custom made wooden cheeks). Itâs quite surprising that its guts are not that complicated as it may seem looking at itâs interface. Very clean layout and good engineering (with tons of silicone glue, WTF?). The only con is that in order to remove those original cheeks I have to disassemble all the PCBâs attached to the front panel â and probably all the pots! Teh drama.
Sound synthesis and sound design
Music has brought pleasure and entertainment to mankind throughout the whole of history. Each person is by nature equipped with one of the most elaborate and emotional musical instruments; the human voice. Whenever people feel good music seems to fit the occasion, and it is considered quite natural to hum or sing a song. Musical instruments have brought their own moods to music and at the current moment in human evolution there is an enormous variety of musical instruments available. The twentieth century has seen the development of a range of new and exciting electronic musical instruments. These electronic instruments are very flexible, they can produce a wide range of timbres and can be amplified to whatever loudness level sounds best for the occasion. Most of these electronic instruments are played by a keyboard, but in essence the keyboard can be replaced by any electromechanical device that is able to transform a movement caused by a human interaction into an electrical signal that can drive the sound generating core of the electronic instrument.
All sorts of technical and scientific developments have helped to create electronic instruments and the human interface to play them. Still, music is an art and not really a hard science, although music and sound have for a long time been subject to various scientific research. An important realization is that science can not really explain why much music is such a pleasure to listen to and such a joy to make. Which is not a bad thing, as probably no one is waiting for science to take the fun out of music by applying formalized rules and templates on what is also subject to âfeelâ. So, although this book covers techniques that lean heavily on scientific research, the application of these techniques will in general be aimed at creating fun. There are a lot of professionals working with sound and even more people that make music for their personal enjoyment. Mastery of sound synthesis is valuable to all of them. Still, it wonât be easy to please everyone with one single book, as some people will be more interested in how things work and others might want practical examples that just work. The aim of this book is that it can at least be used as a practical guide in workshops and courses in electronic music, covering some essential basics that are needed to operate the equipment used in sound synthesis in a way that makes some sense. Additionally it can be used to explore techniques to find out how they can help in the development of oneâs own musical style.
Sound synthesis is the art of creating sounds by using suitable electronic means, using either analog or digital electronic devices. Sound design is the art of creating particular sounds using sound synthesis techniques. The definition of sound design as used here might be confusing to some, as the name sound design is also used in the discipline in industrial design that occupies itself with how mass produced objects should sound. Examples are how the sound of cars or ladyshaves are âdesignedâ to sound pleasing while in use. Which of course has nothing to do at all with music or sound synthesizers. This book puts the emphasis on the various synthesis techniques for musical purposes and how to setup sound synthesizers to create a large range of characteristic musical sounds. The art of musical sound design is left to the artist.

426 steampunk brass synthesizer blows my mind on [technabob]
I always thought analog synthesizers were inherently retro. Just not quite this retro. This unbelievable steampunk modular synthesizer features tons of dials and intricate brass etching throughout. All of the buttons and knobs were hand lathed, and the synth includes a number of antique parts as well.

423 MACBETH STUDIO SYSTEMS
Welcome to MacBeth Synthesizers!
LATEST NEWS: 20/07/09 please scroll down for infoOver the last year and half or so, more products have been developed. Work has gone into the design of a new modular
synthesizer system shared by two formats- the 3U format and the 5U format. The designs are relatively new but still
retain the inherant qualities of the M3X, M5 and M5N synthesizers. The system is called the X-Series Modular Synthesizer
after the popular M3X and its protĂ©gĂ© keyboard synthesizer the X-Factor. This fully analogue keyboard is still under
serious development and there will be more information to follow on that one.
As a refreshing change from making the large scale semi modular M5 and M5N, I am now delving into the production of
smaller, free for all systems that will probably grow large! I'm taking into it all my experience of designing both large and
small analogue synthesizers as well as a few new ideas too. Please take the time to look around this website. In each
catagory there is product information, sounds, tracks and links to other related media on the internet.
Currently the 3U X-Series Dual Oscillator and 'Backend' Filter Combo are in production. I expect delivery of the
Dual Oscillator within the next two weeks- shortly after that the 'Backend' Filter Combo will roll out of production.
Please contact any of the Distributers listed to get your modules.
I intend to produce a short run of the 5U modules soon, so once again- stay tuned for that...
...anyway! I have uploaded quite a few demo sounds on here- maybe not to everyones taste- but at least they make
you think of what these modules could do in the right hands, i.e. you!
- after all- I'm an engineer, not a muscian as such!...Well you decide!
All MacBeth Products are built to exacting standards- from materials selection to the physical build.
The PCBs and Sheet Metalwork are fabricated by Zot Engineering from Musselburgh, Scotland http://www.zot.co.uk
and final assembly is performed by Diatron Assembly Systems from Norwich, England http://www.diatron.co.uk
Both companies also manufacture equipment for the medical, military and aerospace sectors of industrial engineering
312 12 Applications to Make Your Facebook Page More Engaging
Currently, there are more than three million active Facebook Pages on the top ranked site, with the typical Page boasting an average of less than 1,000 fans â oops, I mean âlikesâ (seriously, that just doesnât roll off your tongue quite the same way). Standing out from the static requires you to dress up your Page and make it more interesting and fun for your âlikersâ. Thatâs where Facebook applications come in. Theyâre basically like plugins for your Page and there are tens of thousands of them available. Deciding what apps youâd like to incorporate depends on how youâd like to engage with your peeps (thatâs an even better word than âlikersâ).
Hereâs a compilation of some must have applications for any Page. Theyâre great additions to the the basic layout that Facebook provides and they can be used in interesting ways to move your âlikesâ into action.
301 Yamaha CS-15 mods: info and modification description (contribution by Don Solaris)
The original CS-15 is a great monophonic synth from the late 70's. It has a specific dual 12 dB multimode filter structure and a dual signal path. However these two filters are permanently set into parallel connection. This can be sometimes limiting, specially when more filter power is required (i.e. 24 dB response). One of the mods here will provide your CS-15 with serial filter connection - the 24dB mode. Of course, switch is included so that you can always bring back the original unmodified parallel filter routing the 12dB + 12 dB mode.
One of the features that make CS-15 specific (next to parallel filters) is the ultra fast LFO that will go all the way up to 100 Hz. There are no many analog synths with LFOs that can go that fast (most end at 10-15 Hz). The potentiometer is used to tune from 0.1 Hz to 100 Hz. If you look at the numbers, this is quite a big range, and we said majority of LFO modulations are performed in up to 10 Hz range. The same is applied on CS-15's LFO potentiometer. That means, you can precisely tune from 0.1 Hz to 10 Hz (over 80% of potentiometer's turn ).
However, going from 30 Hz to 100 Hz occupies only 10% of the potentiometer's turn. So if you were to perform some kind FM or Ring Mod effects, this might become a tricky job, as it requires precise tuning, but instead potentiometer jumps from i.e. 20 Hz into 40, then 70 then 100 Hz. Please note, this doesn't have anything to do with potentiometer's condition (cleaning). No matter how good you clean it, the same problem will exist, simply because this is the physical precision limit of the potentiometer. The only solution is to expand the precision in the high frequency range. In other words, we will expand 10% of potentiometer's turn into some 80% or more. Switch is included to provide the original unmodified version.
