Understanding the concept of ISO

By definition ISO is a measure of the camera sensor sensitivity to light. The higher the ISO setting, the more sensitive we terhada sensor light.

To get a clear picture of the ISO setting on the camera we (ASA in the case of photographic film), think about a bee community.

And if my camera set at ISO 200 means I have 200 worker bees.
An ISO is a worker bee. If I set the camera at ISO 100, it means I have 100 worker bees.
The task of each worker bees are picked light entering through the lens of the camera and make pictures. If we use the lens aperture identical and equally we set at f / 3.5, but I set the ISO at 200 while your 100 (think again about the worker bees), then the image has to be faster who completed?


When we add the ISO settings from 100 to 200 (the aperture that is always constant - we lock the aperture at f / 3.5 or through Aperture Priority mode - A or Av), we shorten the time needed to manufacture a photo on our camera sensor by half ( 2 times faster), a shutter speed of 1/125 to 1/250 sec.
You can try this sense in the case of the aperture, try to set the shutter speed at 1/125 we always constant (or through Shutter Priority modes - S or Tv), and change-change your ISO settings in multiples of 2; eg from 100 to 200 to 400 ... and so on, look at the changes in the amount of your aperture
When we add more ISO to 400, we cut the time of making photo by half again: 1/500 sec.
Whenever exposure shorten as much as half, we call raise sxposure by 1 stop.

Understanding Exposure Drafts

Often after buying a good digital slr camera and point & shoot, we are fixated on auto mode for longer periods of time. Auto mode is the most easy and fast, but it does not give satisfaction creativity.

For those who want to "pass and rising class" of the auto mode and want creative soul into the photographs produced, it helps us understand the concept of exposure. Renowned photographer, Bryan Peterson, has written a book called Understanding Exposure in which the concept of exposure are easily explained.

Peterson members illustration of three elements which must be known to understand the exposure, he was named the relationships between the three as a Triangle Photography. Each element in photography triangle is associated with light, how light enters and interacts with the camera.

These three elements are:

ISO - a measure of how sensitive the camera sensor to light
Aperture - how big open lens when the photo was taken
Shutter Speed ​​- the span of a "window" in front of the camera sensor is open
The third element of interaction is called exposure. Change in one element will result in changes in other elements.

Parable Exposure Triangle

Perhaps the easiest way to understand the exposure is to provide a parable. In this case I like the parable of the exposure triangle as well as a water faucet.

Shutter speed for me is how long we open the tap.
Aperture is how wide we open the tap.
ISO is a strong impetus from the water taps.
While the water flowing through the faucet is received light camera sensor.
Certainly not a perfect metaphor, but at least we got the basic idea. as you can see, if the exposure is the amount of water coming out of the faucet, then we can change the exposure value by changing one or a combination of all three constituent elements. You change the shutter speed, mean change how long the water tap is open. Aperture change means changing how much water flow, while changing how strong encouragement from the water source.

BIOSTAR Promotes Family of Gaming Hardware with Gaming Motherboard and VGA Combo

BIOSTAR is promoting the gaming motherboard, the Gaming Z97X along with the VGA cards that are powered by nVidia's GeForce GTX750Ti chipset as a compelling gaming hardware combo set. The motherboard comes with the new Gaming Commander Box accessory as well as cutting-edge features like USB 3.1 on-board and innovative durability enhancements. This gaming family of hardware from BIOSTAR gives you a gaming combination comprised of the best motherboard and value priced GPU for a superlative gaming experience.

BIOSTAR's GeForce GTX750Ti series of cards brings the visual horsepower needed for high-end gaming. With 2GB GDDR5, on a full size PCB with a unique dual fan cooling design, this card in combination with the Gaming Z97X motherboard is all you need. It has Dual DVI/miniHDMI output support and supports NVIDIA PuroVideo HD Technology as well as DirectX 11. It also supports NVIDIA PhyX and CUDA Technology. You will need a motherboard that has a PCI Express 3.0 x 16 bus interfaces to stick this card in. For that BIOSTAR has the Gaming Z97X.

The basis for this super combo is of course, the motherboard. BIOSTAR's Gaming Z97X mainboard ushers in the first complete gaming motherboard designed by BIOSTAR. This is something new from BIOSTAR, because it's not just a regular gaming motherboard that satisfies a typical gamers' needs by just merely offering top of the line hardware, rather it is designed from the ground up to be cool looking and high performing. Let's talk about what makes the BIOSTAR Gaming Z97X so special.

The Gaming Z97X comes with key features such as USB 3.1, three PCI Express 3.0x16 slots, PCIe M.2 support, Dual GbE LAN and BIOSTAR exclusive Hi-Fi 3D Audio technology. Two on-board HDMI supports 4K / 2K HD resolutions. There is also the introduction of the SATA Express Connector which supports both SATA and PCIe storage solutions giving maximum data transfer speed of up to 10Gb/s.

This board also heralds the launch of the BIOSTAR external Gaming Commander box. It fits in a standard 5.5" (CD-ROM) area; it is also comprised of software with voice control utility exclusively designed by BIOSTAR.

The Gaming Z97X is the first motherboard that comes with an onboard USB 3.1 connector, a new standard known as SuperSpeed +. The new standard doubles data transfer rate from 5Gbps to 10Gbps, and it's backward compatible with current USB3.0 and USB 2.0 devices.

Most of the features we've just talked about are related to system performance, how about. The Gaming Z97X adopts BIOSTAR's exclusive Hi-Fi 3D technology and an additional amplifier, it enables high definition multidimensional sound to reach extreme high quality sound. With the Gaming Commander BOX, you can freely use either the sound chips from the motherboard or the BOX in different scenarios to get the maximum sound performance.

One thing no gamer can stand is a sudden internet disconnection; therefore, BIOSTAR prepared two LAN connectors, with the most popular Killer LAN and Intel LAN chips. With Dual LAN technology, the primary advantage is doubling bandwidth from 1G to 2G, and two high-speed gigabit networks can provide super high data transmission efficiency. Another major advantage is "Load Balancing", it allows a gamer to attach both network adapters into one single network. It will therefore support the aggregation "teaming" function by merging two connections to support multiple aggregation modes. In addition, Ethernet lightning protection circuits reduce the probability of damage from lightning or other power surge, so if one connection is disabled the other will automatically kick in.

We've covered its hardware specs, high quality sound and high speed LAN, what about product stability? BIOSTAR has it all covered. Around the CPU area, there is a 12 phase power design to prevent the CPU from overheating; BIOSTAR's exclusive super-durable ferrite chokes and solid capacitors also enhance energy efficiency and extend the motherboard's lifespan. An Anti-Surge and ESD protection provide the best protection to reduce the shocks caused by ESD as well as other damages arising from overvoltage transients thus enhancing system stability and durability.

Super durable box headers provide solid, secure and durable connections between the motherboard and peripheral cables. When running such high-end machinery sometimes such tight tolerances call for some expert debugging of overclocked or highly stressed systems. For that, there will be Super Rapid Debug 3 which gives out critical POST code information on a vivid digital LED display. This greatly helps trouble-shooting of a system.

And of course, it all looks cool and sharp with the silk black "Armor design"; there are a lot more great features such as LN2 switch, T-Overclocking utility and XMP button for easy CPU and memory overclocking, and dual HDMI ports support true 4k/2k HD video.

In short, to achieve a usable gaming rig, you really need to focus on two key pieces of hardware, the motherboard, as the basis of the system, and VGA card which powers the graphics. For both of these key items BIOSTAR has gamers covered with the Gaming Z97X motherboard and nVidia GTX750Ti series cards.
