Fun with Colours: flashes, gels, mirrors.

The things some people do in their bedrooms in private! In preparation for tomorrow’s hands-on flash course I outfitted some flashes with coloured gels tonight. 

I used Honlphoto gels, seen bottom right here in a double wrap:

20161015-mw5d1420-1024

I had three flashes mounted on a stand that uses one radio trigger (like a Pocketwizard) to fire all three flashes (thus saving two radio triggers). I have discussed this three-way mount here before. I also used grids (also Honlphoto) to get three separate light circles.

As said, where all three flashes mix, you get white. After you get the ratios right, that is: the gels take light (also discussed here in a recent post) and you may need to turn one or two of them up to compensate.

Once you are done, you get white. You see it here in the centre:

And here:

20161015-mw5d1449-1024

TIP: To get the ratio right, you look at the RGB histogram. The peaks for red, blue and green need to be at the same distance from the edges.

Looking at the flashes you see the three colours I chose:

20161015-mw5d1450-1024

Red, Green and Blue. Surprise, surprise!

You see, when these colours mix, that once you get the ratios right, you get white overall. But when only two of them mix you get “in between” colours, which include cyan, yellow, and magenta:

20161015-mw5d1421-1024

So now you know why you see RGB and CYMK (where “K” means “Black”) as two alternate ways to mix several basic colours!

I also had unrelated flash fun, of course. f/32:

And my spinning top:

20161015-mw5d1389-1024

On a concave mirror, that is:

20161015-mw5d1400-1024

The moral of this post?

You should have fun with your photography, and explore, and try out different things. How many of you have gels, and how many of you have used these to mix light in different ways? That’s how you learn about light. So for those of you not coming to tomorrow’s course: go have fun, And sign up for the one after the next one: tomorrow and next week are full up, but 6 November still has a few spots open.

Any way you do it: learn about light, and have fun.

Lightroom Bug with Sierra

If you have upgraded your Mac to Sierra, the new OS, Lightroom may show a bit of a bug in the Import module.

When trying to import, you see this dialog:

screen-shot-2016-10-12-at-12-34-21

A few things are missing there, aren’t they? “File Renaming” and in particular, the essential “Destination” dialog is missing.

The solution? For now, until the bug is fixed, just right-click on one of the two that do show, File Handling or Apply During Import:

screen-shot-2016-10-12-at-12-34-52

…and then click on the two missing dialogs, “File Renaming” and “Destination” to activate them, so a tick mark appears next to them too.

You now see all four again, and you can set your destination as always:

screen-shot-2016-10-12-at-12-35-10

So although this little bug is annoying, it is easy to bypass.

Now to celebrate, here is Mau Mau, surrounded by (and lit by) two flashes:

20161012-mw5d1272-1200

Taken at 100 ISO, 1/200 sec, and f/22, with the flashes set to 1/16 power, using a Yongnuo YN622C-TX on the camera and a YN622C connected to each one of the the flashes.

 

Mistakes are how we learn…

….and I can make them too. Today is an example.

I just bought a used Canon ST-E3-RT wireless flash control transmitter. A great piece of engineering. And also a good piece of business, for Canon. And also a mistake, for me.
20161011-1dx_1235-1200 20161011-1dx_1236-1200 20161011-1dx_1237-1200

Because as I told the seller, “This one does radio as well as IR, IIRC”.

If I had only looked that up instead of relying on my recollection! Because no, it does not do light/infrared control. It only does radio control. Meaning I can control 600EX flashes, but not the six 580EX and 430EX flashes that I own. My only 600EX is faulty and needs an expensive repair or replacement.

So I have a controller that is a marvellous piece of engineering, but it only controls 600EX flashes that I do not own. Review some time when I do own 600EX flashes!

And careful when you rely on recollection. “IIRC” (if I recall correctly) implies that you might be wrong. Which I was.

Why is this flash, as I put it, a great business move? Because it forces photographers like me to buy only new 600EX flashes, and yo discard their 430EX and 580EX flashes. Which would be fine if it was one flash… but I have six of them!

Moral of the story? Check things before you trust your recollection; every time you say “IIRC”, realize you could be wrong.

(PS: Anyone looking for an ST-E3-RT? 🙂 )

 

Near London? Come see me 6 Oct 2016

Do you live west of Toronto? Anywhere near London, Ontario?

Then see www.londoncameraclub.ca – you can hear me talk about flash tomorrow night (or tonight, depending on when you read this), Thursday Oct 6, 2016. Come hear some advanced tips and tricks and come meet me. 7:30pm; $10 charge for non-members of the club.

Also keep in mind, 23 October, another small (5 people max, some spaces left) hands-on Flash workshop. See the meetup.com web site.

Now back to my presentation.No rest for the wicked. 

In Real Life

..In real life, you only have so much time when shooting an event. So you need to be quick, and you need to really master a bunch of little things.

Take this picture, taken with a wide angle 16-35mm lens at 800 ISO, 1/40 sec, f/4, with bounce flash aimed behind me. . Attentive readers may recognize the Willems 400/40/4 formula in that, modified slightly (800 ISO instead of 400) because it was so non-reflective.

20160916-1dx_0486-1024-2

Nice, but why are the verticals tilted inwards toward each other at the top?

Because the photographer was aiming the camera upward! That results in this tilt.

If the camera had been pointing downward, you would have seen this instead:

20160916-1dx_0486-1024-3

And it is only if the photographer aims the camera straight ahead, parallel to the horizon, that we get the proper picture:

20160916-1dx_0486-1024

And now a little secret: that one, the third, was in fact the actual photo taken by the photographer, Because the photographer, and that was me, knows to hold the camera parallel to the horizon. Check the verticals before you click!

So how did I create the other versions? Simple, by using TRANSFORM in Lightroom. And just like I can make a good picture bad, I can make a bad picture good.

So why not just shoot as you like and fix them all later? Mainly because this takes that most valuable of all commodities, time.

So. Last question. Flash you say. Really? How do I know this isn’t just ambient light?

Well, let’s take one with the flash OFF. Here we go:

20160916-1dx_0491-1024

Now, we could have used ambient like this but just increase the exposure by three stops. That is true (higher ISO, lower f-number, and/or slower shutter). But then two things would happen: a) you would notice the drawbacks of those actions (e.g. more motion blur, less depth of field, more grain), and b) the picture would lose its magic. You would get this:

20160916-1dx_0491-1024-2

Well, de gustibus non est disputandum, but I prefer mine:

20160916-1dx_0486-1024

Isn’t this “creative” stuff fun?
