    Hello Macro lovers,

    I'm just curious as to what exactly is considered macro, I currently have some photos of water drops, I don't know if that's considered macro or not, I will definately post the photos when I get home from work. Just looking for some clarification.

    Thanks!

    Most people would consider macro to be 1:1 or greater. (Or at least close to 1:1.)

    That means that the image on the film/sensor is life size.

    Anything less than 1:1 (1:2, for example) would usually be considered 'close-up'.

    So I guess the photos I got of the water drops would be considered close up then.

    Probably... I wouldn't lose any sleep over it though.

    If it's close to 1:1, I usually would still consider it macro. I mean, if it's not obvious as hell that it's not 1:1, that's close enough to be 'macro' in my book.

    They even put Macro marking on my Sigma only because the minimum focus distance is closer than most lenses in it's class. It cant even do 1:1.

    Macro on zoom lenses is more of a marketing move than anything else and some of the lenses with that can't get even to 1:2 (half life size).

    Generally its as said above - true macro is a 1:1 ratio or greater - in other words what you get through a true macro lens when focused at its closest focusing point.


    However the water muddies a little as many things like flowers and stuff between 1:1 and 1:2 magnifications also gets thrown into the macro/closeup groupings. It just depends how strict the group you are with defines macro - some keep to the hard rule whilst others are a little more liberal - also subject matter can affect the acceptance as well - eg butterfly and dragonfly shots are often said to be macro when a full bodied shot of most is far too big for a 1:1 magnification.

    That's true - I hadn't really considered that.

    A dragonfly or butterfly is obviously bigger than the sensor, so it would be impossible to get a full-body shot at 1:1. I still think of it as macro though...

    While I generally agree with the 1:1 definition I also group photos taken from less than 1' in the same catagory.

    Unless of course we enlarge the actual sensor size itself - I wonder how big a large format sensor is?
