1. Try to shoot during less traffic period such as Sunday.
2. Snap highest pixels photos so that the photo remains sharp if cropping is needed.
3. Drive at the lane next to the exist lane during photo taking. JV9 was taken on the exit lane, results won't be good.
JV8 is a good example....but it will be perfect if without those long queing cars.
I understand that in real life situation, sometime it will be difficult to achieve, but just try your best.
A good clear photo, will only take 15 minutes to convert to JV, but unclear, with cars photos might take up to 1 hour to convert to JV.
