Light Leak | FUJI X WEEKLY

Fujifilm’s Hidden Feature: Advanced Filters (plus, what Fujifilm should do with it on future cameras)

There’s a feature on most Fujifilm cameras that few use—you might not be aware that it even exists—called Advanced Filters. Fujifilm introduced Advanced Filters in 2013 with the X100S and X20. With the exception of a few early models, your Fujifilm X-series camera has Advanced Filters (however, GFX models does not have it). Find Advanced Filters on the Drive Dial or Drive Menu (depending on the specifics of your model). For older cameras, Advanced Filters are JPEG only; however, on newer models, you can save a RAW file in addition to the JPEG. Since its initial implementation, Fujifilm has left this feature unmodified, offering the same options on each camera generation.

Why are the Advanced Filters so obscure and not widely used? Worse, why is it actually detested by some who have tried it? Well, the short answer is that Advanced Filters aren’t “advanced” at all, and are probably the most gimmicky and sometimes cringy thing Fujifilm has included in what are otherwise sophisticated cameras. My personal opinion is that some of the Advanced Filters are okay, others aren’t particularly good, and some are definitely out-of-date. Let’s take a look at each Advanced Filter.

Toy Camera

Fujifilm describes this Advanced Filter as “a retro toy camera effect”, which is to say that it is roughly modeled after a Holga or Diana film camera aesthetic. It’s intended to be a “lomo” look. It seems to be the Provia Film Simulation with a yellow cast and some vignetting.

Miniature

This adds blur to the top and bottom of the frame, similar to using a tilt-shift lens. When you are photographing from an elevated vantage point, the Miniature Advanced Filter can give the illusion that the subject is a miniature model. It’s better to use an actual tilt-shift lens to get this effect, but if you don’t own one, this is an easy way to approximate it. Like a lot of the Advanced Filters, I believe that it is based on the Provia Film Simulation.

Pop Color

Pop Color is my favorite Advanced Filter. It more-or-less resembles Fujichrome Fortia 50 film, and in my opinion Fujifilm should make Pop Color the next Film Simulation and call it Fortia. Perhaps they’ll need to fine-tune some aspects of it, but whatever it is that they need to do, I believe that Pop Color absolutely should graduate from Advanced Filters.

High Key/Low Key

The High Key Advanced Filter creates a bright overexposed image, while the Low Key Advanced Filter creates a dark underexposed image. There’s nothing especially special about High Key and Low Key, as both can be easily replicated using the Provia film simulation. You might occasionally use these two in lieu of having a Film Simulation Recipe programmed into C1-C7 with a similar look, but I don’t believe many people are doing that. Instead, you could use Recipes like Bright Kodak or Low Key for better results.

Dynamic Tone

“Dynamic tone expression is used for a fantasy effect,” is how Fujifilm describes it. What it reminds me of is HDR photography with aggressive tonemapping, which was all the rage 15 to 20 years ago despite being hideous.

Soft Focus

The Soft Focus Advanced Filter is kind of like setting Clarity to -20 and Sharpness to -10 on your Fujifilm camera (if that were possible) while using the Provia Film Simulation. In my opinion, it’s much too strong; instead, it should be integrated into the Toy Camera Advanced Filter with the options of Off, Weak, or Strong (with the current iteration being Strong).

Partial Color (Red, Orange, Yellow, Green, Blue, Purple)

Above left: Partial Color Red Advanced Filter; Above right: Partial Color Green Advanced Filter

The six Partial Color filters are the Monochrome film simulation (with everything set to factory defaults), but with one color recorded (either red, orange, yellow, green, blue, or purple—the singular color is the Provia Film Simulation). This is another effect that was popular 15 to 20 years ago, but is not currently trendy.

In the past when I’ve suggested that Fujifilm should consider overhauling Advanced Filters, I was surprised by the pushback. There are people who use these, and surprisingly some of the options are beloved by some photographers. The best thing that Fujifilm could do is to allow them to be customized with White Balance, Dynamic Range, Grain, etc.. For Toy Camera, it would be cool if you could choose the Film Simulation, too. If Fujifilm were to ax half of the Advanced Filters, I don’t think most people would mind (or even notice).

