You have two options. Oil & Water OR Water Droplet.
Do one of the two.
Part I – Items You’re Gonna Need
Part II – The Process
As you can see from the photographs, the setup is quite simple. First, hold your glass container a certain height from the floor. I used to put it relatively high, about 15 inches (40 cm), because moving the photo background (in this case the green cloth) up and down is much easier than moving a tray full of water.
Make sure to shoot behind the scene images with your cell phone.
The next step is to fill the container with water. How much water depends on what kind of photo you want to obtain. You have two basic options:
1) Add a small amount of water and you will get some textures from the glass. This is because you will be focusing your camera onto the water surface and in this case, the glass will be really close to it.
2) Add approximately 2 or more inches of water and the textures from the glass tend to disappear.
Determining whether or not you want glass texture in your final picture is more an artistic decision than anything else. Experiment with both setups and discover which one fits better on your artistic view.
Now it is time to put the oil on the water. Again, you have options.
1) Oil only–If you drop the oil in the water, the bubbles will have a flat appearance.
2) Oil and Dish Soap–If you add a drop of liquid dish soap in the water you will observe that the oil circles get more relief.
3) Oil and Straw–Before I discovered the liquid dish soap trick, I used a straw to quickly and repeatedly poke an oil circle to create small air bubbles inside. You can still use this technique to mix the flat oil bubbles with the other bubbles with more relief into the same photograph.
The final step is to setup your lights. The simplest way to do this is to point your offline flash unit directly into the background, and always, try to avoid direct reflections into the camera lens.
If you put your light source at a very low angle, part of the photo will be darker than the rest. You can solve this problem by putting it at a higher angle or adding a second light on the other side but at the same low angle to create constant lighting in the entire photo.
I like to play with one light and have some dark areas in the photo, but each photo is different, and again it is just a personal artistic decision.
If you do not have an offline flash, you can also use desk lamps. You have to increase your camera ISO or shoot with a larger exposure. The only downside is that: the larger exposure the higher the risk of blurred images.
One last thing about the lights: you will probably be shooting indoors so you will probably have one or more lights on the ceiling. Turn all those lights off, especially if they are hard lights because they can cause unpleasant reflections on your oil drops.

Part III – Taking the Best Images
First, take your photos in RAW format because in some cases you will be able to go farther in the post processing without losing image quality.
If your camera has a life view function, use it. It would be helpful in focusing and composing your shots.
Always shoot in manual, with your camera on tripod. This allows you to focus once and shoot different pictures without thinking about it.
Play with depth of field. By using a wider aperture, you will get blurred and soft backgrounds. However, if you use the smallest aperture value and your drops have some relief (using the dish soap method), you will be able to get the photograph with the background reflected on each oil drop, like in the next photo:
Finally, if you have the opportunity, shoot with your camera connected to your computer. This is useful to prevent focusing errors, incorrect light exposure, improve composition, etc.
Part IV – Editing Your Creations
After capturing my photograph, I always start work in Lightroom to make the initial adjustments. For this kind of photo, I tend to add some contrast. Sometimes, I also push the clarity, and play with vibrance and saturation controls. Each photograph is different, so you should experiment to find your desired effect and final image.
When you feel like the photograph looks good, switch to Photoshop for the cleanup and the final retouches.
No matter how clean the glass container is, you should expect to do some retouching. You can use the Healing tools on Photoshop for this.
You can also retouch other details to improve the final composition. For example, you can eliminate unwanted reflections on your drops or other small bubbles.
In some cases, it can be interesting to add a texture to the final image. It does not work for every image, but sometimes it can make the difference between a boring photo and a beautiful piece of art.
Part V – Required Turn-In
You will upload 5 edited images to your blog. Each image should be your best from each object you shot photos.
Either below each or at the very bottom please describe which process you used to capture the oil & water.
Print your best 11×14 size.
Mount your best on 16×20 matt board.
