I must say that I am having difficulty voting for some of the indoor macro shots. I have always thought that a macro shot is one where the subject is reproduced at life size or greater. Many of the shots don't come into this category as far as I can tell. They might better be described as 'close-up' work.
We had a similar discussion during the last macro challenge. The thing is, many cameras don't have a macro mode to turn on.
If it meets the spirit of the challenge by getting close up then that's good enough for me.
The macro shots of the current challenge are indeed interesting. I have some challenge with this myself - of course. With regards to the resulting pics - is light source and overexposure a common issue with macro shots? I am new to this, trying to learn and not meaning to offend anyone. My opinion is that a lot of the pictures from the current challenge are challenged with regards to issue.
I'll consider it a macro as long it has that close-up feel to it. I am aware that not all cameras are equipped with a macro function, so I'll be pretty liberal with my votes.
I'll put more weight on the quality of the photo, rather than how many hairs I can count on that house fly's butt.
