  1. @Phil Rhodes Studies have been done on this sort of thing, particularly in the context of why children in Asia, particularly east Asia, tend to do better on tests of mathematical ability than children in the west. I'm pretty sure that I once read a study which suggested there actually was a very small biological influence on that sort of cognitive ability in the population in question, but that social pressures were vastly more influential. I can't find that study now, but there are plenty of others, and the overwhelming conclusion is that it's overwhelmingly cultural. That is to say, Chi
  2. I see We’ve reached this point in the conversation: 1. Discrimination is wrong. 2. I Recognize Discrimination. 3. I know it unfairly effects certain people. But Let’s Not Make any Changes cause: 1.We Need to Study the Problem. (Cause I need Time To Deny I Recognize Discrimination.) 2. They aren’t applying for jobs. (I want to blame the Problem on those effected, to help me with my Denial.) 3. It Positive Discrimination (What I mean is, I don’t want the system to change, cause I benefit from the system.) If you can’t change the world, Change Your Actio
  3. I’m currently read “Lighting for Digital Video and Television” 4th Edition. Book states 15 amp Edison plug 110v you can use a 1200w light. 20amp Edison plug 120v you can use a 2k. Lights only, you can’t plug anything else in. Hope this Helps or leads to better answers Good Luck
  4. Dedolight 2015 Competition, someone submitted a tutorial video. Good luck with the project. link:
  5. @Mark Kenfield before HMI and LED lights how did you handle the mix color of tungsten and daylight? Off Topic I'm going to try your mobile umbrella book light contraption, with my tota lights! Tota output 750watts. Looks like you used westcott 7ft umbrella with a 2k. Any other tips to avoid melting, the umbrella? All safety tips are appreciated!!
  6. @Joshua Cadmium Have you used the Dichroic Glass Filters? Reviews seem to be mixed.
  7. I created a post "Help with Photometric". The Answers in that post and my needs/wants ruled out Aputure Lights.
  8. Update: In large open room with plenty of daylight, my plan is to use and manipulate the natural light, by using reflectors to light the subject. Depending on the look, I might use a tungsten/daylight balanced dedolight as a hair/kicker light, bounced fill from a reflector under camera position, etc. Currently using a Tota light in 40x40 softbox as key light. In room(s), with closed curtains. By adding dedolights, I looking to go from a 1 light setup to 3 light setup. I also like the precision focusing of the dedolight for still life photography. They've been on my wish list for yea
  9. @David Mullen ASC This is a small one person crew, I'm only looking to light one person for Interviews or Short Narratives Shots. If a Daylight Conversion filter is used, I know I'll lose one stop of light. The Dedolights are just for Fill, Hair/Background and Kicker light. I should still have plenty of light to work with. I'm using bounce light, when dealing with rooms that have lots on natural light. Unless I'm confused, these are 120v lights, I shouldn't have issues with blowing fuses. Are my thoughts on how this works wrong? Larry
  10. Hey, I want to purchase a set Dedolights DLH4 along with some Lightstream Reflectors. I like the versatility of these lights, wanted to know from industry professionals if Tungsten lights are on the way out, in favor of Bi-Color LED lights? Silly question are Tungsten Bulbs on the way out? Energy Department Prolong Lives of Incandescent Light Bulbs. If so do you think a replacement Bulb will take its place? Larry
  11. @Satsuki Murashige Well again, I wouldn't use any interview light at 2' from the subject and wouldn't recommend that you base your calculations on that, as it's just not a realistic working distance for most interviews. You might want to check the photometric tables for those lights at 6' and see if they'll still work for you. Thank You for the reference images. I going to check the photometric data, and do a little more research. Again Thank You.
  12. @Gabriel Devereux "need to output at least 100 foot candles at 2ft, to be useable in any interviewing set up." I'd recommend something a little higher. With your Nikon be sure to test! I say this as when I owned (now) relatively old DSLR's anything over 200 ISO I considered too noisy. Do some tests rating your camera at different ISO's and choose one you consider acceptable. I'm just using the rule of 100 foot candles at 2ft 100 ASA as a tool for researching. Testing the ISO is a good idea! Thank You Again for your answers.
  13. Thank You @Gabriel Devereux I appreciate you taking the time to provide explain the light lost with the diffusion. That really helped me understand light output. Thank You again @Satsuki Murashige for your time and in-depth answers. No go on the Skypanel. I don't own any Lights at the moment. Using a DSLR Nikon D750, I think I can go up to 800 ASA/ISO(still researching that). I was comparing different lights, looking to see what would be a good fit. I pick a Fstop of 5.6, cause I want to avoid purchasing anything that was limited to just Fstop 2.8, better yet 100 Foot Candle.
