Hi

Many thanks for all your helpful advice, appreciated.

ToxicWolf, just a bit more information if I may ask.

I agree with you to enlarge an image can get ugly hence my requirement for good control over the size.

So lets say I want to target a screen size of 1000 * 750, would I set this size before I started composing the scene or after.

Where would I set this size on the preview or render menu?

I guest what I am asking for is a simple step by step guide to setting the exported image size.

Any assistance appreciated

Thanks
