How to Use the Fujifilm RFC RAW Convertor: Part One

Scroll down to content

A bit of a departure from talking about the X-Pro series for this instalment!

I thought it was time to have a closer look at the RFC (RAW File Convertor) software that’s supplied by Fujifilm with their cameras (and also available for download from their website)

This software is pretty much universally hated!!

Clunky, slow and illogical – it’s easy to see why no seems too like it.

So am I about to educate you that it’s not clunky, slow and illogical?

No, that’s not possible!

But that said, not using any other process/RAM heavy application while you’re using RFC can make a difference in its operating speed.

However RFC is not without usefulness and in my opinion; anyone not needing or wishing to buy, a full-on RAW convertor or anyone who just needs a separate app to generate .TIFF files for use in a more fully featured product, could do worse than use this completely free of charge, (supplied by the people who make your camera) piece of software

RFC is supplied by Fujifilm, but is made by Ichikawa Soft Laboratory Co.Ltd, a Japanese company. The version supplied with Fujifilm cameras is a stripped down version of their more fully featured SikyPix Developer Pro software.

So in the coming parts we’re going to be taking a look at it’s features, what it can do (and what it can’t) and how to use it.

Before we start editing any images, let’s take a look at the features and options and how we might want to set them up.

This is the full screen of the application, which should be the view that greets you when you launch the app

To begin with, you should head to the Options Menu in order to make some changes

Setting For Developed Image

Here I personally recommend having RFC add a suffix to your developed images. Applying a setting here will add the suffix to all images that RFC develops. I’ve chosen ‘RFC’ so that I know my images were made in this application. In this example, the setting will have the effect of naming your files _______.RFC.jpg. This can be handy if you have SOOC Jpegs and RAFs in the same folder, it will stop RFC wanting to overwrite your SOOC Jpegs, with its developed Jpegs. (For example, if set to shoot RAW + Jpeg, your Fuji will give you 2 Files; DSCF1234.RAF & DSCF1234.jpg. On standard settings, RFC will want to output the file its created from DSCF1234.RAF as ‘DSCF1234.jpg’ but that file already exists)

I would also set the output quality to the highest setting

The next item from the options menu is Display Settings

Here you can specify any colour profile management that your monitor may have and what side of the screen the tools to reside.

For Preview Display System, the default setting is a ‘coarse’ preview (full image view, which is very slow to update) and a more accurate ‘zoom to 100%’ view for when you need to check a specific part of the image

If you have a colour profile for your screen, set it from the Display Settings Monitor Profile drop down menu

The next item is Function Settings dialogue box

Function Settings

The next item from the Options Menu, is the Function Settings. Here you can specify at what point the auto exposure tool meters for; as well as the level at which the shadow and highlight “blinky” warnings kick in at.

Two important changes I recommend here

1)Enable continuous operation of the Eyedropper tool

2)Cache settings – MAXIMUM

The first setting means that when using (say) the WB selector tool, if you want to click more than once and try a second (or 3rd, 4th etc) WB from a point in the image, then you don’t have to re-select the tool each time. (But you will have to manually deselect the tool after you’re finished with it)

The second settings gives RFC it’s max performance on your system… It’s still slow though  🙂

If you want RFC to ONLY work with RAW images, tick the box at the bottom left “Operate RAW Data Files Only”

The next item is Key Customisation

If you love keyboard shorts – here’s the menu to make them/change them and a list of the shortcuts native within the app

The next item is Default Parameter Settings

This menu determines the “pre-set” that RFC applies on image opening.

Selecting a new Default Parameter Setting

Later I’ll show you how to make pre-sets, but once you have a pre-set you want as a starting point for all of your RAFs, you can select it from the drop down and it’ll be applied on initial image opening

The Options Menu has a additional options sub-set

The Delete Access History clears the cache of where you’ve opened files from on your computer

If you’ve changed the position of any of the tools, the Initialize Location of Controls resets them to default

Change the ‘Skin’ Colour of the application

The Help Menu:

Initialize User Configuration File = deletes all your custom settings

Delete Temporary Files, clears the cache on your computer from the files left by image editing

The Trouble Shooting Menu.

The items here are explained accurately.

Next time we’ll take a look at the native tools within the RFC application.

It’s not as under featured as some would have you believe…

  1. Thank you for writing this. I’ve been planning to pick up Iridient Developer, but I might spend some time with this app too thanks to your efforts to explain. Have you any experience with the full SilkyPix app? I suspect it’s similar in some respects—not immediately logical compared with other RAW processors, but quite comprehensive in functionality and capable of high-quality results.


    1. Hi, thanks very much. This was quite painful to write and took a lot longer than I expected! I’m not sure many read it when I first wrote it a few months back, but lately its been getting attention! Must be linked somewhere… DPR I think..

      I’ve never used ID, so I can’t compare – but I own and regularly use the full SilkyPix app. It’s not *that* much different to the RFC one, but does feature highlight and shadow recovery, and many of the other tools have a couple more features.

      IMO SilkyPix rewards well s/he who exposes well in camera, and isn’t processing gigs worth of data. For selective editing (eg masking) it’s very rudimentary and many other apps have a lot more to offer in this department

      I do like it though, I think it makes an organic looking image and I like the colours.

      Start trying too ‘ISOless’ push images by 3 stops though and things quickly get gnarly!

      Liked by 1 person

  2. Hi Adam – Does RFC allow one to see the color RAW image without the jpeg simulation ? for example I shoot JPEG+RAW in BW mode. The RAW files also show up as BW in RFC. Anyway to change that ?


    1. Hi Roshan,

      You can pick any of the Fuji film simulations (and some RFC ones) from the colour menu drop down.

      You can also pick a film simulation and make it a preset so that RFC always selects it


  3. Thanks for this Adam – I’ve struggled to get into RFC but this has been a big help. I’ve tried a number of RAW file converters since switching to Fuji several months ago, but have been most consistently satisfied with the results from RFC. Once you get used to the interface it has a certain antique charm 🙂
