Backlighting is where you are illuminating your subject from the back, as opposed to from the front, or the side. Working with backlight you can silhouette your subject, or give them a glow. To Silhouette your subject, you would meter for the sky and to create a glow around your subject, you would meter for the subject itself. You need to place your subject in front of your preferred light source and allow that light to illuminate your subject. If you are using the sun as your light source, different times of the day will give you different types of backlighting. The lower the sun falls, the softer the light will feel. You may find that sometimes you will have to move yourself into a position where your camera can autofocus or switch to full manual, as the light can be so strong that your focusing point struggles to find what it is you want to focus on.

We received a CoolLED Illumination System prototype which was integrated and tested over February 2017. The first microscope with a CoolLED Illumination System was sold just later that year. In addition to meeting technical specifications, CoolLED was very quick to react to changes in our situation and provide appropriate solutions.
Reflected light can be found everywhere, on most surfaces. Reflected light is literally the light that is reflected from a particular surface or material. If you were to shoot a portrait next to a white building, the light hitting the building would be reflected on to your subject, creating a soft light. If you were in the middle of the red Moroccan Atlas Mountains and you were to shoot a portrait, there would be a softer red reflection coming onto your subject from the ground. Or, if you were doing a portrait session outside and you wanted to bounce some additional light into your subject’s face, you could use an actual reflector. They normally come in two colours; one side gold, and one side white.
Light: it is the main component for every image that you will take. It does however come in many different forms, producing very different results. Some of these types of light are diffused, backlit and reflected. There will be times when each of these types of light is more readily available than another, or even in some cases multiple types of light at once. Some people create their full photographic style by using a certain type more, or less, exclusively in their work. But, knowing how to first spot the different light forms will allow you to take full of advantage of every scenario and add depth, variety and a sense of individuality to your images.
20201114 — It seems that there is some disagreement as to whether the highest light level is 255 or 256. Both DeepSea and Eureka show the highest as 255.
You can use diffused lighting to your advantage in a great way. If you are shooting portraits on an overcast (diffused) day, you are pretty much shooting with nature’s own softbox. You will be able to work with your subject easier, and have different angles to shoot from, because you won’t be limited by the harsh lines and shadows that undiffused light can create. Overcast (diffused) lighting is preferred by many photographers, as it is a flat and even light. If it were a particularly sunny and bright day, shooting in the shade would also offer you some diffused lighting.

Andor has worked with CoolLED to transition multiple product lines to the use of LED illumination in place of older technologies. This allows us to take advantage of new levels of illumination stability and synchronised device control to enhance our products in a competitive market place. As well as meeting stringent worldwide compliance needs, CoolLED has also been extremely reactive to our specific needs when it comes to optimisation of their solution to our hardware and therefore target applications.
CoolLED designs and manufactures LED illumination for microscopy and is ideally placed to deliver OEM illumination requirements.

Diffused light that which is not harsh and direct, it has been softened in some way. A great example is when you are outside and the sun is shining, with no clouds in the sky. The light is harsh and you will notice that there will be a lot shadows falling on or around your subject. But, if clouds are in the sky and they block out some of that harsh sunlight, the light then becomes diffused.

This particular image shows the use of diffused lighting, using the shade of the building to soften the light, while also reflecting light shades back to the subject.
Whilst we offer a wide range of LED microscope lighting systems which meet the needs of many scientists, we also understand that something out of the ordinary is sometimes required.
Diffusion light helps you do this by masking the direction that each source hits the subject. Direct light will often cast harsh, unnatural-looking shadows.
Medipan has used CoolLED LED Illumination Systems for many years. The ability to control the excitation intensity of our assays for sample analysis has been crucial for the successful performance of our Aklides system. Instant on/off control through our system software means that illumination is fully integrated with the product. CoolLED has worked closely with Medipan as we have developed our products to ensure compatibility and performance. A responsive helpful supplier allows our scientists and engineers to focus on our core capabilities when developing products for the life sciences.
