Unfortunately, you can very often find puzzle photos on the web
which are overexposed, blurred or for any other reason not correctly photographed.
In my point of view, you don´t need an expensive camera to get good pictures.
A simple digital camera is absolutely sufficient.
Almost all of the pictures on this site are made by a cheap camera,
which I purchased on ebay for 12 Euros.
If you want to obtain some respectable pictures,
then you should take following aspects into account:
The quality of a shot is not only determined by the puzzle object,
but also by the background. The background should have a sufficient contrast
so that the puzzle can be recognised fast.
Therefore wooden puzzles should not be photographed on wooden tables.
If further image editing is required, I would recommend a dark unicoloured background.
A dark background has the advantage that there are no shadows
and the puzzle object can be clearly delimited from the background.
In case of a bright background, it is advisable to use a flash to avoid shadows.
In case you make a picture of a flat puzzle from top view,
flash light should be avoided. The only exception is dark wire puzzles.
For a better picture quality the EP-value should be varied.