Let’s hypothesize that on the next generation of Fujifilm cameras, which are likely coming within the next handful of months, that they overhaul Advanced Filters. Fujifilm is probably not doing this, but let’s just pretend that they are (because they should). Let’s say that Pop Color is gone because it’s now the Fortia Film Simulation. Let’s also say that High Key and Low Key are removed because they are unnecessary and their inclusion is a bit silly. Additionally, let’s say that Dynamic Tone and Soft Focus are axed because they’re cringy. That leaves Toy Camera, Miniature, and Partial Color, which Fujifilm should allow customization for, so that they can be modified for each person’s tastes.

Obviously, some new Advanced Filters will need to be added to replaced the ones that were removed. Fujifilm needs to look no further than the X half to find the answer. The Fujifilm X half has Filters, which are the Advanced Filters plus some new ones taken from the Instax Evo series. Some of these are really good, and should make their way into other X-series cameras. Let’s look at a few that Fujifilm should add to Advanced Filters.

Retro

The best that I can describe the Retro Filter is push-processed Ektachrome slide film from the late 1960’s and 1970’s (think Ormond Gigli’s color work from that era). This is one of my favorite X half filters, and would be a great addition to the X-series.

Expired Film

The Expired Film Filter on the X half has three options: Green, Red, and Neutral. These aren’t Filters that I would use all the time, but on occasion they can be a lot of fun. As long as Grain can be selected (or maybe Fujifilm has Grain built into it), then it doesn’t need to be customized any further.

Light Leak & Halation

Above left: Light Leak Filter; Above right: Halation filter

There are two other X half Filters that I would like to see added to the X-series: Light Leak and Halation; however, I would like these to be JPEG options and not stand-alone Advanced Filters. You should be able to apply them to any Film Simulation, and make them a part of Fujifilm Recipes. For Light Leak, the options should be: Low, High, On, Off. If set to On, every image has a light leak; if set to Low, only a small percentage of random images (say 5%) get a light leak; if set to High, a larger percentage of random images (say 20%) get a light leak. The Halation effect, which should have the options of Off, Weak, and Strong, would be great for Cinestill Recipes. If Fujifilm is unwilling to do that, at the very least they should add these two to Advanced Filters.

Cross Process

This is a bonus, but I think an Advanced Filter that resembles cross-processed Fujichrome Velvia 50 film would be really cool. I used to develop E6 slide film in C41 chemistry for fun many years ago, and if my Fujifilm camera could replicate that aesthetic, I would love it.

If Fujifilm asked for my input on how to improve the Advanced Filters, I would get rid of a few of them (namely, High Key, Low Key, Dynamic Tone, and Soft Focus). I would graduate Pop Color to a Film Simulation named Fortia. I would allow Toy Camera, Miniature, and Partial Color to be customized with various JPEG options. I would add Retro and Expired Film from the X half to the list of Advanced Filters, as well as Light Leak and Halation if Fujifilm is unwilling to make them JPEG options that can be applied to any Film Simulation. And I would add a Cross Process Advance Filter that resembles Fujichrome Velvia 50 developed in C41 chemistry, because that would be really cool. This would turn what is often viewed as a cringy feature into something more useful and better appreciated. Will Fujifilm take this advice? I hope so, but my guess is that Advanced Filters will continue to be identical to what it was way back in 2013 when it was first introduced.

Fujifilm should add these X half features to the X-series

Posted on May 31, 2025 by Ritchie Roesch

I got a surprise package in the mail from Fujifilm: the brand-new X half! I will write a review of the camera in a few weeks probably—I haven’t had it nearly long enough to provide any proper insights. It’s a fun little camera, with some positive and negative aspects. We’ll talk about all of that at some point in the future. Today I want to write about how Fujifilm could implement some features of this camera into future X-series models.

Specifically, I want to discuss a few of the new Filters. Filters are not Film Simulations (although some of them are based on Provia); on all other X-series models, these are known as Advanced Filters. The X half has the usual array: Toy Camera, Miniature Effect, Pop Color, High-Key, Low-Key, Dynamic Tone, Soft Focus, and Partial Color. There are also some new ones, that apparently are borrowed from the Instax Evo line: Canvas, Retro, Vignette, Blur, Fisheye, Color Shift, Mirror, Double Exposure, Light Leak, Halation, and Expired Film. Some of these are uninteresting, and probably should have been left off the camera so that one could navigate the menu faster. But some of these are great, and should be included in future X-series models—just maybe not in the same way.

