How to create color profiles with ART filters

Last updated:- 15th July 2025

It's good to see the enthusiasm for creative color, ART filters, and profiles among photographers with the Pen F, E-P7, and OM-3. I've never seen such a surge of positive feedback about ART filters and the various Olympus color options as I have in the past six months. It's remarkable to think that Olympus first introduced ART filters with the E-30 in 2008. The Pen F subsequently became a sought-after camera for creative and street photographers, and by 2025, the Olympus E-P7, Workspace, and the Ol.Share app continue to be a popular choice for hobby and creative photographers.

Tip: The images in this article is best viewed on a large display.



I had never thought of Olympus ART filters as a way to craft distinctive and vibrant profiles. While I was aware of the enhancements added to the E-P7, I overlooked the extra flexibility that comes with adjusting ART filters, both in-camera and with Workspace. The more I explore Olympus cameras and Workspace, the more I appreciate the incredible capabilities of these amazing M43 products.

Photographers can adjust nine of the thirty ART filters with the E-P7. With the Pen F and the OM-3 it's none, and with the EM10 IV it's two. Both the E-P7 and OM-3 enhanced raw files have access to all nine adjustments in Workspace. All JPEG and TIFF files have access to these adjustments.

Tonal adjustments are an excellent editing choice for cameras that do not have the new ART filter function. Unlike the Pen F, E-P7, and OM-3 models, Workspace let us blend ART filters with color adjustments. For example, successfully editing watercolor ART filters involves tonal adjustments to create white and black backgrounds, along with fine-tuning colors with the Adjust Color tool.

See this article for more about the exposure mix versus tonal adjustments.

See this article for more about Workspace.



If you've been reading my blog for a while, you know that I encourage photographers to develop their own profiles. Workspace is crucial for learning more about creative color, ART filters, the Color Creator, and how to create color profiles. The camera display is too small for this kind of editing. It's much simpler to apply proven editing techniques directly to the camera while shooting.

While I enjoyed Photoshop, I cancelled my subscription because the renewal was just too expensive. I tried a number of editing software options in an effort to replace Photoshop. I decided to get and focus on Affinity Photo 2 in the future. While evaluating other editing options, I was lost in all the profiles, LUTs, presets, and whatever AI options developers have on offer. I can do everything I need with Workspace, and like Photoshop, Affinity Photo offers me that little extra.



Each image featuring an ART filter in this article has been edited with Workspace. Some were done with the new ART filter adjustment, and others with effects and tonal adjustments. Olympus and OM System photographers enjoy much freedom while expressing their creativity with ART filters.

I often wonder how much enthusiasm it would have taken for Olympus to expand their creative offer. How will creative photographers and younger generations apply and tweak these ART filters?

The 8 nuances influencing your exposure mix

Last updated:- 14th July 2025

The subtle benefits of an inclusive approach to assessing the unique nuances impacting our digital exposure mix are overshadowed by marketing initiatives, the transition from analog to digital, and the commercial focus on the camera's image sensor. A fundamental analysis of theoretical principles revealed that the emphasis on the image sensor often overshadows the benefits of a more inclusive approach to creating the right exposure mix, the digital imaging process, and how we utilize these exposure and tonal nuances to improve our digital photography and overall experience.

Update: I didn't expect this article to receive so many views. Thank you.



Most photographers are introduced to digital photography through the lens of the exposure triangle, which defines the aperture, shutter speed, and ISO. Photographers are generally advised to keep the ISO value low, as higher "sensor sensitivities" could lead to unwanted image noise. The aperture and shutter speed ratio not only influence the exposure mix, they also guide optical effects such as depth of field, while varying shutter speeds express movement in the scene. 



This mainstream view of the exposure triangle gave modern marketers a significant advantage. For instance, would you classify the exposure triangle as leaning more towards analog or digital cameras? It is worth considering that modern marketing campaigns tend to include elements of truth while omitting critical details. The illustration below offers photographers a more detailed overview of the exposure nuances and digital processing of the image signal inside the digital camera.



Figure 1.

Most digital photographers are familiar with the journey of mastering the dual purpose of the shutter and aperture mix. Achieving the perfect exposure mix includes optical effects such as background blur or the interpretation of moving objects, which demands both experience and regular practice to eventually become a natural routine. You may be surprised at how quickly one learns to add sensor and gamma controls to this traditional process of finding the ideal exposure and tonal mix.


The 8 unspoken nuances impacting your camera's exposure mix:
  1. There is way more to the camera's sensor than its diagonal measurement.
  2. Each digital camera (sensor) has unique technical and optical limitations.
  3. We use the aperture and shutter to expose and saturate the image sensor.
  4. The ISO amplifies the image signal; it does not adjust sensor sensitivity.
  5. It's crucial to master technical aspects like saturating the sensor and SNR.
  6. Consider and manage the 4th exposure variable; Average scene luminance.
  7. Managing the camera's sensor maximizes dynamic range and image noise.
  8. The unique differences between the exposure mix and tonal adjustments.


