I have been asked quite a lot recently about tripods.
Do I need a tripod is the question of the week this week.
The answer is simple, if you want to do macro photography or landscape photography, then yes you need a tripod.
You do not need to spend hundreds of pounds on a tripod, you can get them for £20 from Ebay or the like and start there.
When you are out shooting water - if you want to see the movement in the water you need a longer shutter speed, this means you need something firm to rest your camera on - and if there is not an appropriately placed rock - you will need a tripod.
Star trails are the same - if this is something you would like to try - you will need a tripod.
Landscapes - when you want as much as the scene to be in focus, if you are shooting at f16+ and you are using filters - or not - use a tripod.
Using a tripod ensures that you will have a good steady camera which means a good sharp shot. If you have a shutter release cable this helps even more - also available for just a few pounds online. However if there is just one thing that you can afford to buy - treat yourself to a tripod.