My favorite is Light Leak. With this filter, the camera puts a random faux light leak on your images. You don’t know what you’re going to get, and that serendipity can be thrilling, especially when it just really works with the image. I would love Light Leak to become a JPEG option (like Color Chrome Effect and Grain) on all X-series cameras moving forward. You should have three choices: All (where every picture gets a light leak), Random (where some pictures get it, but most don’t), or Off (for those who don’t want it at all). This would be such a fun thing for Fujifilm to add, and it seems like it wouldn’t be very difficult to do.

Next up is Expired Film, which has three options: Green, Red, and Neutral. This should be a new Advanced Filter on future X-series cameras. On the X half, your Grain settings get applied to the Filters (at least some of them; I haven’t tested them all yet), and not just the Film Simulations; however, on the X-series, you can’t apply Grain to the Advanced Filters. So this is actually two suggestions for Fujifilm: add Expired Film to Advanced Filters, and allow Grain to be selected for Advanced Filters.

Third is Halation, which puts a red glow around bright highlights. This Filter should be a JPEG option that can be applied to any Film Simulation. I suggest three choices: Off, Weak, Strong. I would love to pair this effect with my CineStill 800T Recipe to more accurately mimic the film. The X half is not necessarily a great option for nighttime photography, so it’s almost a waste on this camera, but I definitely see potential for this effect on other X-series models.

I haven’t used Retro yet, but I’m sure it would be fine to join the Advanced Filter club. Vignette should probably be added as a JPEG option (like Color Chrome Effect and Grain). In my opinion, Fujifilm should graduate Pop Color to Film Simulation, and call it Fortia. In-camera diptychs are just a ton of fun, but I don’t see that coming to other cameras. The Film Camera Mode is pretty cool, and I’d like to see something similar be included in the next X-Pro or X100-series model (although maybe implemented slightly differently). The X half has plenty of unique features and functions, which is what makes it an interesting camera. In my opinion, some of these need to find their way into other models, and not remain solely on the X half.

How To Add “Light Leaks” To Your Photos Using Page Markers

Posted on December 9, 2018 by Ritchie Roesch

I much prefer to create a look in-camera than to use software to achieve it. I’m a big fan of avoiding post-processing whenever I can because I don’t like sitting in front of a computer anymore than I absolutely have to. Sometimes it’s not possible to achieve my photographic vision without editing, but most of the time with a little care I can get the exact look I want straight out of the camera. Whenever I find a trick that might help me get in-camera the results I want, I’m willing to give it a try.

Recently I came across an article where photographer Maciej Pietuszynski used colorful sticky page markers, also sometimes called popup index tabs, to create light leak effects without software. Stick the colorful page markers in front of the lens and watch the magic happen! It works quite well and is surprisingly convincing.

In the film days, light leaks would happen when a camera became worn or damaged. When the seal that keeps the inside of the camera completely pitch black is compromised, unwanted light enters and exposes the film. If film isn’t handled correctly during development, it’s also possible to get light leaks that way. The two pictures below are examples of light leaks that I have experienced.

Light leaks come in all sorts of colors and shapes. They’re not typically uniform. Some people love them and some people hate them. There are some photographers who actually seek out cameras that leak light, and even a few who will purposefully damage a camera in order to create light leaks. There was even a 35mm film that was produced that had light leaks already on it, so that you could get the effect with a camera that wasn’t damaged.

In the digital world, you can mimic the light leak effect using software, which is something that I occasionally did using Alien Skin Exposure (I haven’t done this in several years). Using a faux light leak is fun every once in awhile, and it works well for certain images, but it can seem kind of gimmicky if you apply it too often. Below are two pictures of mine that include fake light leaks using software.

Using page markers is a good technique to achieve a light leak effect without using software. I played around with it on my Fujifilm XF10 over the last two days, and I was able to get some interesting results that did in fact resemble light leaks. In my opinion, it made the images look a little more analog. In the pictures where the effect is really subtle, it gives the images a slight atmospheric feel that is still intriguing. I don’t think this something I’d want to do all of the time, but in the right situations it can be effective. At the very least it’s a fun technique to experiment with. It’s very lomography in spirit.

If you find yourself bored on a Saturday morning or you just want to try a new technique to produce a more analog-like result, I invite you to give the page marker light leak trick a try. It’s something that you could file away for use at some later time when you have a certain look in mind, or maybe you’ll find it to be useful in your regular workflow. Below are photographs that I have captured using this technique.
