== Photo sessions == | |||
It may seem all too obvious how you should take a photo, however, to the best of my judgement, I made a list of quick suggestions to apply while the remainder of the page shows the reasoning behind them in particular details. This should ensure you take at least above average shots, when given the opportunity. Always keep in mind that a session could get longer or shorter, depending on context, and you need to agree in advance with your subject, if this applies. Never rush a session or have one when exhausted, the risk of ruining such an opportunity is too high. | |||
Avoid considering a good photo as being the result of simply pointing the camera and creating a lasting memory. Great shots require at least a degree of planning that takes 5-10 seconds in the least. Always consider how much the subject is able to cope with such requirements and avoid needlessly exhausting him or her when you are just testing various approaches. Require undivided attention only after the final preparation stage. Avoid too much experimentation with poses and shooting techniques unless there is a broad agreement with the subject, a shooting session is exhausting and your subject may have to experience more on the same day. Acting kindly and understanding matters a lot. | |||
=== Advanced preparations === | |||
Ensure you have the right setup on your first photo. It is easy to forget what you used last time, so you need to get your camera back to the typical settings. That means no optical zoom or having the default camera focus length, the default 4:3 or 3:2 image ratio, a clean lens (particularly for smartphones), the photo mode you always use preset, no pre-applied effects, and a well-charged battery. | |||
When you need or want to experience with modern accessories such as straps, lights, stands, always do so well in advance of your shooting session. Having prior knowledge on how they behave, no matter how subtly the change feels, will matter a lot in the stress of a photo session, where everything has to be well rehearsed and executed precisely. | |||
=== The shooting rundown === | |||
Advanced preparations: | |||
* Decide whether you want a wide or a narrow angle shot, a portrait or a landscape one before doing anything else; | |||
* Decide where outdoor light offers the best conditions or adjust indoor light to your needs, if possible; | |||
* Avoid taking photos with the light behind the subject, or when large shadow areas occur, in front of the camera; | |||
* Avoid direct sunlight falling unevenly on the subject, unless you really want an artistic effect; | |||
Final preparations: | |||
* Attempt a quick initial framing to give a good idea on the optimal distance to the subject, do not take a picture yet; | |||
* Observe and avoid other subjects or elements that are drawing needless attention to them instead of your subject; | |||
* Adjust focal length on your camera or switch to a different optical magnification factor to reach optimum framing; | |||
* Try focusing and exposure adjustment on different parts of the picture to reach even subject exposure (smartphones); | |||
or | |||
* Try focusing on different parts of the picture to reach even subject exposure (semi-professional/professional cameras); | |||
The actual shooting (now you may raise the attention of your subject, if conditions apply) | |||
* Think in advance what the shots succession will be, what angles to focus upon; | |||
* Be flexible in your plan, if you notice the subject being well suited from a particular angle; | |||
* Give around a one second pause after the camera or the subject moves, to reach a stable shooting position; | |||
* Keep the camera steady and leveled before taking a shot, take 1 or 2 more quick shots if you suspect an unsteady hand; | |||
After taking the photos, give a cursory glance to your shots and decide if you attempt to re-take the same ones, switch to a new pose or end the session. Do not delete poorer shots yet, you would be wasting time precious time with your subject. | |||

The best way to take photos is using a tripod. Having a perfectly stable camera position makes it possible to have the best images, regardless of the type of camera you use. Any, movement, no matter how slight, reduces the clarity of the image. While all cameras have quite advanced image stabilization possibilities, you still end up with best pictures when the camera is steady. Unfortunately, tripods or stands are bulky, heavy and cumbersome. | The best way to take photos is using a tripod.

