![]() ![]() Add some pressure and it holds even more. If water is cooled it can hold even more CO 2. ![]() There's lots of it floating around in the oceans right now. As it floats around in our atmosphere it naturally dissolves in water. The gas in soda is CO 2 (yes, the climate change gas). How does the gas get into the soda in the first place? You would likely have to bump up the exposure value. The reverse would be true if you are using a lighter backdrop. For the images here I brought down the exposure value between -0.3EV to -1.7EV. As such, you may need to adjust the exposure compensation by stopping it down. It will try to lighten the image making your subject look overexposed. The dark background will effect your camera's attempt to properly expose the shot. Because of this I used a larger aperture setting than the f/8 recommended above. This provided me with 1 stacked image and 8 separate shots from the sequence that I could choose from if I needed to. To help guarantee better sharpness throughout the image I used the focus stacking feature built into the E-M1 Mark II. An aperture of f/8 should be adequate for most subjects. With your shutter speed and aperture in mind, adjust your light source and/or ISO in order to maintain those settings. All macro lenses have notoriously shallow depths of field. As well, I was using a macro lens at close distances, so I also needed to be aware of how much depth of field I was achieving. I have found that I can go as slow as 1/60s with good results. Since the bubbles will move, you will need to be aware of your shutter speed. For all of these photos I used my Olympus OMD E-M1 Mark II and the m.Zuiko 60mm f/2.8 macro lens attached to my Manfrotto tripod. With a bit of practice and patience you can create some very cool images. They will constantly coat the glass so have that spatula ready to wipe them away in between almost every shot.īecause of these challenges, and perhaps some others that you will encounter, be prepared for a number of failed shots. The bubbles that you are trying so hard to capture can also be a pain in the.For the cherries shot above, I used a small clip to help hold them in place. You can also wedge a piece of foam into the container and use toothpicks to help hold your subject. However for some I skewered the fruit with a toothpick or piece of wire to help control its position. For many of these shots I just held my subject by hand. This means that your subject will probably move around a bit unless you can stabilize it. ![]()
