Remove the lens hood or use an external flash. :)

If you're using a zoom lens, you will have to zoom in.

External will solve your problem regardless.

yes, having the light source higher will allow for a better light spread. Just think of it as science. A lower light angle will have more chances of being blocked, e.g. by a large lens diameter (be it hood or lens diameter)

the diagram didn't work out...

This problem occurs when the lens or lens + lens hood combination is too long and blocks the light path from the built-in flash.

You may work around it by two ways. Limit the length of the lens or lens+hood or use external flash.

Think about it, there is no easy solution. The lens is blocking the light from the flash. The only way is to frame your photo differently (by zooming in). Hotshot flashes are also positioned higher, so they have less of a problem with this too.

Your lens is probably in the path of your built-in flash. Using an external flash will eliminate the problem.

so what prime lens are you using? prime can be as small as 50mm F1.8, or can be as big as 300mm or 600mm primes.

posting the photo with the "lens shadow" will be easier for others to find out the real problem.

boh pian.

built in flash will cast shadow easily when you use wider angles because of the location.

even diffusing it will not help.

sorry, won't that just cast the shadow... on a different part of photo....
well, he isn't wrong.

except that i don't think we have such intense gravity that our pop up flash light cast a shadow cos of gravity, and if we invert the camera, the pop up flash will project a light source that bounce to the floor and back on the person.

lol... i never know much physics beyond a level..

anyways, i have tried it before with my 10-20 at 10mm, turn any way also will have shadow cast.. :bsmilie:
