Colour modes are used in image editors to specify the basic set of
colour combinations that an image would have. Photoshop supports
the following colour modes:
. RGB
Photoshop’s RGB Colour mode uses the RGB model, assigning an
intensity value to each pixel ranging from 0 (black) to 255 (white)
for each of the RGB (red, green, blue) components in a colour
image. For example, a bright red colour might have an R value of
246, a G value of 20, and a B value of 50. When the values of all
three components are equal, the result is a shade of neutral grey.
When the values of all components are 255, the result is pure
white; when the values are 0, the result is pure black.RGB images use
three colours, or  channels, to reproduce colours on the screen.

The three channels translate to 24 (8 bits x 3 channels) bits of colour information
per pixel.With 24-bit images, up to 16.7 million colours can be reproduced. With 48-bit images (16 bits
per channel), even more colours can be reproduced. In addition
to being the default mode for new Photoshop images, the RGB
model is used by computer monitors to display colours. This
means that when working in colour modes other than RGB, such
as CMYK, Photoshop interpolates the CMYK image to RGB for display
on-screen.
Although RGB is a standard colour model, the exact range of
colours represented can vary, depending on the application or display
device. Photoshop’s RGB Colour mode varies according to the
working space setting that you have specified in the Colour
Settings dialog box.

CMYK Colour Mode
In Photoshop’s CMYK mode, each pixel is assigned a percentage
value for each of the process inks. The lightest (highlight) colours
are assigned small percentages of process ink colours, the darker
(shadow) colours higher percentages. For example, a bright red
might contain 2% cyan, 93% magenta, 90% yellow, and 0% black. In
CMYK images, pure white is generated when all four components
have values of 0%.

A portable multimedia player (PMP) is a consumer electronics device that is capable of storing and playing digital media. In PMPs, the data is typically stored on a hard drive, microdrive or flash memory. PMPs are capable of storing  images, and even playing digital audio and video. Usually, a colour LCD or OLED screen is used as a display. Various players include the ability to record video, usually with the aid of optional accessories or cables, and audio, with an inbuilt microphone or from a line-out cable or FM tuner. Some players include readers for memory cards, which are advertised to equip players with extra storage or transferring media. Image files are usually viewed on the JPEG format and some players, like the iPod series provide compatibility to additional file formats like GIF, PNG and TIFF.More and more devices are now equipped with a touch screen as the primary or alternate input. This can be for convenience and/or aesthetic purposes.

In photoshop it is easy to create a reflection effect. This is difficult for complex objects.

Here is a simple way to create a mirror like effect. Here the effect is give to an iphone.

Step1: Cut the object properly from its background. Use the various selection tools for this. Delete the background.

Step2: Select the object layer. Duplicate layer. Using free transform, move the top portion downwards as shown.

Step3: Apply a small perspective transform if required.

Step4: Decrease the opacity of the shadow to about 50%

Step5: Add layer mask to the shadow layer.

Step6: Select the mask on the layer palette. Apply white to black gradient from top to bottom to the mask.

Step7: Apply Gaussian blur about 2 pixels (filter) to the shadow image.

Step8: Apply white to black gradient to the background

for creating the effects like in this picture:

1: Do the above steps.

2: Do skew transform to the shadow layer.

Using the smudge tool and brush tool remove the distortions and make the real feel.

Dragon NaturallySpeaking 9 is one of the most popular voice to text applications-it creates your documentes as you speak, so you can give your fingers a rest! You can even surf the Internet using voice commands. With the ability of this application to transcribe a voice file to text, it is a boon for journalists, doctors, lawyers, almost anyone out there
This application can also can read out text from documents. You can dictate into most of the Windows application from web browsers to word processors to even e-mail clients. The document creation applications supported by Dragon NaturallySpeaking 9 are Corel WordPerfect, Microsoft Word and Excel
In this version of Dragon NaturallySpeaking, you can straight away start using the application without actually training it to adjust to your voice, but this is not recommended as it could lead you to pulling your hair in despair as the recognition accuracy would not be as high as if yo uspend time training it first

HOT FEATURES, COOL CASE

Zebronics brings a temperature probe and more to the sub-2.5K bracket. The Zebronics Rage PC case is a mid tower ATX case with a temperature probe and a 220 mm intake fan for the removable side panel. The fan is lit by 5 blue colored LEDs and does a decent job of upping the style statement of the case. The fan also features a potentiometer for controlling it’s speed though noise emissions were quite low even at the highest speed

The case features 4, 5.25-inch drive bays and can house 4, 3.5-inch drives There is an exposed 3.5 bay that can hold floppy or zip drives. A round metallic power button sits under the drive openings with a smallish reset button right below it. An LCD on the front panel can show nformation like ambient temperature nside the case and hard drive activity and has a blue backlight that compliments the fan’s LEDs. You can select Centigrade or Fahrenheit scales and set custom alarm temperatures for the LCD. There are 2 USB ports on the left side of the display, and mic and headphone outs on the right

side. Zebronics has put in a pre fabricated USB header which works with most front panel pin configurations. The case can hold 7 expansion boards and has notches on the side to slide in cards with wider connectors

Build quality is good though the front panel plastic feels a bit weak. The edges inside the case are well molded to prevent njury. The black glossy finish of the case makes it look quite sleek.

The power supply included with case is rated at 550W and features a decent set of connectors. There are 4 molex connectors, a SATA power connector, a 24 pin ATX connector, a 4 pin ATX connector for AMD boards and an 8 pin ATX connector for newer Intel boards. A PCI express connector is sorely missing here. We tested the performance with a Geforce 7800 GTX, 3 hard drives, and the 12 Volt fan, and we were quite impressed. At full load the PSU provided a constant 11.98V. FOR: Large 220 mm led fan, smooth edges, LCD temperature display AGAINST: Glossy finish picks up fingerprints, no PCI express connector.

HIGH POWER AND GOOD VALUED

Having a rated output power of 550 watts the GP-PS550BP is ideal for building a power-hungry gaming rig or a system with high power requirement. The PSU features dual +12V rails to balance the load demanded by the graphics cards and peripherals. Two PCIE power connectors are provided for powering SLI or CrossFir setups. Two SATA and five Molex connectors are available for drives. Thoug enough, at least two more SATA power connectors should have been provided for RAID setups like 0+1 and 5. The unit is fitted with an 80 mm rear exhaust fan to expel the heat dissipated by components within. The side opposite the fan features a honeycomb mesh for drawing in heat generated within the case

Performance

To assess the performance of the PSU we loaded it with a 120 mm case fan, six hard drives and Nvidia GeForce 7800GTX graphics card that draws power from a PCIE power connector. Using a multi­meter we measured the voltage under idle and load conditions. Load was created by throttling the GPU by running the Doom III benchmark at the highest settings The PSU remained extremely stable with hardly any drop in voltage on the +12V rail

Verdict

The GP-PS550BP is as efficient as its counterparts by other renowned brands- a good bargain considering the price FOR: Good stability, multi-GPU support AGAINST: Few SATA power connectors
