YARKOR 10 Inches Artist Proportional Scale Divider Drawing Tool, Pantograph Drawing Tool Allow Architects and Artists to Transfer Different Measurements onto Paper While Keeping The Same Proportions

The divider does the job to a fair accuracy , But it is weak in strength so the accuracy is lost in measurement, also it is very expensive when one looks at the instrument

Para ampliación o reducción de imágenes. Hay que aprender a usarlo como todo y sobre todo aprender a ser muy preciso en caso de retratos

Watercolor painting is difficult enough. I paint plein air as often as possible but until I retire I will have to paint from photos - like most artists do - but hesitate to admit. I like to draw everything freehand but I have to lightly sketch everything to make sure it 'fits' before I start painting-and that takes time. This tool allows me to make sure that I have some of the important aspects of the sizes and positioning of the things in the photo correct - right away - which saves so much time. No erasing! You can adjust the tool to different proportions like 1:1.25, 1:1.5, 1:1.75, 1:2, 1:3, etc. (I'm guessing these but you get the picture). This way, depending on the size of the photo, it's accurate with the size of paper you are painting on. My initial paintings with it worked out very well. The price is very reasonabe for the end result. This is a must have for artists - get one!

And you can't stab your foot with it like with a metal one or it wont make holes in your bag or carry case. That said it might be easy to bend if not stored straight. Needs a light hand. I"m happy with it

Was way bigger than I thought it would be. Works well though.

Lo usa mi hijo para su clase de dibujo en la carrera de diseño y programación de videojuegos y dice que es muy útil.
