How to make Flip pictures?

FLIP picture is the lenticular picture that usually consists of 2 or 3 frames. You can see them on the different viewing angle.

These are great looking and easy to produce pictures. You will be able to amaze your friends and customers when you will show them the FLIP pictures. These pictures can be small for holding in hands or albums and big for framing and hanging on the wall. When picture is on the wall there is an interesting effect of changing pictures if you walk around the picture.

Making FLIP pictures is a great foundation for establishing new or growing already existent photo business. I make thousands of FLIP pictures and I know exactly that the customers always love these pictures.

Let's make our first FLIP lenticular picture using the frames that you can see below (pictures 1 and 2).

Picture 2

That is Mickey Dog, he is the youngest brother of Mickey Mouse. :-) I think he has a jet engine somewhere close to tail, because he is so fast. I spent more then one hour shooting them and shotted more then 50 pictures and in most of my pictures I got just his tale. :-)

Before interlacing we have to prepare all frames using one of the Photo Editing Software. Usually I am working with Ulead PhotoImpact. I have been working with it for more then 8 years. In my opinion it is the best software for fast and easy photo editing. I tried to use other graphic software, like Adobe Photoshop or Corel Photo-Paint, but I found that using PhotoImpact is easier and give great and professional looking results. I know that many graphic designers prefer Adobe Photoshop, but I do not need to make very complicated graphic works and I know that Ulead PhotoImpact can do all that I can imagine and much, much more. But the price on it is just $89.99 USD. Compare with Adobe Photoshop that costs $649 USD.

Of course, if you used to work with another Photo Editing Software you can prepare all frames using it. But I would like to base on PhotoImpact. If you have a good experience with your software you will be able to do all steps that I describe, using it.

Okay, all my preliminary thoughts are finished. Let's start!

1. First of all we have to decide what size of lenticular picture we are going to make. In this case I want to make the picture with size 4"x6" (10x15 cm). Proportion of this picture is 2:3.

Actually my frames have the resolution of 2272x1704 pixels, with proportion is 4:3. So, we need to crop the pictures using proportion of 2:3.

Let's calculate: 2272 : 3 x 2 = 1514.7

So, we have to crop the pictures up to size 2272x1514 pixels.

Open the mickey2.jpg file in PhotoImpact (picture 3).

Picture 3

Choose Crop Tool on the left side of Working Area. On the top you can see 4 small widows Left, Top, Wight and Height. Print to these windows the following values 0, 0, 2272 and 1514. Then move mouse pointer to the picture's working area, click and keep left button of mouse and drag the working area downward. In this case the dog will be in the center of picture and we will cut the unnecessary objects from the top of picture off. You will see the area tinted to brown color. This area will be cropped away. Then click Crop button (picture 4).

Repeat same steps with the second frame.

Now we have two frames with resolution of 2272x1514 and proportion of 2x3 exactly what we need (pictures 5 and 6).

2. Run PhotoProjector software.

2.1 We have to make a pitch test. This test allows us to calibrate all printing process. We have to get the file like shown on picture 7.

Picture 7

Click "Pitch test …" button. Setup the values as shown on picture 8.

Picture 8

Setup the values:

Click "Save" button and write the name of Pitch Test file, for example as "pitch 0.1.tif".

Open the file "pitch 0.1.tif" in Ulead PhotoImpact Photo Editing Software (picture 9).

Picture 9

Check that resolution of this file is exactly 720 ppi (pixels per inch). For that you have to click Format Tool on the top and choose "Resolution…" from menu. "Current resolution:" must be 720, if you see another value you have to setup a resolution as 720 (picture 10).

Picture 10

Print this file with the best quality printer settings. Put your lenticular sheet on previously dried up print and find the strips where black waves run towards when you move you hand along strips. The real value of your "Lens Per Inch, lpi" is between them. For example, I saw that the strips where the waves run towards have values 60 and 60.1 lpi. Then we have to repeat a pitch test but in window "Step of Lenses per inch, lpi" we have to put the value of 0.01 (picture 8). Click "Save" button and create a file "pitch 0.01.tif". After printing and drying, put a lenticular sheet and find the strip where black and white colors change simultaneously along all strip (without wave). In my case I got that the strip with 60.05 lpi is the best.

We have to write this value to the Lenticular Sheet Type Database of PhotoProjector software. Click "Open Database..." button, choose "3D 60 lpi" image type, change "Lenses per inch:" to 60.05 lpi (picture 11) and save it.

Picture 11

2.2 Let's choose "Image Type". For that click "Open Database…" button and then the "Add" button (picture 12).

Picture 12

Setup the values:

Save this Image Type using "2views 12px depth0" name.

2.3 Now we are ready to make an interlacing image.

In "Lenticular sheet type" window choose the value "3D 60 lpi".
In "Image Type" window choose the value "2views 12px depth0".
Click "Add sequence…" button (picture 13) and add the files "frame1.jpg" and "frame2.jpg".

Picture 13

I want to make a lenticular picture with size 10x15 cm. Therefore setup "Width of output image, cm" as 15 cm.
Setup "Print resolution, dpi:" as 720 and "Type:" as Flip.

Click "Settings…" button and check "Horizontal orientation" and "Mirror strips" (picture 14).

Picture 14

Then click "Create interlaced image" button and save interlaced picture "Mickey Flip.PNG" (picture 15) on a hard drive.

Picture 15

2.4 Open "Mickey Flip.PNG" file in Ulead PhotoImpact Photo Editing Software. Check the resolution of file as shown above and print it with the same best quality settings as earlier. You get an interlaced picture. Now you have to glue this printed interlaced image with your lenticular sheet as described in manual "How to make high quality lenticular 3D photos and Flip pictures for home and business" and you will get lenticular flip picture. When you will change the angle of view you will see the different frames as shown on picture 16.

That is it!
Congratulations! You made your first FLIP picture!

Best Wishes,
