Nice to see a budget tutorial. What ring flash are you using? Normally i see people recommending the godox ar400, but damn...it is a little bit expensive 😅
Yeah they can be expensive so I like gong budget where possible (pending they still work well lol). I use the yongnuo ring flash. I have for the last 5yrs. The only problem with it is that the plastic battery compartment cover will break at some stage so I use a rubber band to hold it in place but you can buy replacements
Great videos, i interested in making for my own. Can you please tell me which polarization sheet is used in dental photography ? Is it 0°, 45° or 90° ?
Thanks for this video! I have two questions: -I have made the product but when using my polarising filter the photos come out much darker - which is not supposed to happen! any ideas what I am doing wrong? -How did you produce the life size images of the camera flashes to use as stencils?
- you have to decrease the F stop when you take the photos - I copied photo of the flash from google images, pasted in word doc, measured it in real life, then made sure it was the same size in the word doc
It's a bit involved - get photo of your flash from online and put it in word - measure the actual size of your flash - crop the image in Word to make sure it is cropped at the edges - change the size of the image to be the same as your measurement - print
@@DrPaulsDentalWorld thank you so much Dr .. its so helpful i have another quastion .. when i put the polarized film in front of the lens it gives bad resolution image dose that normal or the quality if the film play roule? thank you so much in advance
The quality of the film does play a role - if it isn't really clear it will not make a clear image. Have you checked that there isn't an adhesive layer on the film?
You would want to take the photos with other lights off/ in a dark room. Otherwise every other light that hits the surface will be unpolarized (ceiling lamps, ambiental , sun, medical equipment lights).
I'll have to experiment by turning the lights off, but for the purpose of what I'm using this for, I've never felt the image wasn't right. Good tip though
I made the filter according to u, and even check the film placement cross-check with the laptop screen, but when doing intraoral photography it dont work, shows me a flash reflection ....what could have been wrong.

When you don't have a crafts exacto knife but you're a dentist so you have a 15 blade 😂 Thank you for the tutorial!
🤣🤣 Whatever works right!?

It should be linear, which I think is 0°

That's worked great, thanks!@@DrPaulsDentalWorld
Awesome 👌
where can i get the real life size of the flashlight?

I was wondering where you got the polarised sheets from. Thanks!
I got it from ebay 👌
@@DrPaulsDentalWorld please link DR!
If you type in linear polarized sheet, you will see many options 👌
@@DrPaulsDentalWorldwill any polarization film sheet work?
Yes, as long as it is linear
Thanks for the video! Do you have the picture file (.jpeg) for the live size Canon MR14EX you showed in the video?
You're welcome! I just got them off of google and then put them in a word document, making sure they were life size

Check this video. Has great examples about cross polarized technique ruclips.net/video/uWtoZs1jgOg/видео.html
Great, thanks for sharing 👍
You're welcome, enjoy!

Direction of filter might be wrong.

Hi dear Paul. I bought polarizing film but it did not produce a polarizing effect.
Hi Ali, either you bought the wrong film, or you didn't follow the instructions 100% correctly. Sorry I can't give you more answers
@@DrPaulsDentalWorld Could you please send me a link to the polar film?

@@DrPaulsDentalWorld Thank you. I got the polar effect. but the image is very blurry. Could the polar film be thick?
Did you take the clear plastic off of it?