I converted/edited this EM5 II enhanced raw file in Workspace. I used tonal adjustments to finalize the look.


The above flow diagram (Fig. 1) illustrates the image signal path from the lens to the final JPEG. My advice is to familiarize yourself with this illustration. The following points are helpful:
  • The shutter and aperture control the reflected light to the sensor.
  • We manage the avg. scene luminance with a flash or the time of day.
  • The ISO amplifies the image signal and noise from the image sensor.
  • The TruePic image processor manages the image creation process.
  • The gamma curve converts the linear sensor data to a human format.
  • The gamma Gradation feature also controls the exposure controller.
  • The enhanced raw format links the TruePic processor to Workspace.
  • We use a fixed ISO to monitor/control the reflected light to the sensor.
  • Fixing the ISO means the histogram shows shutter and aperture values.




A basic version of this Olympus know-how applies to all digital cameras. For instance, similar to the Olympus gradation function, Fuji has DR100, DR200, and DR400, and Canon has the Auto Lighting Optimizer. Tonal or gamma controls include shadows, highlights, and midtone adjustments, plus the tone curve option of Workspace. For more in-depth articles on these topics, refer to this link.

Workspace is a great RAW converter for the Olympus photographer. It has a full range of raw controls and is one of the best options to familiarize yourself with the enhanced raw format. I also prefer the AI noise filter of Workspace (WS) when possible. Please take note that while Workspace will show no clipping, other raw converters seem overly eager to highlight "overexposed" areas.



Study my articles on exposure and the photons-to-electrons graph and how we apply this knowledge to control the sensor's saturation and signal-to-noise ratio (SNR). The photons-to-electrons graph also has more info about the sensor's noise floor and how we plan/control noise and dynamic range.


In the past, I stated that this know-how is enough to significantly improvement your digital results. I often reflect on that assertion and wonder if I may have been overly optimistic. As I experimented with high dynamic range scenes for this article, I was reminded of how quickly these new sensor and tonal considerations became an instinctive part of determining my final exposure mix.


I'd like to offer some general tips to enhance your digital photography experience. One key piece of advice is to steer away from forums and camera reviews, as they tend to become echo chambers that primarily advocate for cameras with larger sensors. This emphasis on the sensor can create the perception that the image sensor is solely responsible for the digital image creation process.

I plan the processing of my raw files while setting my camera's exposure mix. This includes tweaking my exposure with the exposure compensation slider in the camera and Workspace. This is followed by tonal and color tweaks, including image contrast and sharpness with the tone curve function. The primary goal of tonal adjustments is to highlight the natural lighting variations in the scene.


I converted this EM5 II raw file in PhotoLab 7.


Many photographers underestimate the depth of field advantage of M43 cameras. Selecting the right aperture/focusing ratio is often enough to gain two or more stops with the final exposure mix. This gain simply relates to more control over dynamic range, noise, and the recorded tonal data.

Here are the general steps I follow to set and finalize my exposure mix:
  • I mainly use Aperture or Shutter Mode with a fixed ISO.
  • Learn how to leverage the DOF benefit of M43 cameras.
  • Use IBIS to benefit your shutter/aperture exposure mix.
  • This does not mean not selecting the right shutter speed.
  • Select the right focus point to extend the in-focus area.
  • Practice how to gain 1 to 2 stops without upping the ISO.
  • Study this article for more about the Gradation function.
  • My final camera exposure settings are 98% optimized.
  • This includes specific gradation options for the camera.
  • That means I do only small exposure corrections in WS.
  • With practice this quickly becomes a natural process...

Exposure settings and tonal adjustments are two different things. The Gradation function does have a link to the camera's exposure controller, which lets us use the gradation function to alter the camera's gamma curve and to control clipping. Tonal adjustments like shadows, midtones, highlights, and the tone curve function in Workspace let us paint with light or tweak the scene's natural lighting.




Those relying on the sensor need tonal adjustments to "recover" clipped highlights and shadows, whereas those with knowledge about digital cameras apply framing, all four exposure variables, and tonal adjustments. For instance, how do we enhance low-light or shadow information?

How does one know if tonal adjustments change my exposure or tonal values? For instance, why does the Gradation function only change the tonal curve when applied in Workspace?


A final image from the Olympus EM5 II with the M.Zuiko 25mm f1.8 lens. I converted the enhanced raw file in Workspace.


The average dynamic range and noise differences between digital cameras are one to two stops. As one gains experience, it becomes evident that the ongoing sensor debate overshadows the crucial roles of the camera, the lens, the sensor, the image processor (firmware), and the photographer in establishing and leveraging the exposure and tonal mix to maximize the recorded image data.

