While the answer to this is very individual and the right set—up varies from person to person, I can tell you what I have chosen for the time being. Wildlife and Birds: I continue to use the Nikon crop sensor DX bodies for this type of photography coupled with either the Sigma 150-600mm Sport lens, the Nikon 500mm f/4VR lens or the Nikon 80-400 lens. The 500mm lens is often coupled with the latest Nikon 1.4x teleconverter to achieve a focal length of 700mm. When combining this with the 1.5x crop of the D7200 or the new D500 camera, the effective reach is sufficient for almost any subject.

    Infrared Photography John Caplis & Joyce Harman Harmany in Nature www.harmanyinnature.com www.savingdarkskies.com Why do infrared photography? Infrared photography offers many unique creative choices you can explore in image making • Excellent monochrome images • Sunlit foliage turns white • Blue skies appear very dark • False color can be applied for dream like scenes • Skin tones are ghostly white • Can be shot in the harsh light in the middle of the day A human eye can see light from 400nm to 700nm on the electromagnetic spectrum. This range is called ‘visible light’. IR photography uses “near infrared light” which is in the range of 700nm-1400nm. These wavelengths are longer than visible light and can’t be seen by humans. How IR filters work There are two types of infrared filters, ones that block IR light while passing visible light and ones that block visible light while passing infrared light. The IR blocking filters are used in stock digital cameras to prevent unwanted IR light from reaching the sensor, which is sensitive to near infrared. In infrared photography we want the opposite, to block most or all visible light and only pass infrared light. Two ways to do IR photography – Stock vs IR-Converted Cameras Stock Camera with Converted Camera with Screw-on external IR filter Internal IR filter • Dim or no preview image • No screw on filter required • No autofocus • Normally bright preview image • Exposure metering can be difficult • Autofocus using live view • High ISOs & long exposures • Exposure metering can be difficult • Requires tripod • Low ISOs • Tripod not always required Camera conversions • Life Pixel https://www.lifepixel.com • Kolari Vision https://kolarivision.com Using Stock Cameras for IR Photography Stock digital cameras have a limited range of sensitivity to infrared light.

  • Macro Photography Camera Richard J
    Evaluating A Macro Photography Camera Richard J. Nelson Introduction My company, AMF, purchased a general-purpose digital camera five years ago, the Sony Mavica, model MVC-FD83. The digital capability and floppy disc drive media proved very practical for general documentation purposes. The floppy discs made it convenient for any employee to work with the images. After about 20,000+ images the floppy drive wore out and a new camera was needed. Meanwhile I had personally purchased a Nikon Coolpix 995 camera with a 3.3 Megapixel resolution (a big improvement over the Sony Mavica 0.9 megapixel resolution) and close focus (2 cm) capability. This became a consideration for an AMF camera and we ordered one on eBay, which was lost by the USPS - it was insured. Earlier in 2005 I purchased a Sony T1 with a Magnify mode that featured a very close focus (1 cm) and 5- megapixel resolution. This camera has provided many of the images used on posters, reports, fundraiser book, procedures, and power point presentations, especially for the BPB project. The ability to produce a large image of a very small object has proved very useful for our engineering and publicity projects. The Sony T1 works especially well as a general documentation camera for me because I always have it with me, I have extra memory cards, 1 GB total for about 500 images, and 2 extra batteries for any photo shoot requirements. All of this fits in my shirt pocket and is with me 24/7. The T1 has two serious limitations. The first is sharpness with magnification, and the second is working distance for lighting.

