Unboxed the new kit over the weekend and had a few hours play time. Along with the 3 head kit I also ordered another softbox and a barndoor set. I will be uploading some pics soon of both the setup and the actual subject, but I'm away on business now for a week or so.

The Kit

First impressions out of the bag; very nice. Build quality seemed quite good and each head has a nice rubberised finish to it giving you the impression it could take a knock or two without breaking, although I doubt it would bounce. ;)

The air damped stands were also of very good quality considering the low price. The only critacism would be that the background lighting stand (the little one) doesn't go really low and is still 18 inches high at it's lowest setting, but that's a small point.

The softboxes and umbrellas also seemed well built and pieced together without any major issue. Similarly the barndoor set is sturdy and the honeycomb insert was nice and solid. The snoot however was a little disapointing; the ring fitting is a bit of a fight to fit into the head and the cap over the small end fits metal to metal meaning it gets stuck very very easily, even with some WD40 applied. The snoot 'gels' supplied are very very thin and I imagine can get lost or creased easily. All that said, it works as it should so can't really complain!

The included backdrop isn't that bad actually. I expected it to be mega dire but it's more than adequate if you like that kind of thing. I've already got white and black muslin backdrops so I was able to test most shooting setups.

Shooting

By this stage I'm suitably impressed, so now for some shooting.

First off I'm shooting with the sync lead straight into the D300 and relying on the key light to trigger the sensors on the second and third units. This setup worked flawlessly for me the whole shoot, even when the trigger light wasn't pointed directly at the other heads. With that said, the cable got to be a bit of a pain when changing lighting configurations so I've now ordered a Skyport wireless set. :D

I was shooting in my dining room so had 10' by 26' feet to play with in total and by the end of the day I was glad that I had that length in order to separate the backdrop from the subject and the camera from the subject. In the end I probably used a space 10x16 for the 3 head setup. Ceiling height was just about good enough (circa 9 feet) for a classic 45/45/45 soft box shot although it was a bit of a squeeze.

For some immediate guidance I had the prophotolife.com website fired up on my laptop. I simply stepped through the video tutorials in order to put the lights through their paces. Nothing complicated but I thought this would be a good little test.

Initially when researching which set to buy I was concerned with power outputs, but I can assure you that within this sort of space that 150w is more than adequate. Most of the time I had problems with too much light and ended up shooting at f8/10 a lot of the time. I shot in manual at a s-speed of 200 to cancel out any ambient filtering through from windows and doors etc. (None of which was direct by the way).

I was blown away with the quality of the light if I'm honest. After just 30 minutes of tinkering I was getting perfectly exposed 'venture' type shots with minimal light spill. (The little bit of spill that was present was no doubt because the walls are cream coloured.) I also used the included backdrop for some more traditional portraits with 1,2 and 3 head setups. The results were equally as good. My favourite setup/result was probably the most complicated; using a key light with soft box, a big silver reflector, another softbox at the rear as a hair light and finally the third light behind the subject (my wife) down low with the snoot on to produce a circular highlight on the backdrop.

One concern I had prior to use was the potential colour temp difference between the heads when set to different power levels. Luckily I didn't experience any real notible problems. For the high key shots the background light was set quite high whilst the softbox were on relatively low power, however I was still able to find a nice overall WB setting without any unwanted tinges.

Thoughts

Overall I'm chuffed with the purchase and will be looking forward to getting them out again soon for some more shots. I will also be doing some stuff outside and will feedback my findings.

In summary:

Pros
Surprisingly good build quality
Sensors worked perfectly
Audible 'ready' beep was very useful
Additional barndoor set was great
150w more than enough power (for now)
The price. (Ordered from Karlu.com without issue)

Cons
Included snoot was a bit frustrating
Little stand didn't collapse really low
'Command Hook' background system is actually just 2 sticky hooks

TP Challenge

If I shoot with a red gel in the snoot or barndoor set then I get a red backdrop. If I shoot with a blue gel then I get a blue background. So I thought I would be able to shoot with both together and get a purple background. However, I can see the bright flash (and it is purple) but there is absolutely no visible light recorded on the camera?!? This happens with both the snoot and the barndoors and I'm just curious as to what phenomenon would cause this?

