Capturing water blobs at high speeds

One contest that I really look forward to every year is the Chicago flower and garden show in Navy Pier in Chicago. Looking forward this year as I have won the past 2 year for best in show. A win this year would be 3 in a row...that's if I'm lucky.

One category for this years contest is water and plants. I wanted to try a photo that shows movement, something that is not static and boring. So I went on to get some roses at a nearby store and decided to use them for my next shoot.

For this shot I used a plexiglass light table with a transluscent base so I can hit it with lights from a strobe. I set up the single rose standing in a base in the middle of the light table. I then put a strobe behind the light table and gelled it yellow, so the light table does not look all white. Underneath the light table I added another strobe and gelled it red, the light for the background will now be red gradiating to yellow for most of the background. I grabbed my speedlite and placed it on my left side where I was going to shoot. I pointed the speedlite directly into my subject. I attached my 100mm Canon f2.8 macro to my 5d mk2 and put it in a tripod. I then attached a wireless shutter release to my camera body as I am going to need one hand for pouring the water into the flower and the other hand ready for the shutter. I attached my speedlite to my camera using a sync cord. The sync cord allows me to shoot my speedlite with full features on. With my cheap wireless trigger, I can only trigger my flash without using the built in features that it has.

With my equipment set up, I then set my speedlite to hss (high speed sync). Most modern speedlites have this. It basically lets you shoot at faster shutter speeds using a flash. With the 5d mk2, the sync speed is 200th/sec...with the high speed sync enabled, you can shoot at faster speeds above your cameras usual sync speed...of course with the expense of a lower flash output. With water dropping on my shot, I need a fast sync speed to capture it perfectly. Did a couple of test shots and I was ready to go. I then adjusted my gelled background lights to my taste. I set up my shutter speed to the fastest I can, for this shot I used 1250th of a sec. and then adjusted my aperture at f14 to get the maximum depth of field without making my shot underexposed. I had to set my ISO to 500 to get the maximum fstop and speed that I can get. In shots like this, you need to shoot in full manual mode.

I then grabbed my water bottle filled with water. I then sprinkled water all over my flower and started shooting. I probably had around 30 shots and I just picked the best one from the batch. Processed it and it was all ready to go for the contest!

High speed close ups

Couple of night ago, I wanted to try out a high speed close up shots.

I had an idea in my head to take a shot of a matchstick igniting. That'll be pretty interesting!

Things that I needed were:

Tripod
70mm macro lens
Shutter release, wireless or not
A stand for the match
Matches
of course my camera

So I put a single matchstick into a stand so I can focus on it without moving. The camera is in a tripod too so it can be as steady as I want it to be. I put in my shutter release so I don't move my camera when I take the shot. Focused on the matchstick as close as I can then turned the lights off. I setup my camera to the narrowest aperture that I can get without making the shot underexposed, for this I had it at f8. ISO at 100 and speed at 500/sec.

The flame from the match is enough to be your main light, so no external lighting sources needed further for this. So I got another match to light it up, shutter release in my other hand, and BOOM! I take the shot.



When you are attempting this shot, make sure that the actual flame is far enough not to touch your lens! If it does, you might have to invest in a new one.
