Testing the DIY Spinlight

Recently, we posted about a DIY alternative to the Black Foamie Thing and Spinlight 360 using a Flashright Pro.  What you see above is yet another such DIY alternative.  This one was posted on the Strobist Flickr forum by photographer David Huy.

Hit the jump to see how I assembled mine, and how it performs against the modified Flashright.

COMPONENTS
The "DIY Spinlight 360" uses the following parts:

• Flex mount flash gun adapter.  Variously branded as K-8, Interfit, and Strobies.  There is a specific adapter for the most common flashes.  For example, for the SB-800, the K-8 branded flex-mount adapter is the CA-1 model.  Available on ebay.  Some are white, some are black.  As low as $9.99
• Honeycomb grid.  This is the matching grid for the flex mount above.  To my knowledge, the grid is the same for all types of flex mount.  Available on ebay (a bit harder to search for because of the variety of names used, including honeycomb, honey-comb, and grid).  As low as $11.99.
• Optional: dome diffuser.  This is similar to the type of dome used for Gary Fong's lightsphere.  Available on ebay.  As low as $1.99.  I didn't attach a diffuser to mine.
• black foamie thing (BFT).

I removed the grid on the honeycomb grid accessory, leaving just the outer frame.  Strictly speaking, you don't have to do this, but if you leave the grid on, the grid will eat up a lot of the light.

Removing the grid is not easy.  The grid's frame is held together by three clips, equally spaced apart:

In addition, there are three tabs that fit into three corresponding holes on the other part of the frame.

To disassemble the frame, I held the lip of the frame and pushed against the edges of the honeycomb until the frame started to separate.  Before disassembling the grid, I didn't know about the tabs so I tried to pry one side open, which broke two of the tabs.

Once the frame is separated, you can remove the grid and reassemble the grid's frame.  The frame attaches to the flex mount and rotates.  All you need to do is attach the BFT to the grid, and if you wish, a dome diffuser.

The flex mount itself is mounted to the flash head just by pressure and friction.  It's reasonably secure though I wouldn't dangle my flash by holding on to the flex mount.

IMAGE QUALITY

How does the DIY Spinlight 360 compare to the Flashright modification?  To me, they have almost identical performance in terms of light pattern and efficiency.  (The DIY Spinlight 360 seems to have a slight edge in efficiency.)

One subtle difference is that when aiming the flash to the rear corner, the Flashright mod may have a slightly lower lighting ratio (i.e. shadows are a bit brighter), possibly because a portion of the dome may not be entirely blocked by the BFT.  In the Flashright shot below, note the thin hard shadow below the jaw line - meaning that a second light source (in addition to the bounce) was illuminating the subject.

OTHER DIFFERENCES

Although I haven't tested them in the field, both the DIY Spinlight 360 and the Flashright Mod appear to work very well as replacements for the BFT and Spinlight 360.  If you are choosing between the two, here are some factors to consider:

• Cost: the DIY Spinlight 360 can be had for about $21.99.  The Flashright Mod costs whatever the Flashright Pro costs (currently around $27 + shipping and handling with the 74PLEASE discount code).  I'm not sure though if the Flashright Pro discount will last.
• Versatility: the Flashright Mod can be rotated to allow the dome to contribute to the exposure.  I suspect the same is true for the DIY Spinlight if you attach the dome diffuser, but I haven't tested it, and there may be a decrease in efficiency from the diffusion effect of the dome diffuser.   On the other hand, one benefit of the DIY Spinlight is that the flex mount can be used with other accessories that are produced for the flex mount, such as a globe, mini beauty dish, mini softbox, snoot, or barn doors.
• Compatibility: the Flashright Mod can work with almost any speedlight.  The DIY Spinlight requires you to have the specific flex mount for your flash.  If you have another flash or are borrowing someone else's the flex mount might not fit.
• Weight: the DIY Spinlight (part of which is made of a dense plastic/rubber) is much heavier than the Flashright Mod.  When the DIY Spinlight is mounted, it will make the flash a bit top heavy.  Sometimes, with a little movement, the flash head might not maintain a tilted angle.
• Durability: I haven't tested the durability of either the DIY Spinlight or the Flashright Mod, but I think the DIY Spinlight would be more durable because it has a simpler design, and much of the flex mount is made of a plastic/synthetic rubber material.  It is not indestructible though -- its weakest part is likely to be the 4 small plastic clips that hold the grid frame.
• Portability: the DIY Spinlight is larger than the Flashright Mod and will take up more space in your bag.
• Speed: the DIY Spinlight is faster to attach and remove compared to the Flashright Mod.  All you need to do is push it on the flash head .  With the Flashright Mod, you need to use a velcro strap.
• Stability: the DIY Spinlight is a snug fit on my flash but can be knocked off with moderate force.  By contrast, it is hard to remove the Flashright from the speedlight without undoing the velcro strap.
• Ease of use: both the DIY Spinlight and Flashright Mod are easy to rotate, though I find the Flashright Mod slightly easier to rotate because you're turning a smallish dome compared to a wide ring with the DIY Spinlight 360.
• Ease of construction:  FWIW, I think the Flashright Mod is easier to make because pulling apart the honeycomb grid for the DIY Spinlight is not easy.  Make sure no kids are around to hear you cussing.
• Aesthetics: this is totally subjective but I think the Flashright Mod looks more sleek, elegant and high-tech than the DIY Spinlight though the rubber band (if you use one) can detract a bit from its appearance (maybe i'll use a black one).  I imagine the DIY Spinlight could look pretty cool too in black.

I will be switching between the DIY Spinlight and modified Flashright to test them both in the field, and will be updating these posts with my observations. (Note: the product shots for this post were taken with the Flashright mod.)

FlashRight Pro as Spinlight 360 Substitute (Part 1)

In this post, we'll discuss the Flashright Pro, a flash modifier by Peter Gregg, who catapulted into fame with A Better Bounce Card.  The Flashright Pro touts several features:

• lightweight, compact design
• directional: instead of sending light everywhere (such as in a dome diffuser), it sends light toward a direction 
• rotates 360 degrees
• diffuser

The Flashright Pro is intended to serve two primary functions: to direct bounced flash and to illuminate the subject with diffused light.  There is second version of the Flashright Pro, the Flashright Pro Extreme, that has a slot to accommodate 'ratio disks,' which are diffusers with varying sizes of holes.  The idea is to allow the photographer to control the proportion of light used as bounce flash and as diffused light.

The Flashright Pro was recently relaunched with a significant discount.  With its more practical price, I decided to get one, not for its original intended purpose, but as a substitute for Neil van Niekerk's black foamie thing (BFT) and the useful but expensive Spinlight 360.

FLASHRIGHT PRO COMMENTS

The first function of the Flashright Pro is great.  Bouncing flash from a specific direction rather than in all directions is a good idea, in my opinion.  Doing so will get you soft directional light, not just soft light.  Directional light is more interesting than perfectly even, soft light.  Not to mention it will save your batteries as well. 

However, I am less excited about the second function of the Flashright Pro -- sending diffused light to the subject.  Illuminating the subject using a small diffused light source is not particularly useful because as I have repeatedly demonstrated, diffusion DOES NOT soften light.  AT ALL.  See here.  That's why when I saw the Flashright Pro design, I was not the slightest bit interested.  I knew it would create hard shadows.  When I saw the $99 price, I was even less interested.

BLACK FOAMIE THING COMMENTS

My favorite modifier for on-camera flash is still Neil van Niekerk's black foamie thing.  When bouncing flash, I use either the BFT or I use my hand as a flag (to block the direct light from the flash from reaching the subject). 

