All about tangents
Tangents can be both a blessing and a curse, When used as they should be as a design tool to direct the eye arount the picture they can be the differance between making a very good picture and one that is so so.
Tagents that occur accidently and not by design can become an eye catcher which attract the viewers eye from the focal point.
The artist should be aware that these unwelcome tangents can be created unintentionly, always check while you are painting for anything that creates attention grabbers that was not intended.
This mono print when being pulled transfered more Red pigment on two of the rectangles than the the others, which made them advance and they appear to be floating in the air, the solution is to desaturate red to match the other rectangles.
The solution is to de saturate the red to match the other rectangles,
The rectangles are now attached to the wall where they belong, but the rectangle on the right is attached to the frame which is a very unwelcome tangent
Solution block out most of the rectangle to make it appear that most of the rectangle is outside the picture area or remove all together,
Now the graffiti looks like it is attached to the girl
Solution change it’s hue to a lighter value colour, now compare this picture to the first and note the differance.
Avoiding Tangents
One effect that compositional tangents have on an overall composition is that they create unnecessary tension or competition between shapes. Tangents distract the viewer of the painting from the intended focus of the painting.
This is especially problematic when the tangent exists in an area that is secondary or tertiary in importance to the main area of focus. This is certainly the case with this painting.
Obviously, I want the viewers to be focusing their attention on the two characters in the painting.
1. Isolating corners
Problem when a shape completely covers any corner of the artwork, it visually isolates that corner from the rest of the painting.
Solutions lighten or darken that area so that is integrates with the rest of the picture.
2 Half Shapes
Halves When a symmetrical shape is cut in half by the edge of the painting it creates an uncomfortable, chopped-off feeling for the viewer

Solution: Bring the entire shape inside the picture plane or crop the image somewhere other than the halfway point. You will also want to avoid cropping directly at any joint of an animal or person, or at a corner of an object or structure.
3. Fused edges (object with frame)
When the edge of an object touches the edge of your painting it can link with the frame and be isolated from the picture
Solution: Crop slightly inside the object, leaving some of it up to the imagination of your viewers, or place it entirely inside the picture frame with room to spare.
4. Fused edges (object with object)
When the edges of two shapes touch, the same “crowded” sensation is felt
Solution: Overlap your objects or put some space between them.
5. Consealed edge
When the edge of one object is hidden behind another object oriented in the same direction, the two may appear strangely joined
Together, the roof and the chimney stack appear to be one.
Solution: Change your angle so the hidden edge can be seen or put some space between the two shapes
It can now be seen that the stack is on the other side of the roof.
6 Aligned Objects
When a vertical shape intersects or is directly aligned with the apex of another shape it causes a strange, unwanted symmetry.
Solution: Shift one shape or the other so there is no overlap at the apex.
7. Shared edge
When the edge of one shape aligns perfectly with the edge of a second shape, it creates an ambiguous edge for both
.
Solution: Change your vantage point to avoid overlapping edges like this.
8. Joined Objects
When distinct vertical shapes appear directly behind an object, they often appear to be growing out of that object like antlers.

Solution: Shift the background shapes to the side, out from behind the object, or change their value or colour to blend more with the background
