Homemade Photographic Light Reflector

Photography is the capture of light by film or sensors that serve as the first step in creating a digital image. Enhancing or improving the light can be the difference between a good photograph and something that will be destroyed or deleted as a failure. Light is improved by many camera accessories, including flash units and reflectors. For budget-minded photographers a do-it-yourself photographic reflector can be the preferred tool in getting the picture.

Selecting a Reflector to Build

    The simplest homemade reflector is a car-window reflector. These items are meant to be placed in the windshield of a parked car to keep the interior cool. They often have a collapsible wire frame for easy storage. Choose one with a silver finish on at least one side. Some models of auto shades can be divided into two parts to make a unit that is easier to handle.

    Another homemade reflector is more rigid. Acquire a piece of foam board and cut to the size of reflector desired. Cover the foam board with crinkled tin foil taped in place. Balling up the foil creates a crinkled finish offering a softer reflected light.

    A third option is an aluminum-surfaced camping emergency blanket. This flexible material often has one surface that looks similar to aluminum foil, while the other side is often white. The blanket can be placed over a foam board frame or a homemade framework of pipe or heavy wire.

Advantages of Homemade Reflectors

    Reflectors can be built to almost any size for special situations. Small reflectors are best for use in macro photography and in situations where portability is necessary.

    Larger reflectors can be used to light large areas but are difficult to move from location to location.

    Cost of these reflectors will be less than commercially purchased items. By keeping costs down, photographers can create several reflectors of various sizes for a variety of situations.

How to Make a Pictorial

How to Make a Pictorial

A pictorial is a series of pictures or illustrations that tell a story or illustrate instructions. Instead of a story, with a beginning, middle and end or instructions on how to do something, a pictorial might also demonstrate a concept or idea. A pictorial is a non-verbal form of communication, conveying the ideas of its creator. Artists use a wide array of mediums to create pictorials. While a painting, quilt or other medium might be difficult for some with limited artistic talents, a photographic pictorial makes a manageable first pictorial project.

Instructions

    1

    Select a theme for the pictorial. For an example, select the seasons of the year as your theme.

    2

    Make a list of the necessary pictures for the pictorial. For the example, the pictorial needs four photographs, one of spring, summer, fall and winter.

    3

    Locate an outdoors scenic area that experiences all four seasons. Ideally, select an area that experiences winter snow, fall colors and spring blossoms.

    4

    Take four photographs of the area, positioning the camera in the exact same way for each photograph, yet take one photograph during the winter, one during the spring, one during the summer and one during the fall.

    5

    Print the four photographs, making each print identical in size.

    6

    Affix the four photographs on a long narrow piece of cardboard, just long enough to hold all four photographs. Arrange the pictures in the order of the seasons and affix to the board using a glue stick.

How to Produce Fake High Dynamic Range (HDR) Images

How to Produce Fake High Dynamic Range (HDR) Images

For years I have been interested in High Dynamic Range images. These images display a greater dynamic range between the lightest and darkest areas of an image. Most images have a dynamic range of about four to five f-stops. HDR images can be a range of 10 f-stops or greater. Photographers create HDR images by photographing a scene taking multiple exposures at a normal f-stop, but also at two to three f-stops underexposed. This process is called tone mapping and the images are merged in Photoshop or GIMP into one image with an expanded dynamic range exhibiting greater luminescence and detail. GIMP has a neat plug-in script called Fake HDR that allows you to expand the dynamic range without going through the rather challenging tone mapping process. Read on to learn how to create HDR-type pictures using Fake HDR for GIMP.

*Keep in mind this is only suitable for some images and the results are not really HDR, but the effect that you can obtain is stunning.

Instructions

    1
    Open Script-Fu

    Ensure that the hdr-eff-plus.scm file that you downloaded for the Fake HDR script is in the SCRIPTS folder before opening your test file on GIMP. This can be found at //user/application support/gimp. All scripts are stored in this folder. The scripts can be downloaded from the GIMP Plug-In Registry. After you open GIMP, click on the Sript-FU tab to select the tools.

    2
    HDR Effect

    Try the HDR EFFECT. This only allows you to adjust the black layer opacity, and as you can see, when using it full strength (50) it makes the image look like a cartoon. Yes, there is more detail, but who cares? You can adjust this to lessen the effect.

    3
    HDR Toolbox

    Use the FAKE HDR EFFECTS PLUS. This allows you to adjust a lot of parameters in addition to black layer opacity. You can adjust the brightness and sharpness of the soft glow effect, which expands the dynamic range of the image. You can also adjust the saturation of the image and the level of image you want in the minimum and maximum portions of the image. Unfortunately, there is no preview, so you need to render each image and undo to begin to test the range of this tool.

    4
    Adjust First

    Adjust the saturation and brightness levels first; this will be helpful. Then adjust the dark layers and sharpness. I did this many times undoing each effect and testing the minimum and maximum levels to get an idea of what each slider actually controlled in the image.

    5

    This is the final image for now. I want to spend some time testing this application and see if I can improve the result. I like the improvement in the detail and the saturation of the colors, although I feel they might be too saturated. I also think I want to shoot an actual HDR of a scene and use the "normal" exposure with Fake HDR and then compare the results. I think I still have a lot more research and writing to do on this subject, so stay tuned.