The problem with the BFT is that it falls off very easily.  Recently, while shooting for a client, I couldn't count the number of times it fell off.  The BFT can't be strapped tightly to the flash either because it needs to be able to rotate around the flash freely.

The BFT has since been updated as the Spinlight 360.  The Spinlight 360 attaches to a speedlight securely, while allowing a flag to be rotated easily.  The only problem with the Spinlight 360 is the cost, which is $129 for the basic version.  Even with Neil's code for a $20 discount, it's still a very high price for a very simple piece of plastic.

Note: Neil did not create the Spinlight 360.  Someone else used the idea for Neil's BFT and turned it into the Spinlight 360.

FLASHRIGHT PRO AND BFT HYBRID

I didn't feel comfortable buying the Spinlight 360 but I really liked the idea and kept thinking of possible substitutes for it.  Then one day, I got an email talking about the relaunch of the Flashright Pro.  There was nothing different in the design as far as I could see, but one thing they changed was the price.  From $99, they dropped it to around $27 + shipping and handling.  That seemed like a very realistic price to me.  As I thought about buying one, I noticed that the Flashright Pro could function as a Spinlight 360 substitute.  The Flashright Pro's head could rotate 360 degrees just like the Spinlight.  If I attached a black foamie thing to it, it might function just like the Spinlight 360, at a far more affordable price.

[As an aside, there is a bit of irony here.  I could be wrong but I sort of recall that Neil conceived of the BFT idea from Peter Gregg's A Better Bounce Card.  So, I found it a little amusing that years later, Peter Gregg's Flashright might be repurposed as a substitute for the Spinlight 360.]

Anyway, I ordered a Flashright Pro, dreams of a cheaper Spinlight dancing in my head.  Ordering the FR was not super smooth.  I didn't get an order confirmation for several days.  And after one week, I called them up - just got voicemail.  I emailed them and it turned out that they hadn't even shipped my order.  Grrrr.  It took another few days before they shipped my order and finally, I got my order.

INITIAL OBSERVATIONS
The Flashright Pro arrived in a padded envelope, without a box or any fancy packaging.  The instructions were printed with inkjet using a very tiny font to occupy only 1/4th of an 8x11.5 page (perhaps to save ink).  I was surprised at how plain the packaging was.  I've seen cheap eBay lighting accessories with fancier packaging. :)

The Flashright Pro itself seemed to have ok build quality.  It looks much more polished than what you might expect from the very plain packaging.  I don't know how exactly to describe the plastic, but it's not the soft, dirt-cheap kind such as those used in some cheap light modifiers.  Neither is it the hard kind of plastic used in speedlights.  It's not fragile, but if dropped on a hard surface, it looks like it would crack.  (Then again, it did survive being mailed from Illinois to California without any damage.)

The Flashright Pro's components

The Flashright Pro is attached to the flash with a supplied velcro strap.  If you look at the above picture closely, you'll see that there is a piece of rubber foam where the velcro strap is attached.  This helps strap the velcro tightly around the flash.

There is only one size of Flashright, so it had to be made large enough to fit a large flash head such as that of the Canon 580EXII.  With a small flash head like that of the SB800, the Flashright is a bit off-center.  In my tests, this off-centered position did not appear to affect the efficiency of the Flashright, producing identical output either off-center or centered (using spacers that I inserted).

FLASHRIGHT PRO TESTS
I started testing the Flashright Pro by testing the light quality of several configurations:

• Flashright only, with the flash head aimed forward, while the diffuser is rotated to face upward.
• Flashright only, with the flash head tilted at around a 45 degree angle, while the diffuser is rotated to face upward.
• Flashright only, with the flash head in vertical position.
• Flashright with black foamie thing covering the opaque side of the diffuser ("FR + BFT dark").
• Flashright with black foamie thing covering the diffuser side ("FR + BFT light").
• Black foamie thing only.

