Diffusion Filters! (or Effect Filters in general)



Just thought Iíd make a thread and centralized zone/FM resource for diffusion (or really any special effect) with some samples. The CV 75/1.5 thread has been high jacked a bit (or maybe more of plot twist if we are being optimistic!), but here are a couple links and test photos, and Iíll post more below:

https://www.fredmiranda.com/forum/topic/1608503/26#15556673

For those that donít know, there are several companies that make diffusion filters. I went with Tiffen which is a reputable brand. The filters seem to be geared towardscinematographers historically and even now more than still shooters. However, while I like lots of modern glass, sometimes the images are simply too clinical, contrasty or not to my liking while I the AF, small, size, weather sealing, flare resistance, ability to be serviced etc. desirable. Or I might want an affect that a filter offers for a particular shooting context or subject. These filters offer the best way I have found to get a different look, often softer or more vintage, or just tone down the IQ in a transparent not gimmicky way.

I know there are various virtual filters and post processing to manipulate images in about every way, I have not had the kind of success or ease that I have with diffusion filters so far in post. But, please do drop links, thoughts or your own tests and images to enrich the threadóitís for all of use to learn. I know @HelenaH, @bjhurley@ and @highdesertmesa and @Fred Miranda have been actively discussing and can contribute helpful info/experience.

Lastly, I have made 2 raw files available for anyone who wants to try and share virtual filters so we all have a shared reference point Please manipulate away and tell use what you did. Also, I have 3 other types of filters coming I will use on a Tamron 70-180 and Samyang 75/1.8.

Some notes:
- The BlackPro Mist, which is common, has several side affects: lessening contrast by lifting shadows, halation of point light sources (see test photo of light pole), smoother tonal transitions in the light and highlights and a ďpastelĒ affect on images, which I have found to be a slight but noticeable shift in the color palate that is cooler and gives a bit of a fine matt-type texture. One other nice affect I had no read or considered but have observed is axial CA is diminished as filter strength goes up--which makes sense as tonal shift are less distinct and contrast is lowered. Bokeh is also softened as contrast again is lowered and youíre affecting adding SA.

You will find, you need to change your processing when dealing with filtered files, and your files will look different. With the Black ProMist, I really like how the filter soften clouds with light and highlight tonal transitions like the high contrast b/w posted below. In my experience, the filter allows for a high contrast push of the files that does not feel crisp or uber modern in a good way (road photo). On finely detailed or textured subjects, the filter can have a very softening and flattering affects (Yuri photo) while still retaining rendering and tonal richness.

- the strength is rated as 1/8, 1/4, 1/2, 1, 2, 3 with 1/8 being the weakest and the 3 the most pronounced. 
That metric system seems to be common across manufactures, though I have read the strength of a filter, 
say 1/8, from each maker will vary. Longer FLís generally need a stronger filter to get the same affect. 
For instance, I have found a 35mm will take a 1/8 to equal my 75mm getting a 1/4. Roughly, the 1/2 on my 
35mmís equals the 1 on my 75mm.

- the filters range in their affect. Some reduce resolution and micro-contrasts for a more flattering look but 
donít change the feel of the image and are described as transparent. Others, like the test shots might add
any color shifts, blooming, halation, modulate contrast conspicuously, change color temp, fog, tobacco 
filters, creates halos etc.

- Some filters add speckling in the bokeh due to the way the filter glass is engineered as @bjhurley@@@ kindly 
pointed out. This seems to be filter based, and only at some focusing distances with some lensesóplease
 feel to share more if you know more here.
