LOL.. yep I've done that myself hehe.
I remember my mom and dad made a candling contraption (back in the day) - essentially a wooden box that could be placed over top of a light and they cut a wee hole in the top of that box to direct the light. Around the edge of that hole they glued something soft to sit the egg on - like old towel or rubber roam or similar. Worked really well for them!
I was thinking that a similar contraption would be handy for anyone then wanting to take pictures - since it's really a pain trying to take pictures with one hand while carefully candling an egg in the other LOL>