I tested the different configurations by aiming them above the subject, to a corner (camera right), to a wall on camera right, and to the rear camera right corner.  All shots were on TTL.  BTW, if you're wondering how I can aim my SB-800 to the rear right corner, it's because I did the head modification.

Here are the results:

In my opinion, the result that looks best is the black foamie thing.  However, the Flashright with BFT on the opaque side appears similar, except that in the right wall shot and rear corner shot, there is a visible hard shadow cast by the diffuser dome.

The Flashright used by itself is not bad in my view, at least when the flash head is tilted so that most of the light is shielded from directly hitting the subject.  The hard shadow cast by the dome is even more visible compared to the FR with BFT, but the dome is also acting as a fill light, bringing up the shadow detail.  I would not mind using it if I didn't have the BFT with me.

I also tested the efficiency of the configurations by using manual flash.  I aimed the flash above the subject and used 1/2 power (ISO 200, f/2.8, 1/250).

I was surprised to find that the most efficient modifier was the BFT.  I was also surprised that the Flashright with BFT combination was far less efficient than the BFT.

MODIFYING THE FLASHRIGHT
I was not satisfied with using the Flashright with the BFT because it was using too much power, diffusing the flash in all directions, which is really unnecessary when bouncing flash.  After some tinkering, I found that it was pretty easy to remove the dome and the diffuser.  See the video below:


Note that the two halves of the Flashright's frame are held together by tabs.

One of the tabs (note: the small screwdriver is NOT needed to disassemble the flashright)

There are 5 tabs, and they are not evenly spaced.  There is a part where there is a larger gap between tabs.  That part corresponds to the part of the lower frame that is above where the strap is attached.  To reassemble, just align the tabs and snap the frame together.

I tested two modifications of the Flashright Pro.  The first modification I tested was to use the opaque part of the dome.

I just removed the clear dome and the diffusion disk.  With this mod, the partial dome is very loose.  To remedy this looseness, I wound a few loops of twist tie to serve as a kind of gasket between the partial dome and the FR frame.  You can see part of the twist tie in the shot above.  I then attached a BFT to the partial dome (in my case I used velcro tape).

The second modification I tested was to use the clear dome instead of the opaque partial dome.  With this mod, the dome fits the FR frame perfectly just like an unmodified FR.  I attached the BFT to the dome using an elastic band for friction and the infamous Neil van Niekerk hair band, which BFT fans will recognize.

I tested these modifications against the BFT using the same protocol I had done for the earlier tests.

I was pleased to find that both modifications produced lighting patterns that were very similar to those of the BFT.  In terms of efficiency, the BFT was still the most efficient configuration, but both modifications were not far behind from the BFT.

I was a bit surprised that the 2nd modification performed as well as it did both in terms of lighting pattern and efficiency.  I thought that the dome would act as a diffuser that would waste a lot of light.  Now that I knew that it did not have any noticeable disadvantage, I preferred the 2nd mod because it doesn't need any kind of spacer between the dome and the frame to rotate properly.  Moreover, compared to the first mod, the 2nd mod does have one advantage: if I choose to, I can partially expose the diffuser dome to lift shadows (albeit creating a hard shadow of its own).

In the shot on the left, I aimed the flash to the left, and I rotated the BFT to completely block the dome.  The result is that the shadows are very soft, because the subject is illuminated purely by bounced light (a very large light source). 

In the shot on the right, I aimed the flash at the same direction, but this time I rotated the BFT so that the dome would be partially visible to the subject.  In the result, we can see that there are two shadows: a soft shadow from bounced light, and a hard shadow from the dome (most visible below the jawline).  On the other hand, the soft part of the shadow is brighter compared to that of the first shot.

Because the 2nd mod appears to be more versatile, I've decided to keep my Flashright in that configuration.  I have yet to test either mod in real life shots, but so far, the Flashright Pro looks like a promising substitute for the Spinlight 360.  As regular readers of our blog know, we pride ourselves in real world testing of equipment.  I will indeed post real world test results in a followup to this post.
