Using the Sony A7iii and Tamron 28-75mm i want to get some pictures of me and my dad on our motorbikes but as this is the first time i am attempting this, i need some guidance. The finished picture i want is us in focus with a nice soft blurred background. If you could help me select the correct mode, AF settings etc that would be great. Do i need a tripod? What about filters? It will be tomorrow lunch time so it may be bright sunshine or it may to torrential rain! Thanks.
