How to make 3D portrait? (One of the way)
Dear 3D Photo Friend,
The most desirable and unfortunately the most difficult thing in 3D lenticular photography is making a 3D Lenticular Portrait. And in my opinion, if we will find the easy technique how to make 3D lenticular portrait, it will be a huge benefit to our lenticular business. Really, the people always like to have their portraits and they always will pay willingly for portraits, especially for 3D portraits.
Today I would like to share with you one of the way about how to make 3D lenticular portrait.
At the end of this summer my family and I were on Alaska cruise, on the beautiful "Norvegian Sun" ship. That was a really nice cruise crowded with unforgettable impressions. The ship has the beautiful designed places. And, of course, I couldn't refrain from shooting the 3D portrait of my wife.
For this project we need:
- "PhotoProjector" interlacing software.
- "ViewsAligner" software.
- "MultiStereoBase" software.
- Lenticular sheet 8"x10" (20x25 cm) with lenticules run parallel to short side.
- "Ulead PhotoImpact" photo editing software.
- Tripod Add-on for multishooting.
- Digital photo camera with remote control.
- Steady tripod.
The biggest problem for shooting of 3D lenticular pictures is that we have to shoot from 6 to 12 frames from the different angles. For that I use a special device that we call as a Tripod Add-on for multishooting. Unfortunately a process of multishooting is long enough. For example, in that particular case I shot 12 frames during about 2 minutes. Of course, your model has to be absolutely motionless during this period. Unfortunately we can not use the flash to illuminate the model because the each flash will scare the model and she will move involuntarily after each flash. Hence we have to use a continuous lighting for illuminating. Furthermore I have some initial advices for you.
1. Ask your model to make her breath skin-deep because the deep breathing could be visible on portrait like motion and the portrait will be with blur edges.
2. Always use steady tripod! I took to cruise not a very steady tripod because it was lighter but then I regretted about it.
3. It is a good idea if you will find the scene with a good depth or/and long objects that go to depth of your scene. For example, I found a beautiful staircase in the ship's atrium for this session.
4. Find the place and/or the time where/when nobody will disturb you, especially will not appear inside of your working scene during shooting the frames.
5. Setup the Manual mode and Manual focus on your camera because all of your frames must have the same exposure and focus.
6. Use Remote control for shooting because it prevents shaking of your camera.
7. Shoot the same scene with several different stereobases. The reason of that is you will be able to choose the frame set with the best depth of your scene after shooting session.
Now let's start!
I have placed my camera on the distance of about 3 meters from the model. I have chosen the stereobase as 16.5 cm. If you want to define a stereobase exactly you have to use the "MultiStereoBase" software. I have made the 12 frames, please, see one of the frame below (picture 1).
As you could see the picture has a not good lighting. Let's fix it using Ulead PhotoImpact photo editing software.
In this particular case I used the next order of operations:
In Photo Effects Gallery I have chosen the Beautify Skin #3. It made the skin more natural.
Then I have enhanced the lighting Photo -> Enhance Lighting... and selected Fill flash: as 40 and Enhance shadow: as -80. And after that I have decided to add the color saturation Photo -> Hue and Saturation... as 20. I have received the picture like that (picture 2).
I like Ulead PhotoImpact graphic editor because it has many useful presettings that can improve the picture very fast and in the easiest way. Then I applied that order of operations to all of frames and saved them to one folder on my computer. The names of these saved files must be as 1.jpg, 2.jpg and so on. Where the frame 1.jpg is the most left frame.
Then I converted the picture 12.jpg as an object and put it to the picture 1.jpg. Then I changed the Transparency: of picture 12.jpg as 50% and now we see that these frames have the slope relatively to each other (picture 3). For example, you can see that the lines of poles are not parallel.
The reason of that is I used not a steady tripod. When I moved a camera along the Tripod Add-on the light tripod could not keep the camera upright. Hence I have to fix this problem. Before, for fixing such problems, I used Ulead PhotoImpact photo editing software, but it was a very complicated and long job. Fortunately now we have the ViewsAligner software. Using this software will save a lot of our time and efforts.
Launch the ViewsAligner software. Add the frames and select the Two bench marks alignment button. Now we have to place the bench marks on the line that we can use for horizontal alignment. We can use any line for horizontal alignment but it is a good idea to use some horizontal or vertical line. I select the line of atriums ceiling. I put the bench marks on left and right picture on the same places (marked by blue color) and then click the button with arrow, the software will place the bench marks to the rest of frames automatically. Then click the Alignment button (picture 4).
Hence now we have the frames without sloping relatively each other. Each of these frames has the black area that was added by "ViewsAligner" software (picture 5). This area appears because the frame was rotated.
Now we have to align the new frames by zero point and cut the frames using needed proportion.
I choose the zero point as the finger on the hand-rail. Click the button One bench mark alignment, put the marker on the finger and click the button with arrow, the software will place the bench mark to the rest of frames automatically. Then click the Alignment button and save all aligned frames in one folder (picture 6).
Before cropping we have to decide what size of picture we want to make. For example, I want to make the horizontal picture with size of 8"x10" (20x25 cm). The proportion of this picture is 4:5. Click on Cropping button and select the right proportion ratio. Then click the Crop button and save the aligned and cropped frames in one folder (picture 7).
Now we have 12 aligned and cropped frames that we can use for interlacing using "PhotoProjector" software. How to interlace and make 3D lenticular picture you could read in manual "How to make high quality lenticular 3D photos and Flip pictures for home and business".
I wish you to make many beautiful 3D lenticular portraits!
