Talk to Rico (questions & feedback) – X20 sample images set – X20/X10 comparison images set

So you have pulled the trigger on a new X20? Let’s compile a few tips and tricks to get you started!

Auto-ISO

The X20 has a new Auto-ISO function that is based on the classic X100 and mimics the functionality of the new X100S. In Auto-ISO, you can set the ISO base (minimum ISO / default sensitivity), the ISO limit (maximum ISO sensitivity) and the minimum shutter speed. These settings can also be saved in different customer profiles (C1 and C2).

If you plan to use the DR (dynamic range) function (DR Auto, DR200% or DR400%) you should set the camera to Auto-ISO. Unlike the X10 with its EXR sensor, the X20 needs to raise the ISO sensitivity to a minimum of ISO 200 for DR200% and ISO 400 for DR400%. You can read this X-Pert Corner article to learn more about how to expand dynamic range.

Auto-ISO’s minimum shutter speed can be augmented by the optical image stabilizer (OIS) of the X20 when you set the OIS to one of its two “motion” modes. In these modes, the camera will scan the scene for motion and crank up the shutter speed (and along with it the ISO setting) accordingly. Of course, the camera can only do this when Auto-ISO is active. For example, my X20 chose ISO 400 and 1/320s (instead of ISO 100 and a slower shutter speed) when I shot these horses trotting directly towards the camera:

Once the horses had come to a stop, I took another pic, but this time, the camera reverted back to ISO 100 and a more moderate shutter speed of 1/150s:

Aperture was kept at f/5.0. Both shots were taken in Aperture priority (A) mode.

Since pretty much everybody wrote about Lightroom 4.4RC in the past few days, I won’t. After all, what’s the big story? It took Adobe a full year to get their paying customers what the free RAW File Converter EX software and Fuji’s internal JPEG engine delivered from day one: decent X-Trans demosaicing quality. Big deal! But for those who are still interested in LR4.4RC, I have updated my RAW converter comparison set on Flickr with several new renderings.

Let’s take a look at colors, so-called “Fuji Colors” in particular. It’s often noted that Fujifilm’s built-in JPEG engine is one of the best in the entire industry. Obviously, people either love it, hate it or are just plain ignorant about it, but if you belong to the “I love it” crowd, there’s a good chance that “Fuji Colors” have played a role when you made your decision to buy an X-series camera.

The heart of these colors are the different film simulations Fuji’s cameras are offering in either the shooting menu or in the camera’s internal RAW converter. X-Trans sensor cameras feature five different color film modes, named after famous analog slide and negative FUJIFILM brands: Provia, Astia, Velvia, Pro Neg. Std and Pro Neg. Hi. Make no mistake: These aren’t accurate recreations of analog films. Instead, you get modern, state-of-the art color gradations that feature key qualities of their vintage role models: Provia is a more-or-less neutral all-purpose film mode, Astia delivers more distinct “Fuji Colors” with added pop in the shadows and smooth highlights, while Velvia offers high-contrast JPEGs with strong, saturated colors. Pro Neg. Std and Hi deliver accurate and pleasant skin tones, with “Std” acting as the neutral option and “Hi” as the one giving additional pop and contrast.

Here’s a practical example illustrating the five different film simulation modes:

This example was shot with an X-Pro1 and the Fujinon XF 60mm Macro prime lens at f/4.0, 1/480s and ISO 200. The top row is showing Provia, Astia and Velvia, the bottom row shows Pro Neg. Std, Pro Neg. Hi and a Lightroom development that looks like something in-between Provia and Pro Neg. Std. You can click on the image for a hi-res view, but even if you don’t, you can clearly see that Fuji’s different film modes can deliver quite distinct results. Remember, this is all the same shot, just developed with different film simulation modes in the camera’s internal RAW converter (aka JPEG engine).

Let’s decide for Astia at this time, as it offers a very distinct purple-red rendering of the flower, with smooth highlights and nice contrast in the darker shadows. A typical problem of mono-colored subjects like this one are overflowing RGB color channels, in this case the red color channel. Here’s a magnified view of our Astia shot, showing three different color saturation level settings that can be applied either in the shooting menu or when (re-)developing the RAW file in-camera:

The color settings used here were -2 (left), 0 (center) and +2 (right). Clearly, too much color saturation in the reds goes at the cost of image detail, so we are better off using a saturation setting of -2 (aka “low” when you are using the internal RAW converter). Here’s the less color saturated Astia JPEG of this shot, straight from the camera’s built-in RAW converter:

As usual, click on the image for a full-size view. This was a hand-held macro shot, so I used the smallest available AF field size and moved it precisely over the area I wanted to be in-focus.

So far, so good. We now have an image with quite distinct “Fuji Colors”. Some people may like it, some may not, it doesn’t matter. What matters is that many of those who like their own JPEGs with Fuji colors would often also like to achieve similar looking results with external third-party RAW converters like Silkypix or the free RAW File Converter EX (which is an older version 3 of Silkypix).

How can we do it? Let’s play it through! Here’s the RAW file as it looks in Silkypix 5 with the software’s default settings:

Uh-oh! While this default rendering proves that claims about X-Trans sensors being incapable of delivering saturated reds are wrong, this is obviously not the result that we had in mind. In order to emulate the Astia rendering of the in-camera JPEG engine, we need to make some changes. But there’s more! If you click on this image for a full-size view, you will see ugly artifacts in the deep reds, almost like dirt soiling the colors of the flower. Here’s a zoomed-in view of this phenomenon, just click on it to see it in full size:

This doesn’t look nice, not to mention that the red is somewhat over-saturated and obscuring image details. So let’s correct this, shall we? After a few modifications in Silkypix, the image looks like this:

To make the comparison a little easier for you, here’s the original Astia JPEG again:

It’s not exactly the same, but it’s close enough for me. Of course, you could achieve a perfect match with a few further adjustments in Photoshop, Lightroom, Aperture or any other powerful image editor, but maybe an exact match wouldn’t really improve the image, anyway? Also note that the “dirt” and other color artifacts in the red flower are now gone.

So what exactly did I do to make it work?
Well, buy my next book to find out.
Good night, and good luck!

…and JPEG for RAW Shooters!

by Rico Pfirstinger

One of the most persistent flame wars on the “photographic Internet” is the endless fight between RAW and JPEG shooters. If it wasn’t so sad, it would be funny. Readers of my book know that I prefer a comprehensive approach to this hot topic by advising to shoot FINE+RAW (SHOOTING MENU > IMAGE QUALITY) at any time, no matter whether you consider yourself a part of the RAW or JPEG camp. There are plenty of good reasons for being inclusive instead of divisive.

Why “RAW only” shooters should use FINE+RAW

Even if you consider yourself a hardened “RAW only” shooter, FINE+RAW makes sense for you. Don’t forget that you can preview exposures on your camera only in JPEG format. This means that even in “RAW only” mode, your camera will produce a JPEG out of every RAW file it saves to provide you with a preview file. Otherwise there wouldn’t be anything to examine in playback mode.

However, these preview JPEGs in “RAW only” mode are low resolution—often so low that it is impossible to tell whether image details are in focus when you zoom-in to 100%. Shooting in FINE+RAW mode with an IMAGE SIZE of L obviates this problem. With this setting, the camera saves a high-resolution JPEG “print” in addition to the RAW “negative”: You can use this high-res JPEG for precise focus control immediately after you snap it by pressing the command dial, thereby enabling the 100% zoom function. Moreover, the high-res JPEG file is a good point of reference for developing the RAW file later in your personal computer.

Admittedly, you could also opt to shoot in NORMAL+RAW mode instead of FINE+RAW, which doesn’t actually affect the resolution of the JPEG. However, this setting produces files with greater compression, compromising image quality. Dedicated RAW shooters should pay attention to this fact, because in some modes, the camera saves only JPEGs without any RAW files! Think of motion panorama or of ISO, film simulation and dynamic range bracketing as examples for such modes. In all these cases, your X-Pro1 or X-E1 (or X100 and X100S) silently switch the image quality setting from NORMAL+RAW to NORMAL, which means the only image they write to the memory card is a quality-reduced JPEG! And what X-camera user likes to skimp on quality?

Wait, there’s more! The camera’s IMAGE SIZE settings (3:2, 16:9 or 1:1 format with resolutions L, M and S) aren’t available in “RAW only” mode. They are greyed-out. This feature can be valuable for RAW shooters, though, because the camera’s light metering is influenced by the current format settings. If you intend to shoot (and later crop) images to a ratio of 16:9 or 1:1, the light metering works more effectively when the camera’s image format is set accordingly. That’s because parts of the image that are superfluous will be automatically cropped out and won’t affect the camera’s exposure metering (which is based on the current live-view image). Furthermore, it’s easier to target your desired image area when the image format in the camera’s viewfinder matches up with your intended end result. Finally, the camera adjusts the size and shape of the autofocus fields and redistributes them according to your selected image format. This means that you can continue to use all 49 of the camera’s AF fields even when you are shooting in the exotic 1:1 format.

No worries: Independent from any IMAGE SIZE or IMAGE QUALITY settings you choose in the shooting menu, your X-Pro1 or X-E1 will always record a full-size L, 3:2 format RAW file. You will not lose a single pixel.

Why “JPEG only” shooters should use FINE+RAW

Now that the “RAW only” camp has been served, what about the “JPEG only” crowd? After all, this is what this article is supposed to mostly be about, right?

The reason to opt for FINE+RAW comes down to this: All X-series cameras feature an internal RAW converter (PLAYBACK MENU > RAW CONVERSION) that allows you to change an image’s JPEG settings anytime after you take a shot. However, before we examine the implications of this feature, let’s find out about those mysterious “JPEG settings” and let’s see what they actually are.

JPEG settings (or JPEG parameters) are camera settings that do not affect the RAW file. Instead, they only affect the look of any JPEG files your camera spits out. Thinking of RAWs as “digital negatives” and JPEGs as “digital lab prints”, the camera’s JPEG settings determine how the JPEGs actually look like.

JPEG settings are:

• White Balance
• WB Shift
• Film Simulation
• Color
• Sharpness
• Highlight Tone
• Shadow Tone
• Noise Reduction (NR)
• Color Space

As you have probably noticed, there settings are scattered over the shooting and setup menus of the camera. With the exception of color space, they are also directly accessible via the Quick Menu and can be saved in sets known as custom shooting profiles. The same JPEG settings are available when you activate the camera’s internal RAW converter.

JPEG settings strongly affect the look of an image. The very same shot can look quite differently depending on what JPEG settings you have chosen. Here’s an example of a snapshot I took recently—the following pics all show the same RAW image (“digital negative”) processed with different camera JPEG settings to produce different “digital prints”.

Let’s start with three different color versions:

And here three different black&white versions, again all courtesy of the X camera’s flexible JPEG parameter settings:

As you can see, there can be both strong and subtle differences between different “digital prints”. There are virtually billions of possibilities of how you can combine these JPEG settings to generate an actual image. Quite overwhelming! With normal cameras and as a “JPEG only” shooter, you would have to know/guess and then set the “perfect” JPEG parameter combination for each image in advance. Can you actually do this? Honestly, I can’t.
