-It helps that the glasses were tall, but it has to do with the angle I take them. I try to get as level as possible with my food, meaning that I don’t do too many overhead shots. Also you could try to shot from a lower angle. I am sure that will make anything look tall.
-Yes, all the pictures were taken with the 50mm lens except the very first two.
-My recommendation for almost any kind of photography is the 50mm lens. It is such a great lens for the price, Many photographers call it the miracle lens. I would recommend any prime lens for food photography, like the 85mm f/1.8 or the 30mm macro lens. They are, however, more expensive but the results are very good too.
-For my picture editing I only use Photoshop. It’s such a powerful tool and I am getting comfortable with it. If you are looking for an open source software I recommend GIMP. It is also very powerful and not too complicated.

Thanks a lot for stopping by!

You don’t need to get a SLR. My suggestions about the zoom apply also to point and shoots. Just zoom in and step back a a couple of feet. That for me worked great when I was shooting with a p&s
