depends what equipment you have to hand and what experience you have spraying
I'm rather proud of the blackburts i have had on some of my guitars so here's the first one we did

The way to get it light in the centre is to use a nice white light of wood. Or spray it white/ bleach it in the middle
We did nothing to enhance the woodgrain. You can dye it a darker version of the colour you are finishing and sand back before the colour coats but personally, whilst i can see it enhances the figuring i feel it destroys the dive in 3D effect you get from good figuring.
This was done with rustins plastic coating but could just as easily be done with any other kind of lacquer. We sprayed it tinted black and built the burst up rather than trying to get the burst looking right in one coat
That means the burst goes from this

to this

depending on the lighting conditions
It could have been left whiter in the middle if that was a look you were going for
... but bursts are not as easy to do with spray cans, try and find a friend with a compressor if you dont have one