When you use a gel it doesn't colour the light, what it actually does is to filter out the complementary colour, leaving you with the colour you want (that's a simplistic answer, let's not go too deeply into physics here)
If you were to use gels of all 3 primary colours you'd filter out all the light, leaving you with nothing. Using 2 primary colours, you've filtered out most of the light, leaving you with too little to record on your shots. Of course, if your flash heads were more powerful you could compensate for this.
 
Thanks Garry, makes sense really.

I didn't think of changing the power at the time. The head was only at 1/8 so I'll give it a go next time. :thumbs:
 
I've managed to find a couple of the shots I did, but the quality is going to be very compromised because of resizing them with MS Paint! (Don't ask).

The second one has a fair bit of light spill but it's the only example I've got with me. More importantly these are straight out of the camera with no pp. Ignore any background creases or our general scruffiness, these are only test shots!

Bloody hell. I guess the third head makes up for the fact they're fairly low powered?

Lovely!

Not really, it just allows more flexibility in the composition, there is plenty of power there. The first shot wouldn't be possible with 2 heads because of the background light and hair light. The 2nd shot has soft boxes either side of us giving even lighting, with the third light off to the side fitted with barndoors over-exposing the backdrop (albeit a bit too much).

You don't NEED 3 heads (2nd shot could have used a reflector in place of one soft box) and for a lot of the time I imagine just 1 or 2 will be fine, but I like the idea of having the flexibility there.

There is going to be a learning curve definitly. Like I said, this was the first time I'd ever touched a flash head so I was quite pleased with the results.

Hmm fair enough, I've been used to using Bowens 1000W / 500W heads in our uni studio, ranging from a single head which produced this

To more complex set ups that produced this

I guess the size of your studio or 'room' or whatever it is you're shooting in, and the ambient light on top (I assume there's some?) factors into not needing much more than 150 for each head?

Soz Grant can't see you're pics because I'm at work (sssh don't tell) and they are on Flickr. I'm imagining nice one's though!

You're right with the size thing, that helped in terms of the high key shot definitly. But even in a bigger room the soft-boxes in the first shot would still be the same close distance from the subject (because we want big soft light sources) so fall-off shouldn't be a problem. The only thing that I couldn't test was how much spill from the walls was 'aiding' the shot. There was absolutely no ambient light though (dull room @ 200 f8).
 
Sounds like a decent kit for the money :)

Couple of questions...what sort of weight is the kit, is it easy to transport? Does anyone have an idea of what the minimum output would be needed to overpower sunlight (not that we get a lot of it up here), I'm guessing 150w might not be enough, but.....

Sorry to hijack your oil tanker thread, kalibre :D

Lol...

The whole kit bag probably weighs 15 kilos at a real guess so portability isn't really a problem but you wouldn't backpack it! The interfit Venus range is meant to be designed for lightness. Re the sunlight thing, I'm no expert but with the sync speed set to max and a really tiny aperture then even a decent amount of sunlight could be countered, paving the way for the lights. Not sure how 150w would stack up in that scenario.

If shallow depth of field is needed then I'm not sure how you'd control the flash heads as the shutter speed would be too high to sync??? ND Filter maybe?
 
Thinking about it, you'd probably want to gauze the sunlight anyway to make it softer and block some out.
 
If push comes to shove I can use my D70s, it will work with PWS at down to 1/1000...think I'll go and pester the staff at Calumet this afternoon :lol:
 
What a wonderful review, thank you for taking the time to post this.

As it so happens, I am "thinking" about getting a kit like that; the price does seem spot on. Would you mind posting a link as to where you go that.

Again, thank you :)
 
Great, thanks
 
oh forgot to mention that warehouseexpress.com will price match Karlu, so assuming that both sites have stock (which they didn't when I ordered) then you'll get 125% of the difference off of the WE price. That would make them around £342.50 before delivery.
 
Great, thank you for that tip :thumbs:
 
This is just what the doctor ordered! I'm looking to purchase a set of these and this has really helped to inform my decision, thanks!
 
I had just about set my mind to a lencarta kit! Now the interfit 3 head kit is back in play, wex have it on sale at £299!
 
interesting..... is there any demo shots that can be seen?
 
I have the 2 head kit and agree with the OP. It really is a great kit for the money.

The biggest issue I have is not enough space to separate my subject from the background enough so have to be careful with light from the background bouncing back.

Edit- you can see some of my shots using this kit on my website www.loveyourmemories.co.uk
