    If you agree register your interest here
    Quite a good idea Mr Trout

    IMHO everyone beamshot should be made with the same camera settings.
    e.g. MTBR shootout settings http://www.mtbr.com/beamcomparisoncrx.aspx

    "camera settings: full manual, ISO-100, Exposure-6 seconds, Aperture-F4.0, Focus-Manual, White Balance-Daylight"

    great idea!

    emitter: MCE M bin.
    Optic: Rocket SS
    driver: 1A buckpuck in 2s2p giving 500mA per die.

    near enough standard camera settings.

    Distance to shrubs at the back is around 100 feet.

    Does anyone know how to change the exposure and whatnot on my canon SD850IS? I don't think it's possible but maybe it is...

    Here are some I took last night. F2.8, ISO200, exposure time 1 second, it just happened to use these settings, I didn't change anything.

    Here's my first creation, built per this thread:

    This forum makes me dizzy!

    Beamshot:



    I forgot to check ISO (it was 200) and WB (crap, I have to go turn on the camera). It was 6 sec @ f4.5 and the grape post is ~20 feet away w/ the fence ~45 feet.

    Triple XR-E R2 with Ledil, Carlco, and DX1920 optics compared

    This is my first build, an achesalot design using 3 x XR-E R2 WC tint, running at 1000ma using buckpuck. All shots taken using DSLR - 6 seconds, F4, ISO 100, whitebalance = daylight.

    The soccer goal is 40' away and the yucca tree is another 90' past that.

    The images are in this order:

    - control
    - comparison using MTE SSC P7 torch
    - 3 x DX 1920 optics
    - Carclo optics - 2 x ripple medium + 1 x plain tight
    - Ledil optics - 2 x CRS-M + 1 x CRS-SS


    ** Control **


    ** comparison using MTE SSC P7 torch **


    ** 3 x DX 1920 optics **


    ** Carclo optics - 2 x ripple medium + 1 x plain tight **


    ** Ledil optics - 2 x CRS-M + 1 x CRS-SS **

    Dang...I'm sorry guys...I forgot you had settings already when I went out to capture these...won't be quite the same but should be relatively close.

    My settings were: F2.8, 5 second duration (10 second delay before firing to make sure these came out clear from my point and shoot on full manual).

    Control shot (this is my back alley with just the above and the ambient light)



    This is a shot of my Planet Bike Alias 15W halogen @ 8W (this one is super circuit equipped)



    This shot is of the same light @ 15 W (SC equipped)



    Here is one more @ 15W, but this time I'm using the helmet mount wiring, no SC so it puts out a little bit more power.



    Next shots are of the new light: Deestar Altair 3x R2 Cree's, Ledil optics (1xSS, 1xD and 1xRect), bFlex...it's my first DIY and here's what it looks like:



    Beam shots: Altair @ 350mA



    Deesta Altair @ 700mA (I believe....it is the middle setting)



    Finally, the Deestar Altair @ 1A

    My little Eva. Single MCE Juiced @ 50 FT.

    Couldn't do the MTBR setting on my camera. I used ISO 100, Daylight, F5.6, 7 sec (which will be quite a bit darker than the MTBR settings despite the one second longer exposure) Included a control too ....ahh yes, look at that sad glow, living in the city

    According to this link which i just found, and really wish I had read a month or more ago here (someone who obviously knows a lot more than me about camera settings) I should have exposed my shot for 12 seconds at 5.6 to get the equivalent to the MTBR F 4 6 sec. He even has this crazy chart that explains more with a little pin wheel chart. Neat!

    If to lazy to read the link. I have summed it up, all the below are equivalent MTBR beamshot exposure levels. (all MUST STILL be done at ISO 100 and daylightl)

    F2.8 – 3 seconds
    F4 – 6 seconds
    F5.6 - 12 seconds

    F8.0 - …crap, off the chart. Should be 24 seconds (don’t use this, too long)

    Oh well, will have to update my pictures some time so they look brighter and are side by side comparable to everyone else.

