hellhole 16 Posted April 7, 2016 hey guys, i am trying to add a snoot setup. i have a rx100mk2 recsea with 2 x z240 and a separate focus light. I can attached the snoot to either one of the strobe or on the focus light. which one should i go for? what are the advantages and disadvantages of having it on either system? of course the shutter speed will be much lower on the focus light. i can make do with that as the subject will most likely be not moving.

diverdoug1 56 Posted April 7, 2016 You would need a VERY powerful focus light to be useful shooting through a snoot. I DO use the modeling light on my strobe as an aiming tool for the strobe. Share this post Link to post Share on other sites

diverdoug1 56 Posted April 7, 2016 Not even close IMHO. You would be very limited by the low output. I would suggest comparing both. Share this post Link to post Share on other sites

errbrr 72 Posted April 8, 2016 How slow does your shutter speed have to be to see your focus light in the image? Can you achieve a black background at that shutter speed? Share this post Link to post Share on other sites
hellhole 16 Posted April 8, 2016 How slow does your shutter speed have to be to see your focus light in the image? Can you achieve a black background at that shutter speed? I did try on anothet set up of 300lumen. Shutter speed was around 1/30 with f9 and iso100. I still trying to see what pro and con I have. Other then shutter speed...

diverdoug1 56 Posted April 9, 2016 The main CON is that you will always be shooting within a very narrow (and in some situations non-existent) exposure range which will have your subject adequately exposed, while giving you a very dark underexposure outside of your area of illumination. It may work ok in very low ambient light conditions, but you will certainly be limiting yourself in conditions where the ambient light is brighter. Share this post Link to post Share on other sites

Sorry.. Is it possible to 'dumb' it down a little From what I can understand... With any strobe or light, it does not really matter if you have Low ambient light condition as you light source (strobe /light) is compensating that part of it. But for snoot... We want a black background with the light source only concentrate on the small point of the subject. Ie. Nudi's rhinophores or gills. Share this post Link to post Share on other sites
diverdoug1 56 Posted April 10, 2016 Don't consider it needing to be "dumbed down" , we all started somewhere . To get the dark background, you need the brightness of the snoot light to overwhelm the ambient light conditions, so that when your camera is set up to properly expose your subject, the background looks very dark. In conditions where the ambient light is bright, the snoot output must be very powerful. Share this post Link to post Share on other sites

It really quite dark even with natural light source... Okay. Maybe I slight change my question. In terms of effect wise. Will the light snoot turn out very different from the strobe snoot? Is the difference the intensity of the light source on the subject? Share this post Link to post Share on other sites
diverdoug1 56 Posted April 11, 2016 Yes, the z240 will produce a much more intense cone of illumination.. "Cone of illumination" sounds like something out of a SciFi novel Share this post Link to post Share on other sites
