Paris Chris­tou makes the most of Sketch­Book Pro.

Sketch­Book Pro 7 for Win­dows and Mac of­fers a va­ri­ety of tools and op­tions de­signed specif­i­cally to help im­prove our work­flow. Along with all the amaz­ing user-friendly tools the soft­ware of­fers, the Lock Trans­parency func­tion can make your life much eas­ier. You’ll learn where to find this func­tion, how to colour your line-art and

1 Lo­cate the Lock Trans­parency func­tion

The Lock Trans­parency func­tion is lo­cated at the bot­tom right of each layer (the pad­lock icon). This func­tion en­ables you to edit any­thing you draw or paint on a layer, which can speed up your work­flow sig­nif­i­cantly. Bear in mind that when you draw or paint, it’s al­ways best to sep­a­rate your pri­mary el­e­ments on to dif­fer­ent lay­ers be­fore ap­ply­ing the Lock Trans­parency func­tion.

2 Paint an el­e­ment and lock its trans­parency

Se­lect a paint brush and paint an or­ange cir­cle on a layer. If you then en­able Lock Trans­parency on this layer, you can paint only in­side the or­ange cir­cle. This means you’ll keep your edges nice and sharp. How­ever, you won’t be able to erase the or­ange cir­cle as long as Lock Trans­parency is en­abled, be­cause this func­tion en­ables you only to add to the layer and not sub­tract from it.

3 Ren­der the painted el­e­ment

Switch to the Air­brush tool or a soft Round brush and choose a dark brown colour. Begin paint­ing around the side of the or­ange cir­cle and you’ll soon see the ef­fect of Lock Trans­parency. No­tice how ac­cu­rate the edges are: your paint stays within the painted cir­cle. This tech­nique keeps your paint­ing clean, en­abling you to fo­cus on blend­ing and colour­ing your art­work. even ren­der any el­e­ment you ei­ther draw or paint on the can­vas us­ing Lock Trans­parency. The name isn’t very help­ful: it doesn’t so much lock any­thing as mask trans­par­ent ar­eas of a layer. All you re­ally need to re­mem­ber is that when it’s ac­tive, you can only af­fect con­tent that al­ready ex­ists on the layer, not draw or paint in new ar­eas. This is a ba­sic for­mula to help you bet­ter un­der­stand this func­tion.
