7 Film Simulation Recipes for Ultra-High-ISO Photography

*Garden Spiderweb* – Buckeye, AZ – Fujifilm X-E4 – GAF 500 Recipe – ISO 12800

I remember when ISO 400 used to be consider high ISO. In fact, the “H” in Fujicolor Pro 400H means high ISO. When I shot film, I usually didn’t go higher than ISO 400, although on a rare occasion I did go wild and use an ISO 800, 1600, or (gasp!) 3200 emulsion (those were ultra-high-ISOs back then), when the expected light was dim and a tripod wasn’t practical. When I started shooting digital almost 15 years ago, I remember that ISO 1600 on my first DSLR was barely usable in a pinch, and it was best to stay at or below ISO 800. Nowadays those limitations are long gone.

Thanks to the X-Trans color array, Fujifilm is better able to differentiate color noise from color information (than with a Bayer array), allowing more control over how noise is rendered. Because of this, the APS-C sensor on Fujifilm X cameras does pretty darn well at high-ISO photography. Yes, it can get noisy, but the noise is more organic-looking and less color-splotchy (perhaps even a little film-grain-like) than non-X-Trans cameras typically produce.

Still, a lot of photographers are hesitant to try high-ISO photography. I’ve had someone tell me that they never go beyond ISO 800 on their Fujifilm cameras. Someone else said that they don’t use Film Simulation Recipes with DR400 because it requires an ISO that they’re not comfortable using. Everyone has their own preferred upper ISO limit—mine might be higher than yours, and that’s ok. What I’d like to do, though, is encourage you to step outside of your comfort zone, and try some ISOs that you would not normally—or perhaps ever—use.

You might want to use ultra-high-ISOs—which I consider to be ISO 12800 and higher, but your definition might be different—in dim light situations, such as at night or in a poorly lit room. That’s probably the most common reason. I will sometimes use really high ISOs in daylight when it’s not even necessary just for the aesthetic of it. Crazy, right?! I think sometimes digital can appear too clean, and an ultra-high-ISO can give the picture a grittier look, more similar to some film emulsions.

Of course, using ultra-high-ISOs in daylight can be problematic because the light is strong. My Fujifilm X100V has a built-in ND filter, which makes it more practical. Otherwise, screwing an ND filter onto the end of the lens will help. If you don’t have one, be sure to use your camera’s electronic shutter (instead of the mechanical one) because it is capable of faster shutter speeds. You might also have to use small apertures like f/11 or f/16 to reduce the light entering the camera.

If you want to give it a try, below are seven Film Simulation Recipes that use ultra-high-ISOs. Many of them go “up to” an ultra-high-ISO, so in that case you’d want to purposefully choose a high ISO instead of a low one. Give one or more of these Recipes a try today! Leave a comment to let me know which one (or ones) you like. My personal top favorites are GAF 500 for color and Kodak Tri-X 400 for B&W.

Making the Fujifilm X-T5 Make a Lot of Noise — Testing High-ISO on X-Trans V

Posted on November 28 by Ritchie Roesch

*Lights from a Frosted Window* – Williams, AZ – Fujifilm X-T5 – “Kodachrome 64” – ISO 6400

A lot of people have asked me if the Fujifilm X-T5, with the new 40-megapixel X-Trans V sensor and processor, is better or worse than the 26-megapixel X-Trans IV cameras when it comes to high-ISO noise. Conventional wisdom would suggest that the lower-resolution sensor would be superior. Is it? Or did Fujifilm pull a rabbit out of a magic hat and somehow make X-Trans V better at high-ISO despite more megapixels?

I’ve spent some time pixel-peeping, comparing X-Trans V to X-Trans IV. Right off the bat I can tell you that both are pretty similar to each other. You’ll have a very hard time noticing the differences without pixel-peeping, and with pixel-peeping, they’re still quite similar. Below I’ve included a massive crop from an X-Trans V camera and an X-Trans IV camera. If these crops were sections of the whole pictures printed, I don’t know how large the prints would be, but they would be very large, so keep that in mind. The picture on the left (revealed by moving the bar to the right) is X-Trans IV, and the picture on the right (revealed by moving the bar to the left) is X-Trans V. Take a look at these two images.

