During the winter, the colours turn more monochrome and many pictures also turn slight blue due to the snow reflecting the sky. Many cameras reads this wrong and end up setting the colours profile to cold.
One way to avoid this is to adjust the profile in your camera manually. An other way is to set the camera in black and white settings. If you have a mirrorless your electronic viewfinder will be black and white as well.
I’ve taken this to a new level by converting one of my cameras to infrared. I’ll give some more details of the actual work involved in a later post. Infrared is a light that the human eye don’t see. The image sensor of a camera is normally filtered to not see this light, but with a little surgery the camera can convert this light to something visible to the human eye. The result is a deep black and white image with a lot of contrasts and some unexpected contrasts.
One morning I was out with my dog and fortunately I brought my camera. As the moon was dipping the horizon and the sun was on its way up, the mist also arose from the close by river. All together it was a magical morning.
The morning can be quite challenging to capture. Especially when parts of the scene is lit. My camera got a in body stabilisation and paired with the right lens with stabilisation it really helps on low light scenes like these. If you don’t have a camera with these features you could use a tripod. These images are captured at 1/40s, f/8 and ISO400.
The weather has been nice for a long time now. Crystal clear nights and some clouds in the horizon during the day. But since the days here up north are pretty short (only 6 hours at the time of writing this post) the temperatures will be creeping downwards. Right now it has stabilised at approximately -18C.
I went out to the local river and the breeze that comes together with the water flowing is extreme. The last rays of sun had just faded and the blue hour started. Mist arose from the river and created a magical, but cold, moment.
During these hours you might be able to catch something special.
It’s been a while now, but I thought you might wanted to see a bit of my latest project. When I swapped out my Canon gear for the new Fuji, one of the lenses I was most exited to get my hands on was the 100-400, witch on a Fuji X-mount equals about 150-600mm.
My first experiment was small birds on a bird feeder. I made one from old branches that were cut of a fallen tree. I wanted to have a natural background so I installed the feeder in my back yard.
Sitting on a little chair in the back yard waiting is a game in it self. It really takes patience, but the birds eventually showed up.
After almost a decade with a full format camera, I am considering swapping back to a crop sensor. Why? You might ask. To explain this I have to start early in my digital camera career. I started out with a compact Canon G6. 1/1.8” sensor and quite good quality. Soon I realised that photography was what wanted again after years away from a camera. So I ended up buying my first DSLR, a Canon 350D with a Sigma 24-70mm Lens. This was a great camera. One day I came across the Canon 7D I knew I had to have it. The lust for quality images grew. The quality was, in my opinion, strongly related to sensor size and the purchase of a Canon 5D Mark III was a fact.
In 2016 I realised that my expedition across the Greenlandic Icecap was going to be without my dear Canon 5D Mark III. The reason was that I had to drag along at least the 24-70mm f/2.8, a spare battery and a charging system for those 7,4V batteries. My solar charging system was only at 5V. This meant that I had to bring some bigger and heavier gear to accommodate my full frame. Ending at over 3 kilos of equipment. The result was a Sony RX100MK2. And luckily the images looks great.
A while after the expedition I got hold of a Canon M100. A nice little camera with a 15-45 lens and a 22mm lens. Both are quite acceptable but not close to the quality of the 5D. I bring along the smaller M100 on my mountain bike trips. If the trips are long I almost always regret not bringing better gear. I did how ever ditch the 5D because of its weight while packing for the trip. If the trips are short I go back later with my big camera to get those images. The M100 is a good camera, but the selection of lenses Canon got for the EF-m mount is not. There is barely a handful of choices and they are all entry level ones. Of course I could have had the adapter and bring my full size lenses, but then again the compact format of the M100 is a bit wasted.
And then a good offer from Fuji got me thinking. I’ve selected so big and heavy gear that I have upgraded myself away from mobility. The alternative I got isn’t a real alternative because I know what I could have had. And here is where the Fuji X-T4 comes into play. With professional quality glass in the 16-80mm f/4 R OIS WR it is weighing in at total of about 1 kg. About 350g more than the M100 with the kit lens and almost a kilo less that my Canon 5D with a 24-70 f/2.8. The size is acceptable as well. I could have done a lot with the 5D to get it lighter, but the fact is that the body alone is close to a kilo.
