Your photographs are obscured in light of the fact that your camera couldn’t precisely concentrate regarding the matter. There can be a few purposes behind this – either there was inadequate light for the camera’s auto focus, or a similar low light circumstance enhanced any camera shake coming about because of you attempting to take a picture in lacking light, without the steadying impact of a tripod.
Then again, in case you’re shooting quick moving subjects, the shutter speed you’re utilizing might be excessively moderate and you have to change to burst (continuous) mode, or, if lighting is actually the issue, utilize auto flash, or knock up the camera’s ISO light sensitivity settings to ISO1600 or above to fix the issue.
If you were focusing manually through the viewfinder, perhaps the camera’s dioptric adjustment wheel needs adjusting to provide a clear image via which you can determine accurate focus in the first place. Most digital cameras presently additionally give an extended segment of the picture on the back LCD screen when you’re attempting to manual focus – further supporting precision and keeping away from blur.
If the problem is because you’re shooting a subject very far away with a very long zoom lens, then make sure the camera’s and/or the lens’ built in image stabilization option is activated to minimise any blur. Furthermore, once more, utilize a tripod!
