Spectra Light Flash Diffuser As Reflector

2009-08-20
Flash in bounce position
Instead of transparent panel, I swap with the
solid white panel.

I was out with my family in our favorite Waterfront Pizza in Foster City. I noted the ceiling is all spectra light diffuser as reflector, dark ceilingblack and light was dim. So I found the good reason to swap the transparent panel with the solid white panel so that the bounce flash light is reflected through the white panel instead of going off to the ceiling and absorbed much into the dark ceiling. The white panel is found to be effective. I may have darker pictures than ideal but some flash strength adjustment or proper post processing will do fine for the pictures. All shots were done with Tamron 28-75mm f/2.8 and Spectra Light Diffuser solid white panel attached to Pentax AF540 flash.

I am quite happy in using the white panel as a reflector when the ceiling is black in color not serving well for the bounced flash. I normally prefer to use the transparent panel as it acts both as a reflector and partial light goes through it to ceiling for the diffused lighting for the subject.


Impressions & Notes:
  • I use the solid white panel when the ceiling is not appropriate for bouncing light from the flash.
  • I find the solid white panel more effective than the built in bounce card in Pentax AF540. For one it is much bigger in size and the most important enhancement is the angle that I can set in relation to the flash head.
  • I can also slide the Velcro strap up and down the flash head to make minor adjustment to the distance between the flash head and the reflector
  • I did try out the golden panel but I think I used it wrongly for indoor as shots come out too warm with a golden touch on faces in the dark. Perhaps, I would try the golden panel another time in outdoor setting for portraits.

Spectra Light Flash Diffuser on direct flash

2009-08-19
I happen to have a chance to use the Spectra Light Diffuser with my bounce flash in a direct position. I normally use my flash in a bounce position in an angle but I happen to take photos for my family in a church program at night with very tall ceiling, And I just want to try out the effectiveness of Spectra Light as a diffuser over the flash in a direct position

I actually snatch on the Velcro side way to give more diffused surface than what is shown in the picture. I need to find a spacer to align the transparent panel to center the panel over the flash head.

Results are pretty decent but I used it in the church in a good distance of 10 to 20 feet and effectively the longer distance may have already diffused the flash light. When time allows, I will try it on closer distance as in 5 to 10 feet away from objects. The first shot was taken at a closer distance to 6 feet. I used Pentax FA 77mm f/1.8 along with the spectra light diffuser for all shots in the church

The second shot above is in a good 15 to 20 feet away. The light is diffused enough so I can't really conclude how effective the Spectra light works as a diffuser. I will do more shots similar to #1 shot where the subjects are in closer distance. So far, I don't see the flash lighting that is overwhelming in the resulting shots.

The third and fourth shots are in a medium distance, roughly 8 to 12 feet away from my shooting position. It comes out quite alright to me. The shadow in #3 on the back is not as distracting as I would hope for.


Impressions & Notes
  • Though I would prefer to use the Spectra light used with a bounced flash, I find that it helps a bit as a diffuser when the flash is in a direct position
  • I need a spacer to center the transparent panel to the center of the flash head
  • When used as a diffuser, I find the shots less flashy as compared to other shots when I use my flash in a direct position aiming straight onto the subject

Spectra Light Flash Diffuser

2009-06-11
As Diffuser

Spectra Light Diffuser
In the above picture, I should have turned around the diffuser along the flash side to yield more coverage over the flash-head. Also, I should keep a bigger space in between the flash head and the diffuser. I used this position for straight on flash while the translucent panel serves as a diffuser


As Bouncer, Diffuser & Reflector
Spectra Light Diffuser
I look for a diffuser to be used with the Pentax AF540 flash. I am pretty new to using flash but I find flash a necessity to make the shot clean. I like natural looking picture and hence I long for an easy to use bouncer and diffuser. Also as an amateur to flash, I experiment on using flash bouncing light with light color wall and roof. The caveat that I found in flash bouncing is in not finding a nearby light color wall and roof. And I found this gadget with Spectra Light comes in handy. Its design and look is intuitive and easy to experiment and learn with.

I don't have in-depth experience with other diffuser such as Gary Fong Lightsphere and hence I don't quite know how it compares. But one thing is for sure, the Spectra Light is inexpensive to get as I paid roughly $15.00 in ebay. And I used it in first shooting with my niece graduation and it helps the newbie strobist in me, giving me more confidence into fill-flash with a natural looking pictures.

Golden Panel next to

Spectra Light Diffuser
Spectra Light Diffuser comes with five panels and a pocket holder:
  • The translucent panel is used for flash bounce and diffuser
  • The golden panel is used as a warming reflector. It comes with a sticky label on back that one can peel out and attach to the solid white panel.
  • The silver panel is used as an intensify reflector. It comes with a sticky label on back that one can peel out and attach to the solid white panel.
  • The two solid white panels can be used for bounce serving as a 4x4 solid panel redirecting light as a nearby wall or roof. Unlike the translucent panel, no light will go through the pane.
  • Depending on your choices, I learn from Russel to attach the gold label to one side of the solid white panel and attach the silver label to the 2nd solid white panel. In that arrangement, I can have an alternate white panel to go with a colored panel in silver and gold color. Sweet arrangement for multiple strobes.
And I kind of like the design in the ball-head that allow me to move the panel quite freely in the vertical and horizontally.

Spectra Light Diffuser
I have used the gadget as a diffuser and bouncer using the translucent panel in my niece graduation ceremony. So far, I am quite satisfied with the assistance that Spectra Light offers to help bounce and diffuse light from my flash. Results seems consistent as if no flash is used.

Impressions & Notes
  • A good value for $15.0 in purchase cost from ebay
  • Very effective in use in outdoor as a fill-flash bouncer and reflector.
  • I think the golden panel will serve well as a warming reflector. I have not used it to confirm as I mostly used the translucent panel
  • Indoor using the Spectra as a diffuser to cover the flash head directly and aim object straight on still has that undesired flashy look that I try to avoid. I need to experiment with lowering flash strength and flash compensation. I prefer the indirect approach bouncing light from the panel tilted at an angle instead.
  • I am experiment strapping the diffuser Velcro strap on lens and use the diffuser for the built-in flash. It may work but I am yet to test it
  • Lightweight
  • Easy to adjust angle for bouncing flash.
  • Partial light reflected from translucent panel helps in reflection.
  • With the golden and silver reflector, I expect adjustment needed for the flash strength to one's liking.
  • I buy it from this store called discountbulbs in ebay for $14.56 plus shipping

    and they seem to run out at the current moment.
