Tutorial for Using Enlarger Lenses in Macro Photography and Image Stacking Part 3




This is a nuts and bolts explanation about adapting enlarger lenses to a common digital camera that accepts interchangeable lenses. The example camera is a Canon 60D DSLR. Part Three and Part Four describe the important preparations such as setup lighting issues when using enlarger lenses for macrophotography. Part Three was originally planned to cover all of the uses of these lenses. The detailed approach has proven to be popular and so the next topics that were going to be explained in just Part Three have been expanded into additional videos including Part Four and Part Five. Part Three will discuss setting up the shots you want to take. Your camera needs to be on a tripod. The object needs to have a plain background. The working distance you have will vary from lens to lens. The first setup shows the longest working distance. There will be a small amount of discussion using a motorized focusing rail. The brand of focusing rail being demonstrated is the StackShot. Part Four will show what the camera sees when the set up includes a lens that focuses very closely (only several centimeters instead of nearly 2 meters.) The springiness of the wooden floor is mentioned. Photographs should be taken on concrete floors or similar surfaces. Note the depth of field of the scene. By taking photographs at various increments of closeness, all of the field of view will be photographed. Lighting is important. The object will be photographed using two lights and with seven lights, for comparison. The color of the lights is important and they should be “full spectrum” daylight balanced. Proper lighting prevents a “lost edge”. Highlights that are “burned out” have no dynamic range that can be adjusted by a photo editing program. Part Five will show the actual taking of a set of images to stack and uploading them into a computer program. Additional videos will compare various image-stacking computer programs and there will be videos about post-processing stacked images using an image editor, such as PhotoShop.