The question now all comes down to the quality of the image. And quality does not necessarily come from the amount of mega pixels on the cameras sensor. My Canon 5D Mark III got 22.3 megapixels, my 5Ds got 50.6 megapixels and my M100 24.2 megapixels. Even if the pixel count on the M100 is higher that the 5D Mark III, the 5D produces better results. To understand this one have to analyse everything from quality of the glass to the sensor technology.
The difference between the tiny mirrorless Canon M100 and the Fuji X-T4 is that Fujifilm wants the X-4T to be used by professionals and are following the camera lineup with a lineup of high quality lenses.
After almost a month of testing I’ve come to a conclusion. It is actually the X-T4 that will get to tag along on the next trips.
Have you been thinking of becoming a photographer? After years with a camera (or more) I’ll try to share my perspective and give you some advice on how to begin.
The no cost start
I have two, potentially, expensive hobbies. One is biking the other is photography. I call them both hobbies because I don’t earn enough to be a professional in neither. The one thing that annoys me the most is the fact that people for some reason needs to spend a months income just to try out a new hobby. I believe that the more you spend on figuring out if a hobby is worth doing, the harder it is to admit that it’s not. You kind of force yourself to like biking if you spend €5,000 on a bike. And the same goes with the camera.
This is why I’d recommend a no cost start. The only thing you’ll need is a camera of some sort and most smart phones today have an acceptable camera. An other option is to borrow a camera from a friend. At no cost, there is nothing at stake. Go for a walk. See if you can find anything you like to photograph. Maybe join a friend who already do photography for some tips and inspiration.
And don’t think that that one trip to the local woods is enough to determine if you will go on with your photographic carrier. Give it a month or two.
Kicking it up a notch
So you’re still out taking pictures and have figured out that you’ll upgrade from your phone to something that will give you better results? Still I’d recommend you to keep the cost low. The lower the stakes the better are the results. If you start searching for information you will find a load of forums recommending different camera equipment that you MUST have but the fact is that you really don’t need anything for a good start (remember your phone). All modern cameras today will yield acceptable results. It’s mostly about personal preference.
If you have the possibility to visit a local store hold the cameras you should do so. How the camera feels in your hand is totally different from a reviewer’s opinion on a Youtube video. Dials and knobs have to be placed so that you feel that you can reach them. And since a modern camera is more or less like a computer, you need to be comfortable with all those menus and how they work.
When you have decided on brand based on these tests I’d recommend you to buy a entry level kit with interchangeable lens. Today one normally talk about Digital Single Lens Reflex (DSLR) or Mirrorless camera. There is pros and cons for both systems. As a starter you will be fine with both. Again it is a personal preference, but it seems like most camera brands have their focus on the Mirrorless cameras these days.
If you haven’t already you will find out that there is something called crop factor. And there is a load of discussions on forums on the topic. Basically the old 35mm film has the definition of a full frame sensor in the digital world. Meaning that a full frame sensor is 36x24mm. If a sensor smaller then it has a crop factor higher that 1. So a APS-C that is 23.6×15.7mm will be 1.525 times smaller than a full frame and therefore has the definition of beeing a 1.53 crop factor.
You will find professionals using both full frame and crop factor cameras. Crop factor cameras are often smaller and lighter. Same goes with lenses. Crop factor gear is often priced lower as well.
So my general recommendation is to get a entry level mirrorless kit. In this segment there is a handful alternatives.
Have you seen those beautiful signatures some put on their photos and maybe tried yourself and failed? In this article I’d like to give you a recipe. As long as you have a computer and a camera, you will manage this.
Of course you could choose to use a computer with a touch screen and a pen and make yourself a signature, but not everybody have a touch interface. So the first thing you do is to find a pen and a paper. If you have a black pen, that’s the best.
Make a hand written signature on your paper as you would on any formal letter. Once you’re satisfied with the results you use your camera to take a photo of your signature. Try to get as good light on it as possible.
There is a handfull of vector services online, but the one that I have had the most luck with is Vectorizer (This article is not sponsored or endorsed by Vectorizer).
You simply load your image up to their online vector editing tool and start tweaking. First you crop your image, then you set the model to “Drawing (Black and white)” , then you adjust the threshold so that the output image will have the signature in one colour and the background in the other. On the left side you see two Color wheels. Click the middle one that represents the collection of light colours and replace it with a completely white one and the same with the dark one to a completely black one.