You likely notice that the X-Trans V image is a little more detailed with noticeably finer digital noise, while the X-Trans IV picture is a tad fuzzier with chunkier digital noise. This is a result of the higher resolution sensor of the 40mp X-Trans V camera. What might be less obvious is that there seems to be just a bit more color blotchiness in the X-Trans V image. Perhaps even less obvious, I believe the X-Trans V camera is applying a slightly heavier-handed noise reduction to the picture than X-Trans IV, despite both set to -4 High ISO NR. However, please take all of this with a grain of salt, because we’re seriously pixel-peeping here. In real world photography, both cameras are pretty darn good at high-ISO, and neither are significantly better or worse than the other, and there’s no practical variance between the two. Unless you print posters or crop deeply, you’re not going to even notice a difference—even if you did print large or crop massively, the differences are pretty minor, but I guess you can feel confident that ultra-high ISO pictures will look slightly better (for the most part) on X-Trans V than X-Trans IV. That’s the takeaway, I think: high-ISO on X-Trans V cameras are just a hair better than X-Trans IV, but not enough to make a practical difference for most people. What I will add, though, is that it’s pretty amazing that they could do this while also increasing the resolution. I do wonder, though, if Fujifilm could make—say—a 20mp X-Trans camera with significantly increased dynamic range and high-ISO performance—that’s something I would be highly interested in.

Below are a few more high-ISO examples from my Fujifilm X-T5 camera.

When Does ISO Matter?

Posted on January 12, 2019 by Ritchie Roesch

Modern cameras have amazing high-ISO capabilities. Back in the days of film, ISO 400 was considered high-ISO by many (including Fujifilm, who designated all their ISO 400 films with the letter “H” for high-speed), and ISO 1600 was ultra-high-ISO, used only out of absolute necessity or by the brave who wanted a certain gritty look. Nowadays some photographers don’t even think of ISO 1600 as a high-ISO setting, and don’t think twice about using it. For many, high-ISO doesn’t really begin until ISO 3200, and ultra-high-ISO doesn’t begin until you go above ISO 6400. It’s really unbelievable!

The real question is this: when does ISO matter? Since modern cameras make such good-looking images at incredibly high sensitivities, when should you start considering image quality degradation? When is a certain ISO setting too high? That’s what I want to answer.

Of course, since this is the Fuji X Weekly blog, I’m discussing Fujifilm X cameras, specifically X-Trans III. This won’t apply 100% to other cameras, but it’s still relevant to some degree no matter the camera make and model. If you are reading this with another camera in mind, take everything said here with a small grain of salt.

I did a little experiment just to better understand all of this ISO stuff. I already knew the answer from experience even before beginning the experiment, but I wanted to see if my instincts matched reality. I captured a few sets of identical pictures, all straight-out-of-camera JPEGs from a Fujifilm X-T20, using ISO 400 and ISO 6400. I made sure that all of the settings were the same between the identical pictures except for ISO and shutter speed. This isn’t 100% scientific, but it’s a controlled-enough test to draw some conclusions about ISO capabilities.

Here are the original pictures:

ISO 400 – my Ektachrome 100SW recipe

ISO 6400

ISO 400 – my Velvia recipe

ISO 6400

ISO 400 – my Acros Push-Process recipe

ISO 6400

There’s not a lot that can be learned by looking at the above images, other than when viewing images on the web the ISO doesn’t matter whatsoever because it’s incredibly difficult to spot the differences even when comparing side-by-side. In real life nobody does side-by-side comparisons, that’s pretty much an internet-only thing, so it would be impossible to tell if a picture was captured using a low-ISO or high-ISO just by looking at it on your screen. We need to look much closer to really gain anything from this test. Below are some crops from the above images.

If you study the color crops carefully, you’ll notice that the ISO 400 images are cleaner, sharper and have just a hair more dynamic range, but the differences are quite small and subtle. You really have to look carefully to find them. With the black-and-white image, the differences are even less obvious, and I actually prefer the ISO 6400 version, as it seems to have a more film-like quality. Looking at the crops clarifies things a little, but what kind of conclusions can we really draw?

My opinion with regards to color photography and ISO is this: if I’m printing smaller than 16″ x 24″ or displaying the pictures on the web, I don’t find any practical difference between base ISO and ISO 6400. Even ISO 12800 can be acceptable, especially if I’m not going to print the picture. If I’m going to print 16″ x 24″ or larger, a lower ISO is better, preferably less than ISO 3200, but it’s not a big deal to use up to ISO 6400. The ISO that I select does not make a huge difference to the outcome of the image, so I don’t worry a whole lot about it. Put more simply, if I print large, it’s preferable but not critical that I use a lower ISO, and if I don’t print large it doesn’t matter at all.

My opinion with regards to black-and-white photography and ISO is this: the ISO doesn’t matter much at all no matter how large I’m printing, and I often prefer (just by a little) high-ISO over low-ISO because it looks more analog. I freely use without hesitation any ISO up to 12800. Thanks to the Acros film simulation, Fujifilm X cameras are some of the best monochrome cameras on the market, and with that film simulation, often times the higher the ISO the better.

These are, of course, my opinions, and not everyone is going to agree with them, and that’s perfectly alright. Find what works for you. Use a higher ISO or lower ISO if that’s what you need for your pictures, because, after all, they’re your pictures. I’m not here to judge your camera setting choices, only to offer mine, which I’m hoping is helpful to some of you. I hope that this article makes sense and clarifies some things regarding high-ISO on Fujifilm X cameras.
