How To Guaranteed Splash!!!

 

Did you say guaranteed splash with MJKZZ WDK? Yes! This works for any other type of equipment, as long as it has a digital reading.

 

This tutorial is an addition to the user manual for my upcoming super controller with 6 channels and 16 different sizes and delays for EACH channel. Along with a precision valve. However, this method should work well with current WDK types of equipment, too.

 

The method described here is very generic and independent of the thickness of water solution, independent of water pressure, independent of the height of setup . . .

 

Without further ado, here is how:

 

Step 1 -- Finding the exact moment when a drop hits the water surface. -- adjust FD and take pictures so that the drop is just about to hit the water surface (shown as 1 in the above picture). Fine-tune it until you get 3 in the picture where the drop is halfway in the water surface. Record the FD, in the above picture case, the FD is 345. For your setup, it could be (most likely so) different.

 

Step 2. Adjust FD until you get the tallest worthington jet like the 4th one in the above picture. Record the FD reading, in the above picture, it is 485.

 

Step 3. Set the number of drops to 2. Set the size of the second drop to be moderate, in the above picture, it is 60, the same as the first one.

 

Step 4. Calculate delay between 1st and 2nd drops: 485(peak) - 345 (reaching surface) - 60 (size of the second drop) = delay needed between 1st and 2nd drops, which in this case 80. What does it mean? It means if the second drop can reach the water surface while the first one is peaking, there must be a collision (unless the worthington jet is too thin and not going straight up)

 

After setting D1=80 (delay between 1st drop and 2nd drop) I got collision splash like those shown as 5 and 6 in the above picture.

 

This is very repeatable, though less interesting than those by pro dropper, nonetheless, it is a start.

Focus Stacking & Extreme Macro

Focus stacking is a powerful method to extend the depth of field by taking a series of images at different focal planes and use computer software to pick the sharpest part of each image for the final result. One way to acquire such a series of images is by moving the camera towards or away from the subject (or by moving the subject towards or away from the camera) so that different parts of the subject will be in focus in each image. Then by applying a computer algorithm, these images will be combined into one sharp image.

In order to move the camera (or the subject for that matter) and automate the process of image captures, an automated rail system is a preferred method. However, current products on the market are extremely expensive and many macro photographers have to do it manually which is tedious work to do. Besides expensive rail systems, good stacking software is either expensive (but really good) or difficult to use (though free)
