As always, you will have to be the judge of whether the photo meets the requirements. You will not be told whether your photo scored or not until the rally is over. You can practice by using an old BBR flag if you like and sending photo's from your smartphone to the rally e-mail address
[email protected]. Some other entrants are already doing that., you will get a response on those.
There are lots of 'How to take better pictures with your Smartphone' tutorials on the web, but they are more inclined towards the artistic side, all that you require is a good technical image; bonus item and rally flag clearly visible. It can be done, last years winner hit 60 bonuses, there was no argument with any of his photo's.
It really doesn't matter whether you are using a polaroid, a digital camera or a smartphone, understanding your equipment is key, what it can and can't do, and practice. Working it out at the first bonus is bound to lead to disappointment.
