1) Invest in a Good Macro Lens
A macro lens is going to allow you to get a good, close-up view of flowers that other lenses can't. A true macro lens produces an image recorded on the sensor at life-size or larger. However, be careful as great care has to be taken when focusing macro lenses since the depth of field is very limited when you're so close to the subject. Most likely, you'll want a tripod to avoid any blurriness caused by even the slightest movement of your hands.
2) Use a tripod
Getting a good close-up requires you to reduce camera shake as much as you can. Do this by using a tripod instead of trying to go handheld if you can.3) Use a remote release
Again, in the interests of reducing camera shake, invest in a remote release to fire the shutter without risking the chance of jostling the camera by pressing the shutter button.4) Change your camera settings
Though most digital cameras have a flower photography mode or setting, you may want to switch to manual and adjust your settings along these guidelines:- Go with the lowest ISO setting available, usually ISO 100 or 200
- Shoot in RAW format so that the maximum amount of picture information is stored for you to work with later
- Set White Balance to Daylight to enable easy batch editing later
- Use single shot drive mode, rather than continuous
- Use smaller apertures to maximize detail
- Use wider apertures to emphasise a sharply focused subject against a blurred background
