Help with lighting for informal portraits

Hi All,
Tomorrow, I am picking up a set of studio lights. I am borrowing them.
Not sure exactly what they are, to be honest, but I do know there are 2 of them, and they have softboxes which are about 20in square. They are on stands. I believe they have cables to trigger them from the camera hotshoe...
I have NEVER used anything like this before, and I am going to take portraits of dads and kids at a saturday club I go to with my daughter.
I will have the use of a room which is about 12 x 8 ft with windows with blinds at one end. I can put some sort of backdrop up.
Question...based on this (poor, I know) description, what sort of set up would you use?
I have a canon 400d, 18-55 kit lens, or a number of manual focus lenses (e.g. 28mm, 30mm, 35mm, 50mm f1.8), and either hand held or a tripod.
Or, could you give me some ppointers on other ways to approach this?
The dads and kids know I am new, and so are not expecting miracles, but I would like to get a few nice shots of them.
Cheers

    There's a crap ton of videos on youtube and videojug about how to setup studio lighting. Mastering lighting takes most photographers years, so while it's not realistic to pick it up in a forum post or two, there are a few things you can do to help make things easier on you and hopefully yield some good results.

    1) Learn flat lighting quickly. While it may not be as dramatic as other types of lighting, it's safe and predictable.
    2) Shoot on a tripod. If everything else is a bit of a variable, at least be consistent. Get a test subject to pose for you and then lock in your tripod settings so that all you have to do is raise and lower for height compensation.
    3) Not sure how large your groups are so take the old photo rule of f/8 and forget it. Find the optimal strobe settings that will get you good exposures with your camera locked into f/8 1/125 @ ISO 200. That way if you're layering 1-2 people deep, you can still get decent/good depth of field.
    4) 1 pose. Keep it simple. If the kids are younger, have the parent seated and start with a child posed to he/she back to back. With additional kids, add them in opposite sides. Try to stagger height so that everyone's eyes are not at the same horizontal level.
    5) AF or MF lenses are a personal choice; I'm particular to AF myself but I trust my camera's AF system.

    Good luck!

    First thoughts are.........find out what kind of lights you are borrowing. Are they hot lights or strobes? If strobes, what are the power ratings? Shooting with strobes versus hot lights are two different things. Hot lights in a small room will cook your clients.

    The room seems too small for me. Also with the window at one end you may not need the lights or maybe just a little bounce and / or fill.

    Think about taking the portraits outside. perhaps in a spot shaded by a wall or trees.

    Thanks, Dan. Some good info there. There will be at most one adult (dad) and a couple of kids. They intend to get some nice shots for putting on Christmas cards, that sort of thing. Flat lighting...I'll look it up...:)


    Thanks, Sam. I know, I will find out what the lights are...a little premature asking for help without knowing what I am dealing with, eh?
    Looking at the weather here, the outdoors may not be an option...I may be able to get a different room...a school hall, perhaps. We sometimes have access to that...

    I'll check out the gear and get back...

    Cheers

    I got the lights...

    I have 2 x Prolinca 250. Can be half or full power.
    There's a couple of shoot through brollies, a couple of reflecting brollies, or a couple of softboxes.
    I can trigger one of the lights with my wireless trigger, and the other as slave...Or both a slave from the on-camera flash?
    with stands, obviously.
    And a couple or more backdrops...

    Cheers

    Hopefully someone else here with more lighting experience will chime in, but in the mean time.....................I would look at setting up a simple clean lighting setup. Going for dramatic lighting will be a ton more difficult.

    Start with the lights set at half power, in front of the subjects at say a 45% angle. Begin with one light, and just try shooting at say ISO 100 at f5.6 or f8. The shutter can be between say 1/100 to 1/250 or whatever your sync speed is.

    With only full or half power options, you won't be able to adjust the power levels very well electronically. You will need to primarily use distance to get the lighting levels where you want them. Of course you can also adjust your ISO and f stops to get the exposure you want.

    Adjust each light separately. When your happy with each try them together. Try one light at farther distance to reduce the light from one side to help show some detail.

    I would recommend you practice at home, and note down your camera settings and light positions and distance.