Then you hit “Vectorize” and then “Download”. The result is a vector file of your signature. So why do you want a vector file you might ask? Well, a vector file is a bunch of coordinates. Coordinates scaled up and down will still be coordinates. Rendered into a raster graphic after rescaling will lead to a much better result than just scaling a raster in the first place. The next thing is that it is a really simple way to get a clean file/signature.
I prefer Photoshop, so where is where you can add this file to Photoshop and get a nice looking signature. You can add this file as a layer in most photo editing softwares supporting layers and vector graphics.
Back in the film days a common way to modify the final result was to add filters in front of the lens while capturing those photos. These filters can be used on a digital camera as well, but the results might be a bit different.
A lot of these filters manipulate colors. Filters like yellow filters, grey filters, red filters, warmth filters and so on, will generally be of little use as long as you know how to use a photo editing application. Combine this application with a RAW format file from your camera and you are good to go. The raw format save all your sensor information and makes it easy to adjust color warmth (Kelvin) in your image and the balance between Red, Green and Blue.
There are a couple of filters that are hard to mimic in an application. Filters that reduces light and polarizing filters. The first group is actually filter that you don’t really need unless you want a 60 second exposure at a sunny day. Neutral Density (ND) filters will just reduce the amount of light that lets trough to your sensor. You can do this partly on your camera, but a 60 second exposure is hard to compensate with high aperture value and low ISO numbers. And a photo taken with f/5.6 and 1 second exposure at ISO100 will be totally different that a photo taken with f/22 and 1/100 second exposure at ISO100. To understand the relation between aperture, time and ISO, have a look at this post.
While ND filters reduces all light other filters can reduce light at a given wave length. Night sky filters are filters that stops wave lengths from mercury vapor and sodium. This will reduce light pollution from close by cities. The most commonly used filter is the Ultra Violet (UV) filter. Film cameras had to have this filter to stop UV light from hitting the film. Today a digital camera got this filter built in, with some exceptions.
Polarizing filters will only let through light waves/rays that has a given orientation. Once you turn the filter, waves from reflections on your objects will not let through. If you use a polarizing filter on a camera pointing to a puddle or a calm lake you can decide if you want the reflection or the bottom of the puddle or lake. If the water is too deep you will only see a non-reflective surface in a dark colour. This filter can be used on most surfaces that creates reflections.
I mentioned ND filters but there is a group of ND filters that you really don’t need and that is the graduated ones. As long as you know how to use your photo editing application, applying a exposure compensation on parts of the images is really easy. If there is a big difference in exposure levels on your subjects you might need to bracket the image on two or three exposure adjustments. Adding a filter on your lens will result in a permanent adjustment on your raw file. If you put the filter on just a centigrade out of line, your image is ruined permanently.
So what you really need in your photo bag is a polarizing filter and maybe a ND filter or two if you like to take long exposures. If you’re into night photo and want to get rid of that light pollution you can buy yourself a filter that removes these wave lengths.
Hope this article was of interest for you and that it made sense. Do not hesitate asking questions or post comments.
Norway is still affected by Corvid-19 and it is strongly advisable to stay at home or close to your home. Since we live on the countryside its possible to move around a bit, but not too far. My family live in a valley called Orkdal and the hills surrounding this valley is mostly covered in forest and farmland. One evening I was out biking and I came across this beautiful little area with some old trees and rocks. I always bring a camera with me, but my M100 was not capable of capturing all details in those trees.
A couple of days later I went up there again with my big camera (Canon 5Ds) and my 24-70mm lens. I’m really pleased with the result.
In the early days I read all the technical stuff I could find about photography, but it didn’t really make me a better photographer. So my general advice is to go out there and try and fail. One day you will succeed.
I still do recommend that you go home and analyze your efforts and try to understand why your results aren’t as you expected. Understanding how composition work is not an easily learned subject, but understanding the technical result of your photo can be thought because it’s a technical answer.
So let me try to explain this in a simple manner. All cameras behave the same. Some might not have the possibility to adjust all parameters, but they do the same behind the scenes. To capture an image the camera will evaluate something called Exposure Value or EV for short. This is the amount of light reflected/emitted from the objects you want to make an image of. Now the camera does an equation of three (3) parameters. The time (T) one should spend taking the image, the amount of light (A) one should let trough during that time and the sensitivity (ISO) of the sensor.
The relationship between the four (EV, T, A and ISO) can be written as a formula. You don’t walk around thinking of formulas when you capture a beautiful scenery, or at least I don’t. So let me present a figure for you instead.
By this simplified figure one can state that, given a defined EV, one need to adjust either Aperture (amount of light that is presented to the image sensor) or Time if one wants to do an adjustment of the ISO (Sensitivity of the image sensor).
In full auto mode the camera will make an effort to adjust these parameters based on given rules. If you choose manual mode you will need to handle all these parameters yourself. So why do you really want to do this if the camera can do it? Let me explain that for you as well.
If you look into the front glass of your camera you might see several blades going into each other. In the middle you will see a hole. The diameter of this hole is adjusted up and down according to the selected aperture number. This value is often presented as a f-number. F-number is a relation between focal length and aperture. Let’s just use this f-number for now since that is what the camera will show you. As the f-number grows the aperture diameter get smaller, resulting in less light getting to your sensor. So as the f-number grows the scenery goes darker.
But there is second effect of the aperture. As the f-number grows the depth of field also grows. Now what is depth of field (DOF) you might ask yourself. If you want a portrait with a nice blury background you want a shallow depth of field. If you have a fantastic landscape with a foreground tree and a beautiful mountain behind it, you will want both to be pin sharp. Then you want a deep depth of field (big f-number).
Now time is a safe one right? Not necessarily I’d say. Time is often measured in seconds on a camera. Some talk about minutes, but this is for special occasions. So lets keep to seconds for now. The more time you spend exposing your image the more light will be presented to your sensor. What you seldom think of is how far an object will move during a second. And also how much your hands will move (shake) during a second.
With some practice you will be able to handheld your camera at about 1/[focal length] second rounded down. Say you have a 50mm on a full format camera, you will be able to handheld 1/50s which will be rounded down to 1/60s. If you concentrate you might be able to get good images at 1/30s.
Now over to your image. How far will your object move during 1/60s. A car moving at 90km/t translates to 25m/s. During that 1/60s the car has moved 42cm. This will lead to a nice and crisp image except for the car witch has motion blur. Of course this can be done by intention, but you should know the effect of a slow shutter speed (time).
The final parameter is the ISO or sensor sensitivity. Basically the higher the number the more sensitive will the sensor be. The negative side is that the more sensitive the sensor is, the harder it will be to be accurate. This introduces noise in your final image.
This can easily be illustrated with two buckets and a glass. If you fill one bucket with water and pour that water over to the other bucket it’s quite easy to stop at a certain height in that big bucket. If you take the same bucket at try to stop at a certain height in a glass, you will most certainly go over or under the line. The big bucket is a sensor at low sensitivity (small ISO number) and the glass is a sensor at high sensitivity (big ISO number). The deviation between the height in the glass and in the bucket will be visualized as noise.
So let’s try this in normal day light. The Exposure Value is at a level that can leave the ISO to a standard 100 or maybe even a extended low value at 50. The Aperture (f-number) can be placed at maybe f/8 and the time at 1/200s. This means that any camera can operate at it’s best. Even the mobile phone camera gives acceptable results. A camera set to automatic mode will give you good quality images in most cases.
Now let’s imagine another situation. You’re out during the twilight to capture some wild animals. The light conditions are totally different. The Exposure Value will be quite low. You have your long focal length lens with you to capture those shy animals. It might be a 300mm or 400mm lens. Handheld you will need about 1/300s, so maybe you are lucky if you get a good shot at 1/200s. The lens has a f/5.6 at minimum meaning that you have to sacrifice something. Either time has to go up or ISO has to go up. You either introduce motion blur (you are moving the camera while capturing the image or the animal will move) or you add noise.
Most cameras will struggle with this in automatic mode. This is actually outside the comfort zone of the camera. The camera is programmet to reduce speed and f-number down to a certain level and then start rising the ISO number. With manual mode you’re able to do some tweaking of these parameters and the amount of acceptable images might go up. Here is where you should be in control of all those parameters yourself.
A final note to camera gear is that an expensive camera body will add less noise on higher ISO-numbers. An expensive lens will have smaller f-numbers that allows more light to get to your image sensor. This does not mean that you need to spend a fortune on new gear, but now that you know your gear limitations you can go out there and push it to its limits and see what you have to deal with.
