Casio | EX FH20 - High Speed EXILIM Digital Camera | How to make easy 3D images from your digital camera

How to make easy 3D images from your digital camera-A tutorial by Scott Huffer
Step 1 - Select the digital camera
First you need to select a good digital camera. I selected the Casio Exilim™ EX-FH20. This is an amazing
digital camera capable of taking 40 high resolution images per second! The benefit of this high speed
camera is for subjects that may move such as photographing a person or pet. All the photos are taken in
one second to freeze the subject at multiple viewing angles. Multiple Cameras are not needed.
Step 2 - Set up your simple studio or shooting area
The best starting point is to place an object on a stool in front of a colored background. For an example, I
placed a coffee can on a stool with a solid orange background. By picking a constant background you can
remove the background if necessary in Adobe Photoshop™ for more advanced 3D images. For now we
will keep it simple. For this technique we will mount the camera on a sliding track on a tripod. This
allows the camera to only move side-to-side. This is important. If you do not have a sliding track, then a
flat surface to slide the camera across will work fine. Make sure the track or surface is level. Place the
tripod around 3 feet in front of the subject. The camera will be moved side to side at a predetermined
distance. I use around a 12 inch sweep. We will discuss that further.
Step 3 - Pick your center point or anchor point
This is important when you line up the images after shooting. The center point is the fixed center that
will not move in the final 3D image. The farther away from the center point, the more the object will
appear 3D. You can pick a center point on the object visually, but the best way to do this is to break a
toothpick in half and make a base with a piece scotch tape to stand the tooth pick up. Place the
toothpick pointing straight up on that center point. For the case of the coffee can, I placed it point up on
the top center of the cap. See below:
You can remove the toothpick in Photoshop™ after lining up your images.
Step 4 - Take the pictures
Make sure your camera is in focus. To make excellent 3D images, you need high quality original
captures. Make sure your camera is set to the highest quality setting. For the Casio Exilim™ the quality
setting is “fine”. This part will take practice. Make sure your subject is not to dominant (it should not
take more than70% of the frame)and that you have plenty of background in the frame. The subject is in
focus and use a high f-stop to make sure that all of the elements in the shot are in focus. Set your
camera dial to the “1-40” frame burst. If you are photographing a person, then make sure the person
remains as still as possible. Press the shutter and hold down while moving the camera side to side to
your predetermined distance. I selected 12 inches. The farther you are away from the subject, the less
you will need to move the camera. The camera will save the images as jpeg files. You have compiled 40
pictures in one second capturing multiple views of the coffee can or subject. Remember not to tilt the
camera forward or back during the burst. Keep it in the plane of the tracking as you sweep your photo.
You can play back your sequence on the Exilim™ and reshoot it again if not satisfied. The subject should
be in the center 2/3 of the viewing area at all times. (Basically, do not let your subject disappear off the
camera while you sweep!)
Step 5. Download your images to your computer
Follow the instructions in the camera manual to download the images. Make sure you have loaded the
camera’s basic software. By plugging in the USB connection and turning your camera on, the computer
will recognize this camera and treat it as a hard drive to transfer the jpeg images. Put the images in a
single folder and label the folder.
Step 6. Open Adobe Photoshop™ and select your images
Now open all the images at once in Adobe Photoshop™. You may what to learn the basics of Photoshop
prior to creating the 3D image. I picked 9 of my images to work with. Why 9? You want to match the
printer resolution with the lens that you use. The simple formula for this is Printer Resolution divided by
the Lens equals the number of pixels that are under each lens. (360/40=9) Most Epson printers output
images at 1440 DPI and this number is a multiple of 360. This means my image I work with should be
720 or 360 dpi when finished interlacing with SuperFlip™ software. I am using a Micro Lens Technology
lenticular lens sheet with adhesive. You can buy 8” by 10” lenticular lens sheets with adhesive directly
from Micro Lens Technology in Charlotte, NC. I selected a lens at 40 lines per inch for my finished 3D
image. If I put 9 views under each lens then 9 X 40 is 360 or 360 dpi! So pick a range of 9 images. You
can open all images in Photoshop basically pick one and skip 3 across the sweep. Have all 9 image
opened up individually on Photoshop™. (I could have picked 18 for a finished image at 40 X 18 =720 or
720dpi or 36 for 36 x 40=1440 or 1440 dpi. The more images the clearer the final 3D image.) Remember
the number of images is directly related to the lens lines per inch and the printer dpi. For HP printers,
the dpi is 600 or 1200, therefore select 15 images for a 40 lpi lens-15 x 40 = 600 or 600dpi.
