There is nothing worse than the feeling of taking the perfect photo... and later realising that it is blurry, soft or lacking clarity.
Presenting regularly to camera clubs on all things smartphone photography, it is amazing how many of us miss this number 1 tip to avoid those frustrating blurry photos.
The above video is a sample out of my new... Blurry to Tack-Sharp Photos: 4-Step System.
Your smartphone lens is very robust and can tolerate an ad-hoc wipe over with any material you have access to. Before you do, I recommend checking the lens is clear of any foreign matter that may scratch the lens.
Do: > Check the lens for any foreign matter - quite often blowing on the lens will work > Lint-free cloths are great for cleaning most of the flat surfaces you can access > A cotton bud is perfect for those difficult to access areas on and around the lens > If you have a phone cover additionally clean the inside of the cover > If you have a lens attachment, make sure to clean the front and rear lens
Do not: > Use a cleaning solution. If you feel you need to, then apply a cleaning solution onto a cloth and not directly onto the lens. > Use a tissue. This actually leaves more on the lens than it removes!
A 'big' camera technique is to clean in a circular motion from outside to the centre. This is most effective to remove fingerprints, oil, smudges, dirt, and dust on larger lens attachments.
