TIP 10/10: Domes are ROUND!

And here is the final post in this series of 10 TIPS!

Sketching Tip #10: Domes are ROUND!

This may seem rather obvious, but I see so many sketchers draw domes as sort of flattened out the shapes in which the "edges" are drawn as if they were sharp corners instead of rounded.

Domes are essentially a stack of ellipses, each ellipse sharing a common centerline. Take a look at this diagram of the round Radcliffe Camera done in my workshop in Oxford, England last year:

You'll notice that this building, similar to a dome, is a stack of ellipses in perspective.
All the ellipses are centered on one line in the middle that also connects the
very top of the dome with the center of the footprint of the building on the ground.  
You'll also notice that each ellipse gets FLATTER the closer it is to your eye level line.

Understanding this concept points out why the diagram of the flattened dome with "corners" is incorrect, and the rounded dome edge below works much better!

Domes don't have sharp corners!!

The "edges" of your dome should look more like this. They are rounded and
you can see the shape of the ellipse starting to curve behind the building.

And here is the completed sketch! You can see and feel the roundedness of the forms, especially by looking at the rounded "edges".

These same concepts apply to any rounded form. Take a look at this sketch of a building near Piccadilly Circus in London...

I hope you have enjoyed and learned a bit from these 10 blog posts! I will continue to post tips and more sketches, so please sign up to receive these posts by email using the sign up on the bar on the right.

And if you want to learn in person, I'll be teaching workshops next year in Spain and Italy...and more places too! 
I also have two online classes at Craftsy.com and a book you can find anywhere, 
The Urban Sketching Handbook: Understanding Perspective.

Thank you so much for your interest, and Happy Sketching!
Remember, don't fear perspective!!