  • Digital Infrared Photography by Vega Buchbinder
    Digital Infrared Photography By Vega Buchbinder The advent of digital cameras has made infrared photography relatively easily accessible. No longer does one need to handle and process infrared film in the dark under stringent conditions. In the days of film photography Kodak’s film HIE High Speed Infrared Film was the première infrared film, noted for its extensive range. Kodak has stopped making this film in 2007. Today, with a digital camera, an infrared filter, and a tripod, anyone can explore the near infrared spectrum photographically with ease and repeatable results. Using digital infrared (IR) photography one can produce fascinating images that can look surreal, or of an alternate reality. In addition one can use many variations in image rendering, ranging from black and white, to false colors, in order to create artistic images. What is infrared photography? What makes digital infrared photography possible is that the silicon sensors used in digital cameras can “see” into the infrared range of the electromagnetic spectrum. From short wavelengths to longer wavelengths, the electromagnetic spectrum is made of gamma rays, X- rays, ultraviolet rays, visible light, infrared rays, radar, FM radio, TV, and AM radio. The human eye is sensitive to wavelengths from approximately 400 to 700 nanometers (nm), which is the wavelength range for visible light. The CCD and CMOS sensors in digital cameras can easily “see” further into the infrared region to about 1050 nm, which makes IR photography with a digital camera possible today. Note that this part of the IR range is called the near infrared. Thermal infrared rays are much longer, and are not detectible by the CCD or CMOS sensors in our digital cameras.

  • Macro Photography
    MACRO PHOTOGRAPHY Dave Bremner February 21,2019 What is it? It is extreme close- up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life size (though macrophotography technic ally refers to the art of making very large photographs) (Wikipedia) Think small. Size matters in reverse! You want to make something that is small, larger than life size if you can. What is needed for Macro: The following is a list of gear, ideas, and means of achieving MACRO 1) Camera (obvious) DSLR, mirrorless ILC, or compact camera, or cell phone 2) Macro lens 1:1 magnification if you have one, or compact camera with macro setting, or a lens with macro setting depicted usually with a flower either on the camera or on the lens. The lower the ratio the better ie 1:2,1:3,1:4 etc. 3) Tripod and remote or knowledge of using the timer mode on your camera to prevent camera shake during the exposure. 4) You want to get as close to the subject/object that you want to shoot and achieve optimal focus and DOF (depth of field for the articles in the image that you want to display to your taste.) 5) Do you want abstract , or accurate recognizable depiction? Most mundane everyday things (insects, snowflakes , water drops can be almost unrecognizable the larger the final image can be made). Try shooting something like a cheese grater, or cutlery close up to obtain something abstract. Cheese Grater Cutlery and lens ball 6) PATIENCE: This is something I do not have a lot of and you may find yourself expending yours trying to obtain the shot you want in the proper light and composition.

  • Plant Macro Photography
    Plant Macro Photography PUBLISHED - 09 JUN 2020 Plant Macro Photography Macro photography of flowers can be done both inside and outside. There are so many opportunities to open up a whole new world of photography and to give you a new way of visualising the world to improve your composition. Plant Macro photography can be shot with either a tripod or handheld, it’s your choice, however, you should get much sharper images if you do use a tripod. You can use any lens that allows you to close focus, but to get the best results something like the Nikkor 40mm or 85mm DX micro lenses or the for full frame cameras the Nikkor 60 or 105mm micro lenses would be perfect. Handheld Macro Photography 1 of 6 If you are shooting handheld, make sure your shutter speed is high enough to ensure a sharp image. This will vary between cameras and lenses but a good shutter speed to aim for would be a minimum of 1/125th or ideally around 1/250th if your subject is not moving. If your lens has a Vibration Reduction (VR) I would suggest setting that to on. Set your ISO to the lowest native ISO on your camera either 64, 100 or 200 and then turn on Auto ISO. You can use either P (Programme), S (Shutter Priority), A (Aperture Priority) or M (Manual) modes. To get the best results we would suggest using manual mode as you can control both the shutter speed to get a pin sharp image and your aperture for either a limited or large depth of field.

