4/9/2023 0 Comments Diy fisheye lensI had the change to try a few things first of all to understand the store coverage of the fisheye frame, this is something I had not tested before but I had built a little model. Think of and take care of your gear first.It was time to get wet and test the Canon 8 – 15 mm fisheye on the GH5 in the pool so I made my way to Luton Aspire with the help of Rec2Tec Bletchley. They aren’t worth doing if they damage your gear in the process. One last thing, all these DIY hacks are fun and cool mostly, but you must be careful with them. Experimenting and combining DIY hacks for your photography can lead to very unique-looking images. I hope these examples will help you produce some creative and fun effects in your images. There are some lens filters that provide the same effect, only slightly better than the pinhole trick and easier to mount, but they will still be far from a real fisheye lens. This is done by duct taping a door peephole with wide angle of view (fisheye) in front of the lens. Images don’t really look that good, but for many photographers it doesn’t matter. DIY Fisheye – This one is just for the sake of having a fisheye effect.Or you can simply use a magnifying glass for the same purpose (and same drawbacks). You can also purchase some cheap magnifying filters that will let you reduce the minimum focal distance by sacrificing image quality. Vintage lenses are better for this purpose because of the aperture control. You can stick a fixed focal length lens upside down on an existing lens by using reverse rings, or you can stick the fixed focal length lens directly on the camera upside down. Cheap Macro – There are so many ways to do this.That will pretty much work with a mirror as well, just not so great, and the edges of the mirror will sometimes be visible. It is a fun process that can fill up otherwise boring parts of the background of the images, for example. You can achieve that by holding the prism near the lens in order to project an image on the top of the image you are trying to get. You can use a prism (the viewfinder part of an old camera, or you can buy a cheap broken vintage slr) to simulate something like double exposure. Double Exposures – All you need is a mirror or a prism.I wouldn’t recommend that since it takes hours of cleaning after it, and there is the risk of damaging the front element in the process. There is another way to do this, but that involves smearing something on your lens, like vaseline. ![]() You can use colored nylon to simulate light leaks and similar color casting effects. Don’t cover all parts of the lens since you won’t be able to get anything in focus. Wrap that around your lens, and let some of it stick over the front end of the lens in order to diffuse the light entering the lens. Creating Dreamy/Soft Images – All you need to get this effect is a sandwich bag or wrapping nylon.Just so you know, this will generate decent amount of vignette, and you’ll probably lose some light. It might take you few attempts till you get the right size of the hole. Just cut out a hole in the middle of the paper with the shape you want your bokeh (specular lights) to be in, stick that in front of your lens as a makeshift filter, and there you have it. All you need is a piece of paper which is bigger than your lens filter size, and a scalpel/scissors. Producing Custom Bokeh Shapes – You can alter that as well.The color cast can be fixed in post processing by adjusting color balance and white balance. ![]() The cons, however, are that you probably will lose some sharpness you’ll have to hand hold the sunglasses in front of the lens, and there will be some color cast since almost every pair of sunglasses has a certain base color coating. The pro is that you get a ND filter or Polarizer for free. You can even use polarized sunglasses to act like a polarizing filter (not as circular polarizer though). You can use regular sunglasses to act like a neutral density filter or you can use graduated glasses to act like graduated neutral density filter. That means it can do the very same for the lens.
