What to do ?.... hitch a ride !
Taken with EF 18 -250 is plus home made "acromat"

I think the highlight effect of lighting for various sized light sources is answered by those actual examples on those tomatoes with gradually increasing softbox sizes, except the first bare flash is not diffused.

Absolutely ! thanks

Thanks scitch BTW, it is definitely not true that all rays come perpendicularly out of a light emitter. If that were the case, we would not be able to see the entire sun. In Rusty's diagram, we would only be able to see that portion of the sun whose light struck our eyes and the rest would not be vi...

@ Dave The way i understand it is that all rays transmitted from a subject will do so at a right angle from the surface of the body The reason why the suns rays are parallel is because of its size in relation to us the curvature of the suns surface is so gentle that the rays are very close to parall...

Thanks Andrew......will take me a while to digest all that info

@ DaveW....Thanks for the informative links and info!

It is evident that when controlling specular highlights the main factor is the size of the diffuser , a big hurdle for me whilst chasing shiny critters in dense vegetation

Rik wrote Well, this part is clearly not correct. When the light rays are parallel to each other, the situation is equivalent to having the light come from a small source far away. If the subject is a curved mirror, then the camera will receive no light except from spots on the subject that happen t...

While experimenting with my home-made diffuser , photographing a crumpled foil ball , soon realized that no matter how diffused the light source is there are always some parts that are blown The diffuser was a flat reflector ( at +-20 degrees to the flash head) to spread the flash hot spot and then ...

Thanks Tesselator...appreciated
@ Ken ...Thanks , I am always struggling with exposure when the color is predominantly yellow , binned about 10 shots of the same crabber !

Thanks guys!

Finally decided to pop out of the lurking cabinet (i have been enjoying the site for months!)
