Welcome to the Assignment 8!  

You all know The Rules by now- if not, check any of the earlier assignments.

As you’ve probably noticed there’s been some discussion on the forum about using “bounce flash”.   What is it, how do you do it, and what effect does it have on your pictures?  You’re about to find out for yourselves!



The most common is kind of flash is like one above- the camera and flash are pointed right at the subject.  This is the “usual” use of flash as taken by on-board flashes of both DSLR’s and P&S’s.  (Note that this is not always a bad thing!  Direct flash is very useful for “fill flash” when outdoors.)  

Now I’ve set up Ted E. Bear on a handy box a few inches from a handy wall cause he works cheap and has lots of patience.  All these pictures are right out of the camera except for sharpening and resizing.  (Oops, got my leg in the way of that one!  Oh well!)  Also, on purpose, I put an OU Sooner visor on him to provide a shadow.  

As you can see, it’s direct, harsh, lighting with harsh shadows on the wall.



Now we’re gonna try Bounce Flash, or #2 in our diagram above.  The flash is angled upward, bounced off the ceiling, and down onto the subject.  Note that you get a soft, even, “overhead” look to the lighting.  If you have TTL (Through The Lens) flash metering, the camera and flash will work together to get a pretty good exposure.  



Big difference in the picture, huh?  And no harsh shadows on the wall!  But notice something- since the lighting is from “overhead” a shadow has showed up under the hat.  In our big-headed Mr. Bear that’s not a problem, but people wearing baseball caps or other hats might cause their face to be in shadow.

We can fix that by adding a reflector!



I just used a piece of white paper cut like above and rubber-banded it to the flash (course my flash has, and yours might, already have a built-in reflector that you can pop up).  Anyway, what happens with this rig is that most of the light is bounced, but some of it is directed straight towards the subject, (#1 and #2 in the diagram) lightening the shadows like this:



Hints for doing this assignment:
1- Use Full Auto.  The flash and camera need to talk to each other and set shutter speeds correctly, etc.  They can do it, they don’t need your help.
2- If you really want to do this “manually”, then don’t forget that you must calculate the distance from the flash to the ceiling AND from the ceiling to the subject AND also add about 2 stops for the light-loss of the ceiling.
3- Got a P&S?  Think because you don’t have one of those fancy-smancy cameras and flashes you can’t do this assignment?  Wrong!  Here’s a couple of shots I took using my Canon P&S.  The first one is a normal straight-on flash shot, the second I used a hand mirror held in front of the flash to bounce the flash up to the ceiling (don‘t cover up the flash sensor when you do this).  Not recommended, but hey, if you have the tripod and a subject that will hold still for you it works (if your camera has a powerful enough flash)!  Remember these are right out of the camera also- without any tweaking.
(Oh, and you P&S’ers don’t have to post the third shot, ok?)





Assignment 8

Your assignment is to post 3 shots of a stuffed animal, or a stuffed human, posed within 1 foot of a wall that is wearing a brimmed hat.

Shot 1= a direct flash shot.
Shot 2= a bounce flash shot.
Shot 3= a bounce flash shot with a reflector.

K for those that complete the assignment as outlined.  We can’t wait to see your pics!

Hey Doc,

For those of us without an external flash, is there any Gerry-rig's for the on board flash?

I gave this a try.  I had to adjust the color balance cuz it came out yellow with the bounce.  I did one with full auto, straight flash, one with a white paper in under the flash, and one with a mirror.  I only have the on-camera flash so I just held up the paper and mirror to the flash.  My stuffed human sat still long enough this time.  I grabbed the first brimmed hat I could find (most of her hats are princess crowns).

Sorry about getting back so late to you, been busy.

First you get some K for even trying this one!  I usually try to make the assignments so that even P&S users can do it, but even I'll admit I was really pushing it for this one.  (I did mention it was "not recommended").

Of course the first one is a nice straight-on flash, well lit, but quite flat as expected.

Then you mentioned that you used white paper "under" the flash?  If you're using a P&S (or an on-camera flash), putting white paper/cardboard under or over the flash won't help.  The idea was that IF you aimed the flash at the ceiling (or for a different effect, bounced it sideways off a wall) that the white paper would direct SOME of the light directly to the subject.  If you really did put the paper under the flash, you just 'bounced' only about 1/4 of the light to the ceiling and then to the subject, hince the darkness and off color.

As for the last mirror shot, it seems as if you didn't get the flash to bounce off the wall and down onto the subject.  If you held the mirror at a 45 degree angle the light would go straight up and light you- not her.  You'd actually need to hold the mirror at about 15-20 degree angle from flat so the light bounces FORWARD up to the ceiling and then down to her.  If enough flash would've come down, it would've (mostly) corrected the color (my test shots trying this didn't come out too well either!).  Also, as I mentioned, the on-board flash has to be pretty strong- it's not only got to go all the way up to the ceiling, but dispersed from there, and then down to your subject- quite a distance and a loss of about 2 steps under ideal conditions.  Most on-board flashes just aren't powerful enough.

