Here is one of the huge shadows I got from using this set up last week. If I am shooting more from endzones I dont even notice any shadows but this shot was really noticable.

I definitely think the shots this evening were nicer

I tried it last night. I've just been through my pictures quickly, but I see NO demon eye and very little red eye, which is GREAT! The shadows that it casts on the bleachers and even in the end zone were horrendous though. It seemed like I also got some strange shadows on the faces from the face masks. Overall though, I think I like it!

I really like these, and you are soooo right about the moms. I use the same equipment and I think I'm going to try that same setup.

For some reason, I just discovered this thread. Boy, I could have used this setup last night. I measured the light at ISO 3200 - 1/25 sec @ f/2.8. It's a Christian school with a total of ten lights per side of the field and none in the endzones. I used my flash in the hot shoe mount and got some red eye I'll have to work on, but it was either that or nothing.

I think I have everything I need out in the garage! :)
Thanks Gatorboy and everyone else that chipped in their two cents worth.

I think this solution will work out best for all those dimly lit fields. My only big cost to get this setup working was the OC-E3 cord. I had read possible issues with the much less expensive OC-E2 cord and since I'm a beginner in the photography world, I didn't need any further issues concerning equipment!LOL! Now I'll have to see about obtaining a suitable flash bracket for above the camera as well now that I have the cord. Who knows...maybe I'll even go wireless one day and actually reach the advanced-novice status too....:rolleyes:

Not to threadjack, but I tried this for the first time Friday night. I love the faces, but HATE the shadows. :confused: My setup was Nikon D50 on monopod. I had a SB-800 mounted to my light stand->hotshoe adapter (for adjustable angle beyond just the SB800). I then zip tied the adapter to my monopod with a sock sandwiched between the adapter and monopod for protection. I triggered my SB-800 via an ebay trigger and custom sync cord. The SB-800 was 15-18" below the lens.

Here are some from Friday night...

QB #7 "I got it" after fumbling the snap

Immediately following... QB #7 "I don't got it" as #51 rolls over the ball. (they didn't recover and turned over the fumble)

Unlucky #7 again losing a snap and turning the ball over.

I'm not understanding how the flash below the camera gives better results.

sorry, I didn't see the first page of this thread.

As to questions regarding flash use, I've never, ever, in any sport, whether indoors or out, been hassled about using flash.

I find when using flash below as opposed to on camera..I just don't get severe redeye or demon eye.

I've been using ETTL but am thinking of trying manual maybe at 1/8 or 1/16? As I understand(:rolleyes:) this will tend to add a smaller amount of "fill light"?
OT kinda..my HS soccer tends to be to much flash reflecting off their face/skin when up close...maybe for football it would tend to reduce the shadows?? Any thoughts to all this..:)

sly,

If done correctly, IMO, the flash should be the dominant light for your shots. In fact, for ETTL to work properly, flash needs to be at least one stop over ambient (at least 2/3 flash and 1/3 ambient).

This is because of several things. First of all, you don't have to worry about odd colors from the lights cycling or vapor lights - flash is the light color. Second, you're able to stop the action with the flash duration, and not the shutter, thereby generating decent motion stoppage - flash duration is 1/800s and faster, depending on the power setting for the flash. Thirdly, you need to have the flash be at least one stop brighter than ambient to avoid a phenomenon known as "ghosting" which occurs when you get a viable exposure from the flash AND the shutter all in the same frame.

Shooting the flash in manual is certainly a reasonable alternative. In my experience, it's a little harder to manage, but it still can produce great results.

Thanks Dennis! well..in that case I should leave it on ETTL. Is there any adjustments neede or checked to increase flash/duration? Guess I should just set shutter speed to 1/250 and the flash will produce the 1/800 or equivalent.

sly,

There are several ways to do this, ranging from very easy to not-so-easy.


  1. Choose f/2.8, ISO 800 and 1/250s, with FEC at +1 in ETTL. Shoot a few shots. Look at your histogram. Change FEC as required. This is how I normally start my shooting.
  2. Set your camera up as in (1) and take a few test shots without the flash on. If you can still make out details in the players on the field (what you want is for the players to look like shadow forms), decrease your ISO (by doing this, you're further underexposing for ambient, which is a good thing). then turn your flash on and adjust the flash output via FEC amount, again checking your histogram.
  3. Using a handheld light meter, measure the ambient light. Choose an exposure value 1-2 stops below this level for your camera, and then add flash until your histograms look good.


For all those thinking about using HSS and increasing your shutter speed this way, let me past something from a post of a couple weeks ago.

I've experiemted with HSS and prefer "normal" sync speed for the following reasons:
Recycle time is much better
Flash power is substantially higher
Batteries last longer

To remind folks, if you expose for flash properly, your flash duration should be doing the "action freezing" , not the shutter speed, so you're getting the benefit of 1/800s action stopping (the duration of a 580EX at full power - at reduced power the duration is even less) AND all the things listed above.

HSS is not a solution for night action photography. From an emitted power standpoint, for example, if the flash has a Guide Number of 190 with normal camera sync speed, if you were to employ HSS mode, at say 1/500th of a second and 1/4 or 1/8th power, the flash's GN is reduced to single digits. This is not good.

In addition, and somewhat ironically, HSS can actually reduce your ability to freeze action. In HSS mode flash, the flash unit emits pulses of light over a longer period of time in order to approxmiate a longer-duration burst of light. In other words the flash tries to emit the equivalent amount of light energy as what would be emitted by a regular flash, but does so by emitting a series of longer, lower intensity bursts.

The flash burst under HSS is not as short in duration as regular flash sync, so you can’t freeze motion as effectively, even with high shutter speeds. The mode is called high-speed sync since it allows shutter synchronization with higher shutter speeds, not that it allows one to take high-speed photographs.

HSS has its place, but for the most part is useful for shooting with fill flash outdoors with large apertures (like outdoor portraits). Under normal conditions you wouldn't be able to shoot outdoors and use fill flash unless you stop down the lens and/or use very low ISO. In some cases, even if you do this you can't get appropriate exposure because the ambient light is just too bright. HSS provides a method to still have the flash function in these conditions.


Have fun, and post your results!

Dennis

I am shooting with a flash tonight that from others on the board is down on my monopod but in front not to the side of my pod.

Should be interesting :) Never done it before so looks like I will be breaking my cherry tonight (yeah corny I know)
