It can be hard to achieve super sharp images because there are many things that can affect how the photo turns out. Digital cameras today certainly give us plenty of help when it comes to sharp pictures, and imaging software can also be a bonus in post production. Most importantly, the key to sharp images is eliminating the causes of what can make an image disappointing.

It is actually some of the basics of photography that we as humans get wrong that has the biggest affect on sharpness – rarely can we lay the blame on the camera. Poor focussing has a big impact on clarity, and quite often shifting from automatic to manual focus can eliminate this.
Movement also has a big influence on how sharp an image is, whether it is the subject moving or camera shake caused by something as simple as pushing the shutter button. This is particularly noticeable in macro photography, where getting close to a subject such as flowers can be ruined by the slightest movement.
There are a number of ways you can help to achieve the best possible sharpness in an image. Some are obvious, others not so.
Clean your equipment: Sometimes you can be doing everything right but the images just aren’t coming out as you hoped. Try cleaning the camera lense and keep it free of smudges and dust for a better result.
Use a good lens: For those of you with a digital SLR, this can make a big difference. Good quality lenses can set you back a fair few dollars, but there is a reason they cost that much. Quite often the images they produce is vastly improved to the standard lenses that come with your camera, so if you are really serious about your photography, look at investing in the best quality you can afford.
Image stabilisation: Many good lenses come with an image stabilisation system that go a long way to eliminating camera shake. They may not get rid of it altogether, but image stabilisation can make a significant difference.
Use manual focus: Automatic focus is usually fine, but sometimes it just won’t centre on what’s important in the frame. This is where switching to manual focus can be good. Quite often it is just a slight tweak that’s needed.
Aperture, ISO and shutter speed: These three elements have a major bearing on how your images turn out. Automatic settings on digital cameras are fine, but switching to manual can often be the recipe you have been looking for. The best way to do this is to note down the settings that are displayed when using an automatic mode, switch to manual and move a bit either side of these settings. You may find the results are what you have been looking for.
Stay still: As explained previously, movement is probably the number one reason why images are not super sharp. So keeping as still as possible while taking the photo should be your goal. Better yet, use a tripod and also the camera’s timer to eliminate virtually all camera movement.