In conclusion, you may be surprised to learn that awareness and experience are enough to make this knowledge work for you. Take, for instance, fixing the ISO to track what's happening at the sensor. In daylight photography, the Auto ISO value usually remains at its minimum setting (referred to as “fixed” auto). This simply means one will manage shadows and low-light situations differently. Why do we see more noise in shadow areas? Study the photons-to-electrons graph for answers.

Having fun with the original Olympus EM1

Last Update:- 12th June 2025

Given social media statements and a general focus on sensor size, one would question my enthusiasm for an M43 camera released in 2013The Olympus E-M1, which remains a remarkable camera in 2025, highlights this distinction. While preparing this article, the E-M1 reminded me why Olympus cameras became so popular. By adopting a philosophy that diverged from the trend of prioritizing the sensor, Olympus acknowledged that all sensors are subject to optical and technical limitations. This mindset empowered the Olympus engineers to develop more innovative solutions to effectively address and leverage these inherent sensor limitations and qualities (strengths and weaknesses).

This article reviews these technical versus optical limitations.




Image noise amplifies the significance of acknowledging the distinction between the sensor's optical and technical attributes. Social media experts often advocate for FF cameras as a quick remedy for noise. Olympus opted to create more efficient solutions because they recognized that all sensors have a noise floor. For example, I rarely need third-party AI noise filters for my Olympus RAW files because knowledge combined with the standard and AI noise filters from Olympus are good enough.


I converted the enhanced raw file in Workspace. The E-M1 has excellent IQ with a natural balance between an analog feel, color, and detail.


In-body image stabilization (IBIS) illustrates how Olympus became a market leader in navigating the technical challenges associated with image sensors. For instance, photographers can achieve up to a 2-stop noise improvement with IBIS and the depth-of-field advantage of M43 cameras. This simply means upping the sensor's saturation and a higher signal-to-noise ratio (SNR). Computational features offer similar benefits. Old-school options, like a tripod let us position the camera more accurately, control camera movement (zoom lenses), and/or increase the reflected light to the sensor.

These basics help us when photographing with cameras like the E-M1, because the E-M1 sensor does have a larger noise floor with more visible noise at lower SNRs when compared to the sensors in the OM-1 and E-M1 III. I used the camera's "Low" Noise Filter for all the photos in this article.

This article merely touches on the creative potential photographers enjoy with an Olympus E-M1. It is remarkable that a small M43 camera from 2013 delivers such beautiful photos at current used rates. Notably, many may not know that the Olympus E-M1 received its final firmware update in 2019 and already offered computational features in 2013. I will outline some features that could enhance your macro photography, as well as the photography styles showcased in this article.



The following features are unique to the Olympus E-M1:

  • Top-down EVF option - this is unique to Olympus M43 cameras with an accessory port.
  • The macro arm LEDs (MAL-1) is unique to Olympus cameras with an accessory port.
  • The Photo Story feature of the Olympus E-M1. See the final two photo examples.

Features common to most Olympus M43 cameras:

  • ART filters (Several examples were done with ART filters)
  • Color Creator (I used the Color Creator with some images)
  • 2X Digital Zoom at full resolution
  • Color profiles (Adjust color function)
  • Black and White or Monochrome options
  • Focus Stacking with the E-M1, Photoshop, or Workspace
  • LIVE Composite (Painting with light)
  • LIVE Time
  • Flash remote control (RC)
  • Live View Boost
  • S-OVF
  • Exposure Shift
  • Selective AE and AF options
  • 2 second timer
  • Video



Olympus designed Workspace and the enhanced RAW format as unique enablers for Olympus M43 photographers. They encourage more image and creative control by letting photographers tweak their camera settings when converting Olympus RAW files or editing JPEGs on personal computers. Older M43 cameras like the Olympus E-M1 and E-M5 II share a unique advantage when shifting from a sensor size focus to a more hands-on or practical approach to digital photography.

The original Olympus E-M1 does have a quality concern. Early production runs of the E-M1 had issues with the control dials, leading to failures. In response, Olympus issued a formal notification and provided complimentary replacements for the affected dials. Unfortunately, not all E-M1 owners took advantage of this repair offer. Therefore, it is advisable to verify the status of any used E-M1 dials before purchasing. Additionally, updating the firmware is recommended, as it unlocks more features and functionality. See this article for more on firmware updates.




What is the most important lesson we learn from photographing with the E-M1? Older cameras like the E-P3 or the E-M1 reveal that the notion of achieving perfect image quality is a myth. For instance, when using the E-M1, technical aspects such as dynamic range, noise, and image quality often took a backseat in the creative process. Instead, I found joy in leveraging the E-M1's technical limitations to better express my artistic vision. This approach invites contemplation on the creative possibilities that can emerge when we adopt a similar mindset across all types of cameras.
