In the 3rd part of my test I would like to show you a D5300 real photo quality and utilizing High Dynamic Range in the pictures.
The most decisive thing about buying a right camera is its photo quality. There are many cameras which offer plenty of modes, options and amenities but when they don’t make good photos then everything is bad. Basically you can find some information about the photo quality from the producer’s website or forums. Main parameters, which may indicate which camera is able to make a good photos are a sensor size and a resolution. However you should have it in mind, that a big resolution isn’t enough to make a good photos. The size of sensor is the most important thing in every camera, even in phones. This part of equipment decides about your photo quality. You may have a smaller resolution and make much better pictures. Checking the parameters is not only a way to find out about the picture quality of camera which you are going to buy. When you are going to buy a new equipment you should browse deeply the internet and try to find sample photos from model, which you are interested in. When you find the pictures from the camera model , which you would like to buy you will make your own conclusion about that. Every photographer has a different point of view. Basically you are picking up the thing, which will make you happy not disappointed!
I prepared a couple of pictures, which I would like to share with you and indicate some details. Every picture has been done in a full resolution 6000×4000 pixels. The smaller resolution wasn’t taken into account. As I wrote in previous articles Nikon D5300 gives you a choice to change the photo quality in 3 steps: Fine, Basic and Normal (Pic.17). I would like to show you below what is the difference between the best and the worst quality of the D5300 photo.
Pictures 1 and 5 show the landscape made in the best quality. The picture 1 was made using manual focus and the picture 5 using autofocus. The pictures 2 – 4 are detailed parts of the picture 1, same like pictures 6-8. There is a lot of stuff in Web about autofocus mode in Nikon D5300, so I am not going to develop this topic here. However everybody can see the difference between both of this pictures when see the detailed parts below. It s hard to adjust focus manually when you are looking throughout the viewer. You can use a live view mode and make a little bit zoom in to see details of your view, but the live view option influences on your battery endurance.
Picture 9 has been done in the lowest quality. I cut the image up to 2/3 and delimited details on treetop, where you can see many branches and twigs (Pic.10). As you can see a dark arrow shows the branch (dark) and some yellow line, which is parallel to the branch. Those of lines are everywhere. In my opinion this is kind of chromatic aberration, which may be also called as a chromatic distortion. The branch may be here as a our dark highlight with the blue sky beyond. Those of coloured fringing around the branches and twigs may be due to the receptors for different colors having different sensitivity, therefore preserving detail in one or two colour channels . This is noticeable especially in the lowest quality pictures. When you make a photo with better quality this effect is going to be reduced.
A picture 11 has been made in medium details and shows a hair from 30cm distance.
High Dynamic Range (HDR)
High dynamic range is a technique used in imaging and photography to reproduce a greater dynamic range of luminosity. The aim is to present a similar range of luminance to that experienced through the human visual system. The human eye adjust constantly for the broad range of luminance present in the environment. The brain continuously interprets this information so that a viewer can see in a wide range of light conditions.
You must know, that basically every picture contains two areas of different sensitivity. The first area is our object, which we are capturing like a building, landscape, etc. The second area is the sky, which may contains a sun, clouds or some remote barely visible objects like mountains, etc. In typical, compact camera like Canon SX130 IS (my previous model) you can enjoy the object, unfortunately with a white sky, especially during the day, when the sky is covered by high-level or mid-level clouds (Pic.12 -15). In another case you will have beautiful sky, but your object will have shown like a dark contour without many details. A basic role of HDR is to put those of areas together and make your photo readable and tidy.
The D5300 offers a feature, that provides automated HDR photography. When you enable this option, the camera records two images, each at different exposure settings and then produce a single HDR image. When you enable the HDR option you have the choice of the following (Pic.16,17). If you select the automatic mode, the camera will choose what it considers the best adjustment. I didn’t use this option during my test. I focused on experimenting with HDR to find out the behaviour of this feature in different conditions.
As you can notice below I used HDR during a few situations:
– a late dusk in the town (strong light pollution) (Pic.18-21)
– a front of the direct sunlight (Pic.22,23)
– an opposite to the direct sunlight, a typical daily picture (Pic.24)
– a big sensitive difference with fair sky and dark surface (Pic.25)
In the captions you can find information about photo details. Each image contains a photography from the same place multiplied by every D5300 HDR option. Red text shows the optional and the most realistic effect created by HDR tool.
Another examples, especially those with its extreme limits show something of a graphic-novel look. When you decide to use HDR feature manually you will need to adjust it correctly. Otherwise your effect won’t be noticeable or you will create something which has the look of a hand-tinted photo. When you exaggerate and put too high HDR value you will see some awful dark “border” between areas of different luminance. The yellow arrow shows this area on each picture. When you see this on your photo, it means, that your HDR value at this moment (day, sunlight, townscape, twilight, etc.) is too strong.
In general the HDR option during the twilight is useful when you don’t have a tripod and you need to make a photo with short exposure without a big ISO sensitivity.
Sometimes the sunlight is too strong and we can’t make a good picture anyway (Pic.23) then you need to find a place outside direct sunlight. As you can see on the picture below even with extra high HDR level the radiator below the window is barely visible.
Some images from picture 25 shows best example to make HDR photos quickly, but unfortunately not properly. HDR tool needs to make 2 photos, so you need be patient and try to keep your camera still. Otherwise you may receive noisy effect.
You can use HDR in RAW images too, but you can’t enable this option manually. The camera manages this tool automatically. When you will take new photo you will see the results. The same as in D5300 modes, there in general HDR is not available, but you receiving quite real photos. See another HDR photo examples below:
