Lens flare creating filter, with 3D printed parts!

Featured

Hi,

in this project i want to show you how you can build yourself a "Lens-Flare-Filter" for your DSLR or Digitalcamera! With the filter you can easy create a cinnematic look on your pictures and Videos, wthout spending much money on expensive programs! We will use a few 3D printed parts, theese can be replaced with parts created in a cnc mill or by selfmade parts, but i will present you the 3D printed version i made.

So lets get started! :)

Step 2: The Case!

Now we need to make the case of the filter. The easiest way and the way we will do it is, to get a case of another filter which we dont need, or which is useless. Now it is importand, that we get a case, what is openable. You can see that is it openable if it has 2 small notches on it frontside. Otherwise it may is glued, what means it is not useable for us.

Remember to get a case what fit onto your lens!

Step 6: OpenSCAD

To create the filter I used OpenSCAD, it is a awesome program to create 3D files and make them printable...

To make a 3D file printable press 'F6' , the program will start rendering the 3D object. That will need some time... After this we have to go to File>>Export>>Export as STL

Now the program will create us a STL file, which we can convert into a "Gcode", to print it!

Step 7: The Code!

As i mentioned i created differen strengthen. I created 3: Small, Mid, Max

You can get the code for all three here:

https://github.com/Jan--Henrik/Lens-Flare-Filter--...

It is made for a 58mm lens case/lens

Just open it with the OpenSCAD program and export it a STL file...

Now you are ready to print it! :) In my opinion the large one is the best one....

You can pick the color you want, but a yellow print makes yellow flares and a blue one blue flares... That is usefull when you would like to film the sun, then yellow ones are awesome!

Step 8: Put it together!

Now we are ready to put it all together!!!

As you can see on the pictures the print fit perfectly into the case! So just put it in, dont glue it, we want it to be moveable freely!

Step 9: Screw the ring back on!

Now we have to screw the ring back on, sometimes that is a little bit difficult, beacuse of the size of the ring. Remember, when it doesnt fit so good, dont use violence, it will break!! So be careful!

Also dont screw it to hard onto it we want the filter to be moveable!

Step 11: How to use it?

Picture of How to use it?

Easy, just screw the filter onto your lens and align the line vertical. the lens flare will now be horizontal on the picture, when you photograph/film into light.

Just play around and create some nice photographs and films!

How does it works:

The light will be scattered on the line and create a light flare on that height. Very simple, easy to recreate! :)

Step 12: Thank you and Ideas!

Ideas:

Make the filter in a cnc mill

make more lines, for a cross-flare

...

Ok, that's it, i'm out! :)

It would have helped if you explained what a flare is and shown several examples. All I see is a bright light.

Jan_Henrik (author)  cyberdove5 months ago

Sorry, I will add a explanation :)

You did a nice job, but you could have got the same effect just by scratching a few marks in the glass of the original filters. No need for a 3D printer, just a pen knife.

I printed it beacuse i wanted to try it with different sizes... The tricks with the original filter and the scratch or with a fishing line are awesome, but i wanted to try something new... :P

And by the way you are a awesome youtuber! I love youre videos!

I have no idea whats going on. Is the goal to create a glowing white spot in the photo??? Could I see more images of this effect?

Jan_Henrik (author)  william13705 months ago

It adds lens flares :)

THANK YOU, JAN!!

i am not a photographer, but i came to see this because i was curious about the pic in my email newsletter...that filter across the lens made no sense to me, lol!! i particularly appreciate that at the end, you explained what this particular item is used for, and what effect will result...so many submitters just assume that the people reading the instructables are already knowledgeable, and forget those of us who -need- the clues, lol!!

so, THANK YOU!!

BLESSINGS!! :D

Thank you for reading it! :) :)

I guess you could achieve the exact same effect just by wrapping an elastic band around the camera and across the front of the lens?

Jan_Henrik (author)  TheArduinoGuy5 months ago

maybe, but a filter is much more pro looking ;)
