How do you mount photographs properly with a matt and frame?

Question

I have some enlargements which look fantastic and have had matting cut but when I put them in they don't look smooth and flat. I have been taping them to the mounting but the photos look like they are bent when the light catches the photos

Answer 1

first use acid free archival tape or photo corners to mount your photographs. I mount mostly fiber paper which absorbs moisture so I tend to leave one side untapped. This may work for you. Just make sure your photo is smooth by using your hand and you should be fine.
