    I hope you guys will read here first before posting anything.

    This thread is strictly to share with one another on topics relating to CFL on:
    Technical knowledge in using CFL
    Tips and tricks
    How different brand of camera behave when using CFL
    Auto White balance issues/theories/troubleshoot
    Lights/CRI/Color temperature/full spectrum theory
    Getting good images and how you achieve it with CFL
    How different brand of fluorescents behave (heat/CRI/and etc)
    Types of CFLs
    DIY CFL, interesting stuff relating to CFL

    Please don't post things like:
    Sourcing for CFL (Please please don't do it here, you go google yourself or post your own WTB in Buy/Sell)
    Comparing with others equipments (I truly believe that different type of photography equipment has it own unique strength and weakness) If you really want to compare, please post your own thread.

    Hope everyone will find this thread useful in someways. For guys who are CFL owners/non-owners, I hope we can make use of this and learn from each others. thanks

    Hi all, just came across these two very very cool videos on "choosing lights", very well made and I have to said that is the best I have seen so far . Very detailed infos about all kinds of continuous artificial light sources from the very old tungsten to the very new "LED", they even covered on flash (very brief though) light source. Do check it out guys

    hi all, if you are looking into making yourself a DIY CFL. Than this is a good reference video. This creative guy shows step by step how he made a DIY "light bank" CFL at a low cost from ordinary household and hardware materials. Really like the part when he showed how he made a flexi reflector with just plastic board, coat hanger wires and tapes. Do check it out

    Few weeks back, I saw this ultra cool video from Fstoppers where they used an iPhone to do a fashion shoot. One of the setup, Lee Morris used a beauty dish (strobe modeling light) + other modifiers to lit a model. This inspired me to come up something similar below:



    Well... in a way, still need some improvisation. The fluorescent is a 55W bulb as I can't squeeze in my bigger 85W. Will look into it when I have more time. Coming August, I will try to do a shoot with this "CFL" beauty dish and see what I get.

    Yes , after 2 weeks+ of planning. I finally got a chance to try out the CFL beauty Dish. When my good friend pal WEE saw the beauty dish, he ask me what I call this, I told him I call it the MNM CFL beauty Dish. MNM stands for Mix and Match, basically the whole thingy is formed by using different equipments that I own. The photos from the shoot can be view here.

    Just to clarify some of the info in this thread; the 'spectrum' of a light source is effectively the wavelengths of the colour spectrum the light source outputs. A continuous spectrum light source is anything which burns (i.e. daylight - the sun, fire, tungsten). 'Continuous' refers to the fact that a light source like this would output a percentage of every colour represented in the colour spectrum.

    It's easiest to imagine it as being represented by a graph, with the colour frequency underneath. A continous spectrum light source would look like this (where RGB etc would be represented as wavelengths, measured in Nanometers - Nm):



    A discontinuous spectrum light source is generally one which tries to emulate daylight, and they're usually electronic (i.e. light bulb, flourescent tubes). These output as many colours as they can to try and appear as a continous source, but they have wavelengths of colour missing. Again, in graphical form, they would appear:



    This would represent your typical household light bulb.

    The final one is a Line-Plus continuum source, which would be your electronic flash, or a daylight-balanced bulb. This is effectively a better discontinuous source, in that it tries to represent a larger percentage of the wavelengths.



    Note how many more wavelengths are shown to fill the gaps.

    The colour temperature of a light source comes from whichever of those wavelengths is the more dominant. A fluorescent tube would show a green cast in photos, as that would be the most dominant wavelength. The human eye automatically converts this, but the camera does not (hence WB settings).

    Hope that helps.

    *Excuse the diagrams, they were knocked together very quickly in CS3. They're not intended to be accurate in terms of the colours, or the range of wavelengths.

    Recently LINCO, the maker of FLORA lights have produced numerous new videos. And two of the videos, were actually comparison of different continuous lights gear/equipments. A flash strobe was also shown in the two videos but was not tested due to obvious fact that it is not continuous...

    Light Intensity test between HMI, Halogen, LED, Fluorescent and Fluorescent Light bank

    Who's the best: HMI, Halogen, LED, Fluorescent and Fluorescent Light bank?
    Personally... I don't quite agree to the video titled "who's best", each light have its unique strength and weakness. It all come down to individual preference, budget and situation needs. However if you are a newbie who like to find out more on this topic. These are "quite" good reference videos for you to start with.

    thanks useful video
    thanks dacian.

    Anyway, here are some videos on CF Ring Light. I first saw these about two years back when it was much smaller in size, and commonly people use it to shoot small products. As time goes by. It get bigger and bigger and now people used it to shoot music video and even stills. I don't own any CFRL, so I can't share my experience with you guys. If any CS guys and gals out there do owned these big CFRL. Please do share with us your experience using these lights. I am very interested to find out will it produced something similar to the classic "diffused layers shadow" like the strobe ring flash?