    With only two lights, small modifiers, tight space and no experience you don't have too many options. Since you're talking "informal" in the club I would do the following.
    • no need for backdrop - you're shooting in the club, you have to bring the surroundings in, otherwise shoot in the studio.
    • close the blinds - unless you're going to use a window light, which can be tricky for a group shot and rarely look informal.
    • Set one light as a rim/hair (behind/above the subjects). Probably a softbox without diffuser panels. I don't think you have a grid for it, but if you do - use it. In any case make sure it doesn spill the light into your lens, otherwise you'll end up with a lot of flaring/pollution. Probably minus half a stop from the main.
    • Use the other one (main) in full power to bounce of the ceiling in front of the subjects. I would use a brollybox located next/above the camera.
    • Make sure both lights are in a diagonal/cross fire mode, i.e. on the same straight line passing through the subjects.
    • Gelling them to 1/2CTO could be a good idea if you want to incorporate incadescent ambient lights, but again, you may not have those, so just make sure you overpower any ambient with your strobes (3 stops are typically enough).
    • And yes, use a tripod...:-)

    BTW, what is 1/2CTO?

    CTO = "Color Temperature Orange" = an orange gel filter.

    1/2 CTO = 1/2 density of the "full" CTO.
    There are also 1/4 CTO, 3/4 CTO and "full" CTO.

    Thank you. And no, I don't think I have one. :)

    I just played with the lights. They have a modelling light and the flash I had the triggering from wireless trigger, and one on slave. I also had an OCF behind the model. Used shoot through brollies first, then changed one for a reflecting brolly. Had them about 45 degrees either side, but one 1/2 distance to subject (the reflecting one)

    I think the results looked ok...this is the one with both brollies on shoot-through...

    what do you guys think?

    I'm going to set up on Saturday morning - I'll have aboiut 1hr before they'll be wanting a few shots, so time to set up in the actual room then. Just wanted to be sure I knew HOW to set up. eek7.gif

    Take the advice Nikolai gave on using diagonal lighting. That way the second light can work as a hair/fill light. That's a heck of a situation to be in. If you have time, check out the strobist's website and read up quickly. He does a lot of chimping and you may find yourself in the same boat. If you read up there, at least you'll have some idea of how to get the results you're looking for (in terms of balancing your lighting and quickly).

    EDIT: Make sure to move your subject off of your backdrop... I have to remind myself every time.

    Thank you. I will try it...just so long as I have space eek7.gif

    You know, I am just wondering if they would let me use the hall at the school where I will be shooting instead of the small room, There'd be more space for that set up, and to bring the subjects off the backdrop...

    I think it was f11. I was using a manual lens, so the exif doesn't show, but I am sure it was about that. I was shooting at about 70mm. ISO 100, 1/200s. I was having trouble with the shutter lagging, black band on photos, so it had to be 1/200.

    OK, here is what I see..............the image is underexposed and way flat.

    You shouldn't need f11 so try using f8 with lights being set up with the same distance and power. See if that helps.

    Since I don't know the distance I don't know whether you should try moving the lights closer or using full power and maybe moving the lights back.

    I would do my best to listen to Nikolai, he has a lot more experience with portrait lighting than I do.

    Also I don't think you will be able to experiment and get the lighting set up in one hour.

    Give up sleep and start working on the light set up. Keep notes on each setup and image.

    Thanks Sam.
    The Big problem is I don't have anywhere TO practice, other than our cluttered dining room. That doll is on the table! I can't move things around at all, really. But unfortunately, that's not going to change anytime soon. I'm going to have to go in and, as you said, follow the great advice I have been given, actually on the day. I'm making diagrams to take with me of the set ups advised.

    One day, I'll have my own space :)

    Well, it went ok. Now for the postmortem...

    camera 6ft away from subject. reflector umbrella above, right about 30degrees of axis. Softbox (20") behind to left, low down - diagonal to first light. Was suggested I try this set up, and tried my best.

    Camera at ISO 100, 1/200s, f10.

    Background too close to subject, but nothing I could do. Could have ironed it, though!

    OK, here is my take.

    The white balance is off. Looks a little green to me. A little hot on the face skin. Also I would try and ether include more of the arms / hands or crop them out. As it is they are just chopped off.

    Why f10? This might just be my quirk, but I would try f11 or f8. I would look at raising the camera up a little. It's hard with two subjects that are very different in height. Basically I try to shoot portraits with the camera even or slightly higher than the head, but not shooting up. Watch for Nikolai's advice on this.

    I should have had a picture of a white card to help with that, but I forgot. :(
    I used the WB in Photoshop from the white on the cushion...maybe it's not quite white?

    I will try raising the camera some more...

    F10 because I dialed it in as I was looking for a decent exposure...I have f11 on other shots, so I think this is just an anomaly.

    The "hot" on the face...is that due to the main light at 20 degrees camera right? It was with reflector umbrella, on full power (either half or full available,nothing else). Should I knock that down to 1/2 power and adjust settings on the camera for exposure?