But you tried it, learned something from it, and gave it the good ole college try!  Good Job!

I understand about being busy this time of year.  I've had the week off work and had some time to give this assignment a try.  I have a Canon Rebel xTi with the on-camera flash.  I didn't mean to say I held the paper directly in front of the flash, but at a shallow angle to try to bounce up what I could.  I thought it did a decent job, because of the definition in the shadows and the texture in the wall.  I guess I will have to try a no flash photo with the same lens (my 50 mm f1.Cool to compare in the same setting.

I actually thought the mirror shot had picked up some colors from the room behind it, like it bounced behind me more than to the ceiling, if that's possible?

Yep, depending on the angle you held the mirror, it sure could've bounced behind you.  You only need a slight angle up from level (with the floor) for it to work.

Have some k for trying this one.  Kids are kids- that's why I used a teddy bear!  As I mentioned, using a mirror to bounce that flash around is NOT recommended, but will work for demo purposes.

There is a difference in the lighting, but I'm thinking that you got the labels of the pictures reversed?  (She's nicely lit in the second shot, and there is a reflection of the direct flash in the door knob).

I just checked the door nob where I took the picture and there is the same reflection of it.  In front of that door is a steinless fridge and its reflecting in the door nob. 
But knowing me I could of indeed reversed the labels... that would be just like me *giggle*

Well, since my husband didn't want to pose for this assignment I had to recruit someone else.  I found Bubba and he was more than pleased to help. 

#1 - Direct flash shot



I just noticed that Bubba's hat is not on properly in this shot but I don't think it really matters for this one. I corrected the hat for the next two shots.

#2 - Bounce flash shot



#3 - Bounce flash shot with a reflector.




I really like the way the bounce flash shot with a reflector softens up the entire image. What is most noticeable is how much lighter the shadow is under the hat.  Great to know, and something to keep in mind for future use.

You got some great examples there!  K for you!  Good Job.  Bounce flash is a great thing to know about and looks a lot more "natural" when doing indoor shots.

Thanks a lot Doc.  I really enjoyed this assignment and Bubba was the perfect guy for the job, so patient and quiet.  He's definitely very cool indeed.   Smiley  Smiley

OK. I tried doing this assignment today and here is the result of my experiment. I will call this test - "El Nombre Pooh and the Nikon D70 Pop Up Flash".  Grin

1. This is El Nombre Winnie the Pooh having his photo shoot using a Nikon D70 and its built-in pop up flash. I think he likes the hat.  Grin

2. El Nombre Winnie the Pooh is very finicky so he asked me to use a gray card to make his yellow skin tone "purrfect".

3. El Nombre Winnie the Pooh with the pop up flash fired but this time an aluminum foil was attached to the flash to bounce the light to the ceiling. He got angry at me on this one. He looks a bit dark. He said I'm too close to him that's why the flash wasn't able to bounce properly. I'm about 3 feet away from him. Or maybe, the angle of the foil was not set up properly.

4. El Nombre Winnie the Pooh with the flash fired + the bounce foil + a new foil added to act as an additional reflector. Now he's smiling at me. I think he likes this much better than the direct pop up flash look.

5. And finally, here is El Nombre Winnie the Pooh posing beside the Nikon D70 with the very crudely made bounce flash attachment.

I hope you enjoyed El Nombre Pooh's photo session.

Note: The photographer learned a lot of new stuff from this assignment.  Grin

Little tough with the foil (and like cloth it tends to scatter the light around), but you did very good considering that the links to the pictures in the assignment weren't working right! 
(I fixed them.  Took me an hour cause I haven't used Flicker in years. Sign in, password problems, links now work different.  *#&$! ).

Anyway, thanks for perservering.  Nice Job!  Have a K!

Thanks, Doc. I enjoyed doing this assignment. Makes me think outside the box for the flash mods. With an SB-600 this is easy. Unfortunately, it's too expensive for me to buy one for now. LOL!

You are on a roll!  These look great and you can really tell the difference!  Great Job!  Have another K!

I do have one tiny nit, and it's a tiny one.  Your pictures are great examples, but don't forget that we have a 900X700 limit on size and while the width is ok these are just a bit tall.  No big deal, just a friendly reminder for all reading this.  Smiley

Hi Doc and thanks again for the K.  I can see the pics look big and apologise for that Sad but I don't understand why, the info on all three detail 771x800. I use ZoomBrowser to change the size of the images and my custom settings are set to 800x600. I checked on photobucket and this has the same 771x800 + when I right click on the image in the post it also shows 771x800

The only thing I did different with these three images (before I changed the size to 800x600) was to crop and re size to remove some of the space.

Ah! do you think that this is because the pics were portate and the program just looks at the first dimension (800) and scales the second dimension?

Could be.  Maybe on potentially tall pics you need to input the height and let it figure out the width?   I don't use Zoombrowser so I don't know.
