A grungy, painterly edge effect may add amazing drama to your photo without overly changing your own image. You may add an effect that looks like the photo was painted on, leaving painted edges on the sides, or an interesting effect is one that looks like a processed film photo, having a photo border edge. This can be easily achieved with any photo-editing software or online application, or any custom canvas art company could help you achieve this effect.
Introduce a Warhol-Effect
An eye-catching effect that will make a beautiful, creative canvas is the 'Warhol-effect'. The effect consists of taking your own photo, colorizing it 4 different way, and placing it in 4 quadrants on your own canvas. This may take some graphic design and photo effect skills but it may be achieved through a photo-editing software. There's also other minor details you could add to the art making it truly closer to what Warhol did in his work, like achieving a silkscreen effect. For this, perhaps asking your canvas art printer if they can achieve this look might be easier than attempting it yourself, depending on your skill level.
Make your Photo look Old-fashioned
There are some photo-editing filters and effects you could use that could 'age' the photo.Your photo can look to look like an old black and white or sepia-tone photo from the 1940s or a Polaroid style photo effect. This effect is interesting when the subject of the photo is clearly in a modern setting.
Make a Canvas Cluster
A canvas cluster is a group of several small canvas' clustered together to form one overall part of canvas artwork. For this effect you may print three various photos on different sized canvas' and arrange them creatively on your own wall. Or, you may print 1 photo, divided into 3 canvas' (a little tricky, leave this to the canvas art printer), and again arrange them creatively on your wall. This effect is definitely a talking piece when guests come over!
