If you are using Diana F+ and would want to use film to shoot the pictures, if take note of the following details before you shoot any images.

If you are shooting in the day time, I could suggest that you use ISO100 film instead as during the Day time, it is very bright and there is no need to use high ISO film.
Please also remember to adjust to N mode!

If you are shooting in the night time, please use higher ISO film!
Do not use ISO100 film as you will regret it! No matter how bright your flash is,
the image appear is not good! I can recommend you to get ISO400, ISO600 film instead.
Please do adjust to B mode and turn it to cloudy! Please note that, it need time to load the picture and you need to be very firm!

If you shake too much, your image will be very blur and the effect is not fantasy as what you expected.

You can make the image to be slightly blur to get the limousine effect. You can see the below picture for example which is used ISO100 film!

My apology that my scanner images is not clear.
