The better the resolution an image the better the finished result.
We can use a scanned image, which we would prefer to scan ourselves.
Sacnned images or low res pictures will limit the size it can blown up to without having a lot of 'noise' or pixilation.
Photos can be made in various anodised aluminium colours, glass or even mirrors.
If making them in glass or acylic, they can be used as a table centre piece, framed or the acrylic can be mounted with stand offs to some aluminium for a coloured background.
A different coloured background on glass will give you a different effect.
We can even make coasters from glass or aluminium. Great for weddings or gifts!
