Smooth gradients on a large format - what nozzle size?

[Franc Kaiser]

Quick question, guys...

What airbrush nozzle size (0.XX mm) would you recommend for achieving smooth gradient effects on a large painting (say, 1 x 1 meters), i.e. for an out-of-focus background which does not have any distinctive features but just a blur of very smoothly blended colors? For example something like this:



I tried to do it with my 0.2mm Sparmax but didn't even get close to achieve it. Do I need to go for a 0.5mm? Or even a different caliber or spray gun?

Thanks for your short inputs in advance...

It can be done with what you have, just hold it back 12-18in and control its opacity and fade by how many times you make a quick sweep over the spot/line.
Though I would be likely to use this guy for that purpose.
Sprays a little more so wouldnt take as long and the quick change feature is really handy for doing all that color changing

Larger nozzle is good and a touch up gun would be useful as well but with patience you can do it with the small ones.
