Well, so much had been going on with my camera as I'm trying to use every day of Ramadhan before it is over and I'd be back to work then! Well, I have to say that I can be lazy at times but I think I deserve this! Here, I will be taking off from where I stopped last time, as I was experimenting with High Speed photography. After finishing with dropping a cherry into some colored water, it was time to try out a bouncing ball!


I thought about this idea after applying the "cherry" experiment. I was trying to implement my old trigger (again)  but I ended up shooting all good shots with remote cable alone and changing the method of shooting in between sessions (the experimenting took about one week or more a bit): once using LiveView, and other times without it, and also using the Mirror-Lock option.

Splashing Boom I
Canon EF 100mm Macro, f/20,
8000-1s, ISO200.
The results were majorly for splashes and droplets hanging in the air instead of the ball at the moment of bouncing, but many interesting shapes resulted with these water droplets. After my experiment with falling cherries, I've decided to increase the shutter speed to its max point (1/8000s) since that does not affect the power of the speedlites in general (the aperture does). I tried to apply another technique with sharpening when processing these images, as in Splashing Boom I and others, where I've applied sharpening to specific portions of the image only to pop out some features and make it look like a 3D image somewhat.

Splashing Boom III
Canon EF 100mm Macro, f/20,
8000-1s, ISO200
I was lucky, after many, many, many trials, to catch the moment at which the ball was bouncing of the table (which was covered with aluminum foil and sprinkled with water), while running the camera on LiveView. Many successful attempts occurred later as well and they were rotated as is the case in splashing Boom III, but with variant beauty. In fact, even with Splashing Boom III, I noticed some slight blur in water droplets and the ball even though the shutter speed was at its maximum, 1/8000s. This made me search for ways to go around this speed in some way (technical or by technique) but I'll keep that for later. The ball here in Splashing Boom III might be blurred for being slightly out of focus after all, and for this reason I've decided to boost the f-number (to increase the depth of field further) in order to increase my chances of catching the ball relatively sharp. This, of course, forced me to change the speedlites sittings (all three of them) in terms of angle at least (all were working in full power after all).

Mirrored II
Canon EF 50mm, f/22, 8000-1s, ISO200.

As trials went on, I've changed the lens to 50mm to have more space and increase the chances to catch the ball within the frame (it was a bad choice somewhat though since water splash details are not clear at that zoom level). Anyway, at this point I decided to work with Mirror-Lock option (which requires pressing the shutter button twice to shoot the photo) as I was trying to reduce the time lag. In an email sent to Ubertronix about such lag, they explained to me that such lag is usually due the camera's shutter and it would be better to connect the trigger to the speedlite; but this is not possible in my case:
Hi TJ,

The lag is from the camera not the strike finder device or cable length. If you can set up your shot with the Strike Finder firing a flash instead of your camera, the  lag will be close to 0. Let me know what you are trying to shoot and I might have some specific setup suggestions.

Check out the information concerning shutter lag of the 7d in this link The other thing you can do is partially depress the shutter release and hold it before a shot. That will cut your shutter lag from 83 ms to 61 ms based on these specs.

Please let me know if I can be of further assistance,
The Information here were kind of a surprise since working on LiveView does actually longer lagging time than working in normal mode! However, not that, and not even working with Mirror-Lock and a trigger, did time correctly with this bouncing wall, which at the end drove me to work, again, manually and by hand. I noticed that I did capture better results using the Mirror-Lock option and I got the camera within the frame more often, but probably the best of them all was Mirrored II here in which the ball was just taking off with a tiny trail of water underneath it. I will check with possibilities to work with triggering my speedlites instead of the camera later on, but that would require to work in complete darkness (and the camera shutter is kept open for a certain time). When everything failed, though, I've simply punched the table…

I tried here again to picture the splashing water, but seems the water wasn't enough, and it is a good thing that I used 50mm lens; Otherwise, my fist won't fit in the frame. And apparently my skin needs some care! Now, all these shots (lot of them not shown here) need to be sorted out again and filled with information for uploading to stock websites.

I could have gone further with this post, but I'll keep it short for now. There are other experiments I'm attending to at the moment, specially with my very old microscope with which I'm trying to shoot better and sharper images (so far images are kind of blurred). Along with the microscope experiments, I've been working on some various images ideas for our group's June project which is themed "Abstract." I might have some material to be posted by the next blog post.
Meanwhile, I couldn't keep my promise to myself for not placing an order right now, but I had to process an order for various items (and books) but I'm not in a hurry. Thus, all items were shipped for free (which takes nearly a week) and still to this very moment some items are being processed because they are not available. Some of these items are essential and I might talk a bit when this package arrives to me (which might be in July!). I consider this to be my own gift to my own self for my birthday, since no one I know around me would appreciate such gifts for me! Hopefully I'll cope with the finance later on.
As the financial situation is shaky; once up and once down, I'm still not sure about my plans to travel (and not sure where to). One thing is for sure: I need it. I need it like water and food. If only…
