I own a camera and i shoot pictures, i don't really declare myself as photographer because it was overly used. The first time i saw Demb Diffuser is when i helped my friend for videography during his wedding, the hired professional photographers are using one. Since then i went on internet search and found out it was quite expensive for just some bouncing piece and a diffuser??
I don't really like DIY photography equipment actually because most of the time they are hardly presentable (not happy to the eye, LOL) But i wanted to try out the effect, so i made a very rough one (as below) and test it out, results are not bad!
So here's how you can make one in under RM15!
Basically here's what i used, a transparent plastic to hold A6 (Daiso RM5.30) , velcro and flexible strap (RM5.30 x 2), the most important bit, the price tag holder (RM1.90) and a magazine plastic from Institution of Engineers. I have another sort of rubber band thingy, where i have it during run events. (not shown in pic)
Just dissemble the clip so you have a good surface to wrap on or hold on.
Wrap the clip with band or strap so it hold in place, clip the plastic holder with white paper in it, lastly cut a shape for diffuse material ( the magazine cover ), all are pretty self explanatory.
Below is the picture for comparison canon 600d, iso1600, 1/80, f /5, External flash bronic S38:
1. Shot with built in flash, direct flash, notice the harsh shadow
2. Shot with external flash, pointed direct, lowest power, quite dark.
Conclusion: DIY Demb is better compared to not using any diffuser, more control of light directional and diffused light, but downside is waste more power (i believe this can be improved by using a reflective material instead of white bounce card!)
And here is my final "presentable" version, which i think is far visually acceptable than the draft version. The diffuser is some kinda flexible white plastic sheet, with velcro straps and cable straps to hold the bounce card in position.
