A noob here. Currently, I am doing a project on high speed photography. I need intense lighting to take picture at in terms of 0.1-0.2 million fps. Problem is that I am just those handheld flash like Metz 60 CT4 and Metz 30 BCT 4. I am unable to provide sufficient light to get enough details. I have tried placing my Metz 30 right in front of the target but it is still not enough. The thing is that because I am handling at very high speed, my target is in a small chamber, only Metz 30 can fit inside. Metz 60 is used to provide light from outside into the chamber itself from a tempered glass protection. From my vendor for the high speed camera, he recommend Bowen studio light flashes to be placed outside the chamber. I understand that flashes are graded by guide number but does the greater guide number meeans the light intensity is greater?
Just wondering if there is any other more powerful flashes or strobe lights. Also, can anyone of you recommend me the store to visit to know about them? I need to get quotations for those equipments so that my lab can buy them. BTW, I need to know where got sell flash bulbs and replace them for Metz flashes.
Thanks for your attention
