I use Adobe Illustrator in which to draw. When using effects such as blurring, I've noticed significantly better results when scaling up the image to the maximum size of the art board. However, the trade off is that the scale-up usually consumes a lot of memory, inflates the file size and slows down the drawing process. Where possible, I try to use more economic alternatives such as gradients but sometimes only the blur effect will do the job. Does anyone know of a way in the programme to make the blur effect more efficient when scaling up?
