Low-Tech 3-d Photography With Any Digital Camera
First, permit’s speak approximately the digicam. Any virtual digital camera will do due to the fact this isn’t always a hardware-based approach. For my instance, I used the SD4000 Canon virtual camera. While the camera is of little concern there are gadgets on the “must-have” list for this approach. You must have a software program like Adobe Photo save, Photo save Elements, or an equal program able to isolating pix into shade channels. Next, you need to personal a set of 3-d glasses with crimson and blue lenses OR one every Red (R2) and Blue (80A) lens filters.
Position the challenge between five and 8 feet in the front of the camera. Ideally, the challenge’s heritage ought to be another 8 to ten ft in the back of the point of focus. If the background is too some distance in the back of the problem there might be a little 3-D effect, if the historical past is too near it will be portrayed as a difficult mess of purple and blue. Use your feet and move the camera nearer or similarly away instead of using the zoom lens.
The real magic trick is how the twin pictures are captured. Stand with your toes just below shoulder width aside. Put all your weight onto your left foot, compose and shoot the image. Then shift all your weight onto your right foot and compose and shoot the second photograph. With composition, the intention is to keep the concern focused on the viewfinder. Tip: If your subject is someone the point of consciousness is the eyes and not the nose!
This transferring of the digital camera from left to right approximates the placement and distance between two eyes. The distinction between left and proper digicam function should be around four to 6 inches. The extra the space among positions the much less probably that foreground objects could be rendered efficiently in the very last composite photo. It will take experimentation and exercise to end up gifted at this approach.
Next, the image must be manipulated on a computer into an Anaglyph composite. For this example, I will talk about the steps used with Photoshop merchandise to create the very last composite.
Open the pair of Left / Right photos in Photo save. Here is in which consistencies pays off if you capture the photographs first left then proper on every occasion there’s never any guess as to which photograph record is which. The lower numbered record is constantly the left eye view.
Next, create a brand new blank picture the equal length and form as the picture photos. Alternately upload a white stable coloration layer to the Right photograph and make it the heritage layer. Using the Move device click and drag the Left photograph onto the Right photograph even as maintaining down the Shift key. At this factor, you may have a single image record with three layers: white background, Right photograph, and Left picture.
Click on the pinnacle maximum layer (Left photograph) to make it active and then use the Opacity manipulate to trade this layer to about 50% opaque. This allows you to see the Right photo through the Left photo. Use the Move tool to put the top Left photograph around and align the subject in each pix. (Hint: if it’s a person right here is wherein we attempt to align the eyes).
Once the main challenge is aligned return the top layer to a hundred% Opacity. Since the rims of the 2 snapshots are no longer aligned any photograph space without an overlapped picture will best detract from the 3-d effect. We need to crop this extra image information out of the final composite. Click off the eyeball icon for the center (Right) layer, make certain that the pinnacle (Left) layer is energetic and use the Crop tool to get rid of the whole thing that is not this sediment from the composite.
While the top layer is still active open the Levels tool (Ctr l+L). In the center pinnacle of the Layers dialog container is a pull-down menu, use it to select the Green channel. Now on the foot of the graph area are containers, on the proper, the field has a 0 and at the left the field has the quantity 255. Change the 255 to a 0. Then use the drop-down field and pick out the Blue channel and again set the top fee to 0. You will now have a bright purple image. Click the OK button on the Levels device
Click off the eyeball icon for the top (Left) layer and click on at the eyeball icon for the center (Right) layer. Once more open the Levels device (Ctr l+L) but for this deposit we most effective want to pick the Red channel and set its top value to 0. Once the layer adjustment has been completed click on the OK button.
There is handiest one step left. Make certain that the eyeball icon is turned on for all three layers after which click on the top (Left) layer to make it active. In the Layers box on the top is any other drop-down menu. Use it to discover and select the Screen option and we are finished! The picture on the screen should appear like a composite slightly out of registers with Red and Blue / Green factors. Put in your 3-D glasses (or use a Red digital camera clear out in front of your left eye and a Blue filter in front of your proper eye) and revel in your first three-D picture.
