Mixed Media within deviantArt refers to artwork in the making of which more than one medium has been employed. For example, a drawing that combines color pencils, watercolors and inks in the same canvas.
To be considered as Mixed Media, an artwork needs to combine 2 or more traditional or digital mediums. However a big misconception is that Mixed Media refers only to artworks combining digital AND traditional and this is not entirely true. The combination can also be between traditional mediums only or digital mediums only and in fact, when you intend to submit to this category, you'll find that you'll have to choose between one of the following:
Traditional Mixed Media
In Traditional Art, Mixed Media involves the combination of two or more traditional techniques such as oils, pastels, watercolors, charcoal, pencils, collage, acrylics, ink, etc.
Digital Mixed Media
In Digital Art, Mixed Media involves the combination of two or more digital techniques such as digital painting, vector, vexel, 3D, photomanipulation, fractals, etc.
One of the most common situations when it's difficult to determine if an artwork should go into one category or the other it's with Photomanipulations. To read more about the differences between Photomanipulations and Digital Mixed Media click here
So, what about combining both Digital and Traditional?
As explained earlier, Mixed Media is a combination of mediums, which can be between traditional only or digital only, so what about those that combine both?
deviantArt doesn't have a gallery dedicated to these pieces that combine both digital and traditional techniques, so it's up to you to determine which one is more predominant and then choose the more appropiate category. For example, a drawing done with pencils, scanned and then added other digital elements alongside other heavy edition should go to Digital Art.
If the traditional part of the artwork is more predominant, by adding just some minor digital elements and other minor adjustments, then it should go to Traditional Art
I hope this makes it more clear about what is and what isn't Mixed Media. Stay devious! - ^Thiefoworld & ^Astralseed
