Bob is right…Photoshop is a program that allows you to manipulate/improve photos.
But since you asked–Photoshop rocks!
It enables you to improve/alter colours, change backgrounds, remove people (and replace them), apply artistic layers onto photos, and SOOOOO many more things!
If you haven’t spent any time on the program, I highly recommend it.
Cheers!
Photoshop is designed for photo colour correcting and image manipulation and is the industry standard.
Its not designed for animation.
Advantages: User friendly, multi-purpose using,
Very comprehensive graphics program, excellent features,alot of tools,
Disadvantages: Need to do some experiments in order to know the useful of the tools and features…time I started to learn Adobe Photoshop, years ago. I started with Photoshop 5.5; Those days, we had to go through a lot of steps to do effects we can do now with fewer steps and less time. Adobe Photoshop goes through a lot of enhancements and improvements since then. Through the years, I’ve upgraded Photoshop, starting with version 5.5, followed by 7, and now CS2. Generally, I skip every other version as a rule of thumb
Disadvantages 2: loading interface takes quite long,cost,takes awhile to get used to features,Takes a little while to get to know the program..
What “Industry?”
For the **printing industry,** Photoshop is a vital program because it contains superior CMYK CLUT’s (color lookup tables.) Ove the years other programs like Color Studio and Corel have taken a stab at a print-ready graphic program, but their attempts have all failed in favor of Adobe because they couldn’t cut the grade for CMYK color conversion.
Traditional digital data is stored in RGB values, which equate to colored LIGHT: various levels of red, green, and blue light. Many of these colors cannot be reproduced accurately in traditional printing, CMYK, which requires four colors of ink: cyan, magenta, yellow, black.)
The reasons for this are
1) printing inks are *reflective* colors, so light is subtractive,
2) printing inks contain a certain contamination due to the process of creating the ink – a pure cyan does not reflect pure cyan, it also reflects a tiny bit of red light as well which throws off the accuracy of calculating a color,
3) the paper upon which the ink is printed is not a pure white in the way that white light is, so a great deal of luminiosity is lost,
4) a pure “black” cannot be obtained by stacking up all three colors, its more of a muddy brown, so a fourth color must be added, black, to get true blacks. This causes the inks to lay down too thick in heavy coverage areas and not tack (stick to the paper) correctly. So a formula does what’s called under color removal in heavy dark areas and substitutes it with black to insure consistent printing.
Do you think my explanation is complex? Now you understand not only the difficulty in transposing a color from RGB to CMYK for print, but also all the adjustments it must make along the way. Consider this, and also consider Photoshop maintains the full Pantone Color libraries and can also convert these to CMYK more accurately than any graphics program in existence.
**THIS** is why Photoshop excels over most other graphic programs. Most of you use it only for the web. If your application is web-only, there are other programs that offer the same and sometimes a wider range of effects and tools than offered in Photoshop, because they only deal with RGB.
GIMP is one of those programs. Photoshop After Effects and Limited Edition are two other pared-down versions of photoshop.
Disadvantages: a legal license for Photoshop is **very** expensive, and memory intensive as well if you work with high res graphics.
GIMP is open source free software.
There are so many features, tools, and brushes in Photoshop that it’s likely many users will never even use them.