  • Macro and Close-Up Photography
    Photo by Daniel Schwen Macro and Close-up Photography Digital Photography DeCal 2010 Nathan Yan Kellen Freeman Some slides adapted from Zexi Eric Yan What Is Macro Photography? Macro commonly refers to large-magnification photographs -i.e. showing small subjects in great detail Magnification is given as a multiplicative factor (e.g. 3x) or a ratio (e.g. 1:2). Lenses which provide at least 1:1 or 1x magnification are considered “true” macro lenses. Magnification factor: size of image recorded on sensor, relative to size of actual object Sometimes referred to as “micro” – same thing Common subjects: Insects Head of a blow-fly 5x magnification Common subjects: Flowers Tulip Common subjects: Small detail of everyday objects Cigarette tip Magnification Lens Sensor Object size: x Image size: x Magnification: image size / object size = 1 Magnification Lens Sensor Object size: x Image size: 0.5x Magnification: image size / object size = 0.5 Magnification Pixel density also determines the level of detail Lens Sensor Object size: x Greater pixel density mean more pixels representing an image of given size: more detail Image size: 0.5x “Crop” sensors often have similar # pixels in smaller area = greater pixel density The Optics • Two factors affect magnification: focal length and subject distance • M= hi / ho = di / do the shorter do or longer di would give larger M. • Large magnification is achieved by placing lens further from sensor, or allowing lens to focus closer Lenses in Macro Photography Regular macro lenses • Long lens barrel design (to

  • 6 Tips for Near-Macro Photography with a Telephoto Lens a Post By: Elliot Hook
    6 Tips for Near-Macro Photography with a Telephoto Lens A Post By: Elliot Hook Macro photography is the art of capturing the fine detail of very small subjects that may not be able to be seen by the naked eye. Technically, to fall under the term ‘macro’, the subject should be captured with a reproduction ratio of 1:1, i.e. the subject will be captured on the sensor at 100 % life size. Macro lenses are specially designed to minimise the focussing distance, allowing the photographer to get closer to the subject and so increase the reproduction ratio. There are a number of other techniques that can be used to help achieve the desired magnification without a dedicated lens (extension tubes, close-up filters, reversing rings), however, one of less often considered techniques is to use something that you probably already have in your kit bag: a telephoto lens. Milking Bonnet Fungi (Mycena galopus) Telephoto lenses offer extreme magnification but generally have much larger minimum focussing distances pushing the photographer further from the subject and so reducing the reproduction ratio. Some telephoto lenses, when combined with camera systems utilising smaller sensors, are able to offer 1:1 magnification (‘true macro’) however, typically, telephoto lenses are limited to close-up photography, at near-macro reproduction ratios. Using a telephoto lens for this kind of work offers a couple of advantages over a dedicated macro lens that are a direct result of the large minimum focus distance. Because the working distance to the subject is in the region of 1 metre (compared to 15 – 30 cm of standard macro lenses) the risk of disturbing your subject as you compose your shot is much reduced.

Bokeh has been defined as "the way the lens renders out-of-focus points of light".[6] However, differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting—"good" and "bad" bokeh, respectively.[2] Bokeh occurs for parts of the scene that lie outside the Coarse bokeh on a photo shot with an 85 mm lens and 70 mm entrance pupil diameter, which depth of field. Photographers sometimes deliberately use a shallow corresponds to f/1.2 focus technique to create images with prominent out-of-focus regions. Bokeh is often most visible around small background highlights, such as specular reflections and light sources, which is why it is often associated with such areas.[2] However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image.

  • Choosing a Lens of the Right Focal Length That You Will Get the Appropriate Angle of View
    How to choose a camera lens Understanding the technology SUMMARY When you buy a camera, make sure the lens is suited for the intended purpose. With the right lens, you can greatly enhance the results you achieve in a particular type of photography and, by having a variety of lenses, you can greatly extend the usefulness of your camera. This paper provides a basic introduction to the principles of camera lenses. It explains the terminology: what is meant by focal length and f/number? Choose the right lens and taking good photographs becomes so much easier! The Basics The most important component of your camera is the lens. It’s no good having a camera with an impressively large number of megapixels if the lens is not up to the job. A lens has two basic properties: Focal length This determines the field of view of the lens. To match human vision, you’d need a lens with a focal length of about 35mm (in photography, focal length is always measured in millimetres). The normal, or standard, focal length for a camera lens is 50mm - anything smaller is called wide-angle, anything greater is called telephoto. A camera lens offering a range of focal lengths is called a zoom lens; one of fixed focal length is called a prime lens. f/number The ratio of the focal length of the lens (f) to its effective diameter: the size of its ‘window’ on the outside world , or aperture. The f/number is a measure of the light gathering power of the lens (called its speed).