    I am also looking for a white, plain background for tomorrow...I think that will look better than the one I used. The one today looks a little "school photo" to me, but it's all I had.

    Cheers for the advice. And I will re-read Nikolai's words again...:)

    • Uhm, when I said "diagonal" I meant position, not altitude. I thought I suggested both lights to be above the subject, plus main to be bounced from the ceiling. I'm sorry if it was unclear. Horror/Rim (as oposed to Hair/Rim) is rarely used for a general portraiture, it's more like a special effect setup.
    • F/10 (or f/11) - is a bit too much for a portrait. I rarely shoot above f/5.6 (only when I go really close). However if 6 ft to the subject was all your had...headscratch.gif Man, did you have to go to that club at all, especially since you brought a backdrop? You probably have more space in your (or their) living room...
    • And yes, bg was too close and wrinkled, esp for for F10, which of course, brought it perfectly in focus :-(
    • You also had a lot of light spill on the b/g from the second light. Ther reason I suggested to put a softbox w/o diffusers on the back was exactly to avoid such an effect. Yet, of course, you would have to have some space on the back (which is why I suggested to ditch the backdrop in the first place)
    • Exposure-wise: both subjects are very fair skinned; you need to dial your settings down.
    • Pose-wise: while both subjects look OK if it were an individual picture, as a group, esp. dad/son portrait you have missed it ne_nau.gif. There is pretty much no connection between them, they even look into different directions. Putting a son on dad's laps would be a better setting.
    • Vantage: when shooting sitting subjects upper-body it's generally advantageous to have your camera above subjects eye level. Again, putting the kid on dad's laps would equalize the height difference and you'd have less trouble composing.
    • Colors: too many msmatches: two colors on bg, cover, pillow (at least it matches dad's clothes), boy's shirt ne_nau.gif
    This reminds me of my first paid gig 5-6 years ago... I had only one light...eek7.gif Boy, I made soooooo many mistakes :hide Yet I managed to deliver a 20x30 which they were happy about and which is hanging in their family room above the mantelpiece...

    Hmmm, so I missed quite a few bits then?
    Yes, I missed the bit about both lights been above the subject. I missed the "bounced from ceiling" too. My fault for not reading your information again and again.
    The backdrop was nearly on the wall, there was no more space behind, so even if I ditched it, I would have had no extra space. There was also a lot of "stuff" on the walls, displays etc....typical of a school or childrens centre (which this was).
    I do need the advice on posing...I realised I knew nothing today. I will address that issue better next time.
    I had NO control over the clothing...they were there for the other things in the Dad's and Kid's club. The photos were extra. The backdrop and covers for the seats were my fault - I had nothing else. Next time I am going to take just a plain white background.

    When you say "softbox without diffusers"...what do you mean? Sorry if that's a real amateur question, but I am really new to this. You mean, just have the white diffuser on the front, but no backing to the softbox? The light spills out of the sides?

    Thanks again for your advice...I am really trying to understand, and it's my fault if I don't, not yours.

    Cheers

    ...

    Posing: there was a thread in People recently with the similar question I think... It's a fairly large and complicated subject (at least as complicated as lighting, if not worse), but there were a few links...
    I would have descriped primary posing rules as three captial C-s:
    • Connections
      amongst subjects and between subject(s) and environment
    • Construction
      lines and curves that construct the whole image and provide the stability, dynamics and the flow
    • Closures
      purely geometrical, "rubber stamp" black and white areas
    but it would take a much, much longer post to elaborate on the exact meaning of each...ne_nau.gif


    Softbox: yes, I meant to remove all the white fabric. Good softboxes have two layers. Entry level have one. You need none, since it's exactly the fabric that is reason of spill. Grid/crate would help, but you have none...ne_nau.gif

    So, no sides, just a front white diffuser held in place by the rods that hold the softbox. Light coming out of the sides? headscratch.gif

    That's exaclty the piece you want to remove (in case it's removable). If not - forget the softbox and use reflective umbrella, but try to focus it to the best of your abilities.
    To "focus": set it next to your bg firing accross the frame (i.e. paraller to bg) a take several test shots, each time marking the position of the shaft and checking the cone of light on the bg. You need the narrowest one.
    Again - remember not to bring it to close to your frame to avoid flare/pollution. It would help to place it higher and angling down, too.

    Sorry...silly questions perhaps. :)

    The front does come off...so light is more directed, less scattered?

    Thanks again.