    To sum up for those who have glassed over eyes after reading all this blabber mine are ~2X darker than the MTBR setting would yield

    Laters ~Chris

    Still haven't ridden with the new lights but they seem great. I'll post some pictures of the lights in the a light build thread.

    beamshots at 200 ISO?

    hi
    I have a Nikon D40. the lowest ISO setting is 200.
    could I use these settings as equivalent?
    3 seconds, F4
    6 seconds F5.6

    I would think that going from ISO 100 to 200, cutting the light by one half by either decreasing the shutter time or reducing the f stop would provide the same exposure. If not, I can't even do a "beamshot"
    thanks

    Hoping to shoot indoors tomorrow night. No luck borrowing a digital camera that's manual capable. I borrowed a light meter to stick on the wall for lux readings dead center.

    Minolta X700 (oldie but goodie) on manual mode, ISO 200 Daylight at F5.8 6 secs, my 50 mm no filter, instead of Zoom. Thanks for confirming the equivalent exposure, [B]TobyMack[/B ]!

    Is 4 feet distance is a semi-standard on Mtbr DIY light Forum for indoor beam shots?
    Standard (3/4 or 20 mm) blue masking tape crosshairs OK?
    Centimeters or inches on measuring tape?
    I assume I get the digital output from the film processor/printer on CD for posting?
    Haven't done anything like this in quite a few years, any tips?

    Hello,
    I used a X300, and made a lot of pics with a long exposure. The main problem is the reprocity failure phenomenon : Suppose the light dropping your film is like water falling in a open can : if there is only some drops of water going down, the heat will dry some water to vapor, and you need more drops to fill your can. So, with exposure time under 1s , there is no problems. On a landscape pic, if mesurment indicate a 6 s exposure, I had to shot with 3x the time, using a positive slide roll, witch is more non-linear than a negative film. Take a look at http://en.wikipedia.org/wiki/Recipro...photography%29 ; the explanation is far more "english compliant"
    You should take your pics at F4 - 3s (5s realy opened), or F2.8 - 1.5s (2s) or f2(f1.8)- 1s. Reciprocity against depth of focus...
    Good luck !
    TTGV

    Bunch a beamers. No home brews, but we all love us some beam shots.

    Shot with a 14 mm focal length lens on "full frame" SLR. ISO 1600, F 5.6, 3/4 sec.

    The players (in order of appearance):

    Control shot

    Dinotte 200L - single P4 (I think) with optic (low and high)

    Stenlight S7 Premium - Dual Rebel 100's with frosted 20 mm carclo optics, narrow and medium. (low, med, high and turbo)

    Spiderfire P7 direct driven by a single 18650, 40 mm orange peel reflector. (low and high)

    Romisen RC-T5 - Quad P4's, integrated quad reflectors, two 18650's. (low and high)

    And the star of the show, the new Dinotte 1200L+ dual quad. As in eight xpg's! (low, medium and high)

    beam shot question, improvements, thoughts:

    ISO 100, some cameras don't really do 100, more like 150 or 200,
    propose ISO 200 as a base.
    F4 and ISO 100, is 6 seconds, that's a like time, that means no handheld ether.
    and F4 is shallow. would say at least F8 , and for bright lights , maybe F16.
    F8 would also lead to sharper image, and less blowout.

    so F8 at ISO 200 , would that still be 6 sec ?
    to speed things up
    F8 at ISO 400 sec ?
    and for the 2000+ lumen lights to use
    F16 at ISO 200 sec ?

    what you think ?

    now for the tape,
    lets say every 10m a cone,
    since not everyone has cones, and want to buy some,
    how about, bier cans, or any other, should do.

    lens settings:
    the base, I'd say ~30mm , that's close to human vision
    that should cover basic perspective.
    for the spot, distance.
    we need something longer,
    lets say 100mm

    blind spot:
    now this is to show, how much glare there is,
    would think, F16 for that.
    difference, facing the light at rider height, say 5 feet of the ground or 1.5m
    from a distance of 15m and 30m .
    what you think ?

    and since you pushing those burners,
    maybe a laser temp reader, for the light head,
    and a power meter to show the actual watts burned.
    since the big LED lights, start out fast, but throttle even after a couple minutes.
    of course ambient temp needs to be measured to.
    the wind we will leave out. that get's to much.

    thinking of doing a beam-shot fest in massachusetts.
    cheers, Rob