Printer output DPI/ lens lpi = Number is images selected
Step 7. Put all images into one file by dragging and dropping
The easiest way to do this is to pick the very center image as the target file. Click on the image you want
to transfer to the target file. To do this, you make sure you selected the move tool (arrow). Then on the
layers menu, hold down the shift key on the picture in the layers menu and drag that picture to the
picture of the target file. This will move the new picture to the target file. Now you have two layers.
Once the image is moved keep the target file open but close the original image you moved. Do this for
all 8 images. You should have a target file with 9 images or 9 layers. See Below
Step 8- Align your images
Layer 5 is the center image and will not move. Keep this layer on and then change the opacity to 44% of
all the layers to align the toothpick or center points. Remember you are aligning the toothpick or center
point on each image to the center image layer 5. Do this on each individual layer keeping your selected
center image fixed. You can move the images with your move tool by clicking on the layer you want to
align and then moving it to alignment. To move the layers below the target layer, then change the
opacity of the target layer 44% and keep the layers under it at 100%. Click on the layer under the target
layer and align it with the move tool. After all images are aligned then change back to 100% opacity on
all layers. You can now remove the toothpick by airbrushing or cloning. I will leave it on my image for
tutorial purposes. By this point, you should now have all images lined up to the target image. Without
this step, the image will not work!
Step 9. Crop the picture
Now that the images are aligned on the center point then crop the picture keeping the subject in the
center. If you are printing an 8 by 10 inch image, then crop it accordingly. Now save the file as a
Photoshop PSD file. This keeps all layers separate. Do not merge any layers. This should be an RGB file
at 8 bytes. This is the standard format for the PSD files.
Step 10. Save the Tiff Files and import into Superflip™
I use Superflip ™ software also available at Micro Lens Technology. Superflip™ works with TIFF files and
not jpegs. From the layered Photoshop File you created, turn on each layer separately and save the files
at TIFF files labeling them 1 through 9. Put them in a separate folder. Open up Superflip™
:
You may need to hit “sort” after importing them to give the above screen.
Step 11- Set up the inputs and Process (follow Superflip™ instructions)
For my Epson printer I am outputting 9 views at 40 lpi =360 dpi finished image. I picked 8” by 10” width
and height. Then Hit OK. You may need to run a pitch test to find the exact pitch of the lens. This is not
covered in this tutorial. After hitting “OK” then hit “Process” and follow the directions to save the
interlaced file.
The software is chopping up all the images and interlacing them together. The lens then allows for
multiple views to be seen as the viewing angle is rotated. The printed image will look like a jumbled
mess! But don’t worry! The lens is where the magic happens!
Step 12. Open in Adobe Photoshop™
This is a portion of the image. This shows the interlaced lines created by the software.
It is very important to not change the size of this image after bringing it into Photoshop! You will ruin
your image. It will not line up with the lens.
Step 13. Print and laminate to the lens
Print your image on your selected printer. I use Epson inkjet type printers. They work very well. Use high
quality photo paper. Do not use low quality paper. This will result in a poor looking image. Follow
directions from Micro Lens Technology on aligning the lens to the image and them laminating it with the
pre-applied adhesive on the lens.
Step 14. Enjoy your new 3D image!
Summary:
The Casio Exilim ™ series of cameras are very affordable and amazing when it comes to making your
own 3D images that can be viewed without the use of special glasses! You won’t believe your eyes! This
same camera can create motion images in the same manner as describe above. You would need to
select a lens designed for motion or animation and basically follow the same steps. Remember-Practice,
Practice and Practice! Take a class for Adobe Photoshop™ and become proficient. Superflip™ is very
friendly to use. If your resulted image becomes too blurry, then the camera was likely moved too much.
Shorten the distance of your sweep and experiment with the distance to your subject! The technology
has arrived and is waiting on people to master the art of 3D images. Hopefully, this has been informative
and is a good starting point to begin you exciting journey into creating your own 3D art and photos.
