A few days ago, I exposed this high contrast view of Conway Scenic Railroad’s Budd RDC ‘Millie’ at Conway, New Hampshire using my Lumix LX7 digital camera.
The camera simultaneously saves each exposure as a RAW and JPG file. I’ve set the camera to profile the JPG with the in-camera ‘Vivid’ color setting.
In this sequence, I compare the un-altered camera RAW (RW2) file with the un-altered in-camera JPG file and my altered (adjusted) Jpg image that I manipulated in Adobe Lightroom to make the most of the camera RAW data. Notice the differences to shadow and highlight detail.
I’ve also included a screen shot of the Lightroom work window to reveal the changes that I made.
Autumn sunrise. No two are the same. The mix of clouds and particulates in the air make for endless mixtures of texture and color.
Last week I arrived in Worcester to take the 7am MBTA train to Boston.
I made these sunrise views using my FujiFilm X-T1 with 12mm Zeiss Touit lens handheld.
Working with the RAW files, I made some minor adjustments in Lightroom to balance highlights with shadows and tweak color balance.
The RAW file is not what your eye sees.
Where the in-camera Jpg uses a pre-profiled set of parameters in regards to color saturation, contrast etc. The digital RAW file represents the data as captured by the camera and is comparable to a film negative; it represents an intermediate step that requires adjustment and interpretation to produce a pleasing photograph.
I typically expose both a pre-set in-camera Jpg (often with one of Fuji’s digitally replicated film color profiles, such as Velvia) and a RAW file simultaneously.
Thursday morning on my way to breakfast, I made this photo of Irish Rail’s IWT Liner (Dublin to Ballina) passing Islandbridge Junction.
I timed my visit well and so only waited a few minutes for the freight to pass.
I’ve often photographed the IWT at this location, so this was really just an exercise.
Soft morning clouds made for some pleasant lighting, but also a post-processing quandary.
My FujiFilm XT1 allows me to simultaneously expose a Camera RAW file and a camera interpreted JPG. Among the features of the Fuji cameras is the ability to select a film-like colour profile for the Jpg.
In this instance I’ve opted for the Velvia profile, which closely emulates the colour and contrast of this popular slide film.
Another colour adjustment is the white balance control. In this situation I selected ‘auto white balance’, which means the camera interprets the color temperature.
When I processed the photos, I wanted to see if I could improve upon the camera JPG by making subtle changes to the Camera RAW file (which has ten times more information imbedded in it than the Jpg, but serves in the same role as a ‘negative’ and is intended for adjustment rather than uninterpreted presentation).
Below are three images; the a JPG from the unmodified Camera RAW, Camera created JPG, and my interpretation of the Camera RAW file.
Incidentally, by using Lightroom, I can make adjustments to the RAW files without permanently changing the original data. This is very important since it would be a mistake to modify the original file. That would be like adding colour dyes or bleach to your original slide to ‘improve’ the result.
