Thanks for all your replies. It's tough to add details to this as I lack the terminology to describe what I'm after. Since posting this thread I have discovered that from flash to flash the difference is negligible but what matters most is what flashbulb is being used (In most cases Xenon). I'm...

Really interesting. Thanks for the details Petrochemist. I'm still amazed how this type of info is not readily available.

Trying to do a small science experiment with light but I can't find any info on the wavelengths of Speedlights. I would have thought Nikon or Canon or any of these others would put this info out there somewhere. Surely?

I'm trying desperately to find as much technical detail I can about the output of flashes such as Speedlights. Information such as the watts and wavelength data would be ideal. Anyone know a source I could go to for this info? Greatly appreciated.

Thank you for your input, I took your advice on the inverse high pass technique and coupled it with some other minor tweaks and I think I have come up with a good output. Opinions...:thumbs::thumbsdown::shrug: Before: After:

and if a re-shoot is not possible? There's got to be a good way to go about this....

I need to remove the creases in the bed linen here... the main problem area being the corner of the bed... tried some spot healing and cloning but it just ended up looking tatty... if anyone could give me some tips for a better technique to disguise these creases, it would be greatly...
