This is the first camera, which gives me possibility to run RAW process. Nikon has his own filename extension for RAW files – NEF images.
A camera RAW image file contains minimally processed data from the image sensor of the digital camera. RAW files are named so because they are not processed yet.
RAW files contain the full resoultion (typically 12- or 14-bit) up to 16-bit, when the best JPEG files contains only 8-bit resolution. When you shoot in a format like JPEG image information is compressed and lost. Once you use the RAW format, no information is compressed, thereby you are able to produce higher quality images.
When you shoot the RAW, you are able to make a photo processing and make decisions on how the image should look like. This topic isn’t brand new and ground breaking. It has been described in the web a couple years before.
I am aimed at show you the RAW processing features provided by Nikon D5300 Digital Lens Sensor Camera. Prior to this article I wrote about processing JPEG images in the D5300 model.
To start RAW image processing you must choose NEF (RAW) processing from RETOUCH MENU (Pic.1) and next pick up the photo from your current SD card folder (Pic.1).
You can adjust the settings listed (and described) below:
a) Image quality – fine, normal or basic. Record JPEG fine images is at a compression ratio of roughly 1:4, accordingly 1:8 for normal and 1:16 for the basic quality.
b) Image size – You can save your output photo in 3 basic image sizes (Pic.2).
.c) White balance – ensures, that colours are unaffected by the colour of the light source. You have the choice of the following (Pic.3):
Picture 4 shows the example choice – Fluorescent. Once you decided to use the fluorescent light balance you will have another choice of the following: (Pic.5)
The colour temperature (Pic.6) is very important in adjusting your photos. It is an objective measure of the colour of a light source, defined with reference to the temperature to which an object would have to be heated to radiate light in the same wavelenghts. Light sources with a higher colour temperature appear like more blue.
After the choice of the colour temperature you may modify the colour balance also, as in the JPEG imge (Pic.7).
See for the examples below: (Pic.8 – 12).
d) Exposure Compensation – is used for make the pictures brighter or darker (Pic.13 -16).
As you notice, that some pictures are more green. You can adjust your photo by more features in the same time!
e) Picture control – in D5300 is quite big. You have a dozen or so options to processing your RAW image (Pic.17,18).
When you selected a proper picture control you can adjust settings (Pic.18). To make a quick amendment you can select QUICK ADJUST to choose a preset combination of settings. When you need more accurate adjust then highlight the desired setting and choose a proper value (Pic.19).
For every picture control the adjust interface is the same except Monochrome, where you can adjust filter effects and tone (Pic.20,21) instead saturation and hue. Remember that you can use the filter effects to enhance contrast, to tone down the brightness of the sky in landscape photographs (Yellow, Orange, Red) or to soft skin tones (Green).
See the examples below (Pic. 22-31):
f) ISO Sensivity – is a measure of the camera’s ability to capture the light. In D5300 you have the choice between ISO 100 and ISO 12800 with extension to 25600. Every RAW image may be modified within 4 levels of ISO sensivity: AUTO (OFF), LOW, NORMAL and HIGH.
g) Color Space – determines the gamet of colours available for color reproduction. You may choose sRGB which is recommended for movies, general-purpose printing and display and Adobe RGB, with its broader gamut of colours, which may be using for professional publication and commercial printing (Pic.32,33).
h) D-lightning – same as in Jpg images.
Finally you can make endless amount of Jpg photos from the RAW image. The animation below shows every image processes together (Pic.34).
This is just part of exercise, which you can make with D5300 model. You can also use proper software to RAW processing on your computer. See the list of programs below:
– RAW Therapee 4.2
– Capture NX-D
– Photoscape 3.6.3
