The iPhone has variable uses. Apart from the customary features that an iPhone is endowed with, for example, iOS 5, iCloud, A5 Processor, Better Camera compatibility and Display screen of 3.5 inches, there is a range of apps that can be downloaded on to the iPhone for subjects as varied as exercise, diet control and heart control and what have you. However, if you are an artist, have you ever heard of special iPhone apps for an artist?

Here are 5 iPhone apps for artists.

Colored Pencils

Colored pencils is an app designed to reproduce the effect of drawing with color pencils. It is interesting because you can replicate even the pressure applied on the lines so that they taper off towards the end. Though there is no apparent flexibility to the mark value, its transparency can easily be adjusting it. This app takes care of paper texture, and if your intention is only to draw lines; colored pencils would be your ideal choice.

That's a big question, and not one that we can answer easily. Every one you ask will, or should, have a different answer.

Art doesn't have a single defining element. It can be a painting, a sculpture, a definable something that you can see and experience, or art can be something that's a little less tangible. There are no real parameters, or are there?

To answer this question, let's look at how art is defined. According to the Oxford Dictionaries, the primary definition of art is "the expression or application of human creativity and imagination, usually in a visual form such as a painting or sculpture, creating works to be appreciated mainly for their beauty or emotional power."

With this in mind, it gives us something of a springboard into understanding the different kinds of art that we experience. How often have we heard the phrases, "A five year old could do that," "It doesn't look like anything," or "They've just got too much time on their hands?" More often than not, these are comments from those who don't have a frame of reference for other art styles.

All art forms are subject to personal taste when it comes to what we like and what we don't like. However, this personal preference depends primarily on understanding, attraction or revulsion. This is part of the experience of 'enjoying' art. The problem is that we are almost hard wired to give credence to something that appeals to us, rejecting other things that do not. This governs our perception of what is art.

The wonderful thing about art, whether you love it or hate it, it is still sparking a response. Works of art do have a message, whether it's emotional, intellectual, political or even corporate. The message is there. Our personal reaction to it is another level of interaction with the piece. Art works on many different levels, based on the artist and his or her interaction with the viewer.

If you want to measure the 'success' of a piece of art work, it would be how it inspires feelings or a connection with whoever experiences it. Does this mean there can be no good art or bad art? How do you define which is which, if you do at all? This is the hardest question, that is possibly best left for critics to debate in circles.

For the rest of us, the rules are simple. There are no right or wrong answers. To find a connection with one piece of art is a powerful thing, and that should be our gauge of what is the right art for us.

When you think of art, many people think "Mona Lisa," "Sistine Chapel," "The Scream," and other famous examples of artwork, but sometimes an artist's life can be just as interesting as their paintings.

Did you know, for example, that Michelangelo absolutely hated painting? He claimed that painting was a waste of time compared with sculpture, and had to be harassed by Pope Julius II to paint the Sistine Chapel ceiling, which became one of the world's most famous paintings. Not a bad "waste of time." Want to learn more interesting facts? Read on...
