Firstly, the camera determines how the various colour are rendered into black and white. You can take some control back with filters, but more glass (or plastic) in front of your sensor risks reducing the quality of the image slightly.
Secondly, You might like the image in colour as well as black and white, when you see it on a big screen. Converting images from colour to black and white is easy, but if you discard the colour data in-camera, you cannot get it back.
That's my story, and I'm sticking to it.
Question is, can you recognise the source text? Answers on a postcard....
Select some background images to work with and display one on your laptop/ipad/etc screen. The image only needs to be big enough to cover the space under your water container. It should contain some bright elements as it will be back-lighting your image. Turn the laptop screen up to max brightness.
Place the laptop, with the screen in a horizontal position, under the glass table (as close to the table top as possible without touching). Do not place water-carrying objects directly onto computer screens - unless you're keen to splash out (sic) on a new computer!
ISO: 400 or higher, to accommodate the low light produced by the screen
aperture: wide open (e.g. f2.8), again to help with the low level of light; also helps keep the background soft, so it does not dominate
shutter speed: 1/60 second; you want the shutter slow enough to allow lots of light in, but fast enough to freeze the image if the oil is still moving in the water
You might also like to add some food dye. There are a range of colours cheaply available, but I find red works best for some reason - other colours seem to 'gloop' together into one big depth-charge, rather than produce pretty patterns. Food dye can also look good on its own against a plain bright background.
Shoot immediately after adding the food dye, and fire off a number of frames in quick succession; you can then select the best pattern or create a progression of images.
If you are planning to use a printed background, you will need to think about how you want to light it. Whether you use flash or a constant light source, you want to be able to direct the light onto the background without directly lighting the water. In other words, you will create back lighting, which will bring out the contrast and colours, so will need to keep some space between the table top and the background underneath.
A spotlight or flash with 'snoot' attachment will work best, but if you don't have that equipment, you can still block the light from the table top using black card (or similar).
You could also position your light source very close to the background, under the table. If you do that, you may need two lights - one from each side - to create an even spread of light across the background; even if the light only needs to cover a small area, the 'fall off' (drop in intensity) from a close-up light will be very rapid and may result in an unevenly lit image. For more information on this, check out the 'inverse square law'.
When using a strong light source such as flash, ISO 100-200 produces a less grainy image that the higher ratings recommended above. Set shutter speed to the flash sync speed specified in your camera manual.
Have fun.
>camera (ideally with macro lens, but if your compact digi camera allows close-up focussing, then that can work too)
>tripod (preferably with detachable central section that can be angled parallel to the ground, allowing the camera to face directly down)
>mini spirit level (to place on top of the camera and check it is level; not essential, but helps with Depth of Field when working at wide apertures)
>clear glass container (without water mark in the glass)
>laptop/ipad/etc (or a printed background image)
> glass table (or other form of support)
> water, cooking oil and / or food dye
> spotlight (only required if working with a printed background rather than a laptop screen)
The next update will go through the basic process, but in the meantime, here are some more examples.
