The top photo is Lockhardtia micrantha; the flower is a little less than 1/8". The camera was on the macro mode, set for close-ups! Luckily these bloom repeatedly so when I get a better camera I will be able to get better bloom photos. I have 2 other species in bud, all are OK except my L. obtusata.
I've got a couple different macro settings(tulip) on mine. I've got no frickin' clue what they mean since I don't do manuals. There's like 6 different settings like MF(tulip), AF(tulip), s(tulip), s(tulip)MF etc. I usually just toggle between them all until I can get one that focuses in on what I want.
When I used the Micro tulip setting it automatically uses the flash - reflectively whiting-out the flower, the other Macro tulip setting automatically focuses behind the flowers. I just have to wait to get a better camera, or stop buying orchids..NOT! It sucks because I have about a dozen cool Pleuro and Lepanthes species w/ teenie-tiny flowers.
You should be able to disable the flash. I usually disable it doing macro photos. On my camera theres a little lightening button that I press and then can toggle between selections like auto, on, off, slow etc.