== | == Focal distance and magnification factor== | ||
Depending upon the distance from your subject and specific requirements such as emphasis on certain features, you will require different optical configurations from your camera. For a smartphone or semi-professional camera, everything will be easily set by pressing a few buttons, and you enter the specific magnification you require. For a recent smartphone, it results in switching from one of the internal cameras to another, and the new setup is immediately noticeable on the screen, as the fixed magnification factors, usually from .5 to 2x are indicated. | |||
For semi-professional cameras you press a button near the shutter and it zooms in or out the image, while the magnification factor is indicated on the screen. The closer you are, the lower the indicated value, while the further you are from the subject, the greater the required magnification factor is to reach a usable picture. Always keep in mind that the farther you are from your subject, the greater the focal length is required, the lower the amount of useful light that enters your camera and the greater the impact of even slight shaking has on your image stability. It is always the best to be right near your subject, when possible, no matter how good your camera and lens system is. | |||
On professional cameras, the magnification factor is more limited and you require physically swapping lens systems to reach the desired focal length and magnification factor to easily focus your subject. This means that, for instance, you may have a 18-45mm lens set for typical portraits, general pictures and nature ones, while you switch to a 55-210mm one for closeup on birds from far away or for capturing mountains and other natural wonders from a very large distance. | |||
Every time you resort to using focal distances on an optical system you experience specific situations that are suitable to one configuration or another, and no theoretical study will show exactly what you can do in specific circumstances. For any camera, any situation that is at the limit of focal lenses and you consistently require such a scenario, makes you, the photographer, aware that you need to compensate by changing your positioning from the subject to further compensate for a specific framing requirement. | |||
<code>''Focal lengths, magnification factors, and the way to compensate for limitations on your camera need to be experienced repeatedly and well understood. With any camera there is a learning curve to master and you need time to reach adequate results on new equipment, before changing anything once more in your setup.''</code> | |||
== Smartphone cameras == | |||
Smartphones are easily the most versatile devices. It seems that everything is obvious yet there are a lot of untapped possibilities. True photo abilities are rarely known in detail. Most of the time we rely on having everything set on AUTO and just taking a snapshot, but all phones offer much more than that. | |||
It is | === The right image format === | ||
It may seem that operating a smartphone is straightforward in this respect, just select the highest resolution in MP or megapixels. However, the best choice is far from that. As manufacturers got into a stiff competition, they tried to differentiate through less than respectable means. One such trick was to showcase a much exaggerated claim of sensor resolution. A normal approach would be, for instance, to show the real sensor resolution instead of the interpolated one. You simply cannot have a 64MP sensor in a midrange phone, when a professional camera, even at the high-end, has around 40MP. | |||
What will you achieve by using the default option of a very high resolution? As it seems, there are some minor issues. The highest resolution image does not show necessarily more detail, on close inspection, and may exhibit whitish fringes near the edges of objects. This is due to heavy contrast enhancing processing that leaves such artifacts, reaching an image that is not better from a lower resolution one while it occupies more storage space and makes editing slower. | |||
== | The best approach is to evaluate, separately, each resolution and format, on the same scene and subject, to determine which one works best. A common approach is to notice the format and resolution. Let's say at the 4:3 aspect ratio you have 64MP and 9268x6936 resolution, while at 3:4 aspect ratio you get and 16MP and 4624x3468 resolution. As a rule o thumb, the maximum resolution is never the actual sensor output and at lower resolutions the camera has a reduced risk of post-processing artifacts. Moving further up the options list, the so-called full resolution has a 4:2 format and is 4624x2084 and while the 16:9 one is 4624x2604. | ||
In this vast array of possibilities you cannot know which format is the best unless you take photos in daylight, preferably with sun-rays that are occluded by some obstacles yet shine through other areas. If there areas where the light shine brightly are under-saturated and the whole picture has little detail, you may need to select a broader image format, such as 4:2 instead of the typical 4:3 to have enough hinting on an overexposed picture and adjust accordingly. If the image has closer vertical and horizontal resolution there may be less of chance to see how far the light that affects your scene is coming from the unused sides of the sensor. This issue is much more common as you may expect while it also seems elusive, as what you don't see in the picture actually affects your end results. | |||
<code>''Understand what formats and resolution capability your smartphone camera exposes and make extensive tests in scenes that have intense light as well as relatively dim areas Try exactly the same framing on different image formats and notice which one looks better.''</code> | |||
===Wide or narrow angle shots=== | |||
With a smartphone camera you have the advantage of extensive customization and obvious, quick results but you do not have the best optics system. This is why you need to be experienced in choosing the right configuration for the task and leave some settings, that you know of, only for specific circumstances. | |||
Although it is counterintuitive, I generally suggest not pursuing neither a wider angle nor a narrow angle format, but be highly flexible in your approach. If you generally have less of an issue with scenes that show overexposure in parts of them, you can freely use a narrower angle format or a tight image format such as 4:3, while if you notice poor overall image quality you may have to switch to a wider format such as 4:2. | |||
<code>''The optics of your camera are the major limitation and you need to take into account many aspects. Experiment extensively with different setups before attempting a shot at a specific time of day or in a specific situation that you are not familiar with. It is always better to repeat annoyingly a process than to fail it altogether.''</code> | |||

It is the fastest way to end up with the best photos!''</code> | ||
=== ISO Modes === | |||
The ISO mode indicates the sensibility of your camera that is preset to account for specific lighting conditions. You use high ISO modes when taking pictures in low lighting situations, as high as 20,000 and you use low ISO modes as 100 when taking photos in bright light conditions. This means that it applies various compensations along with increasing or decreasing the exposure time to end up with useful images. Most of the time, the camera you have either does not even present ISO values when self-adjusting exposure or present these values to you as an indication of its operating range. | |||
In some particular cases, such as when you want to obtain a specific grainier look, you may artificially increase the ISO mode value, if your camera allows. Decreasing this value is not recommended as you end up with too dark pictures to be usable in most conditions. You may attempt an artistic effect on a bright direct sunlight, but it is debatable if this is worth. In the past, the ISO mode had a direct impact on image captures as specific photographic film formulation were used for typical outdoor use and others for indoor use. | |||
<code>''Most of the time, you do not need to adjust the preset ISO mode. However I highly advise you to keep track of the current active preset in some lighting conditions to determine if you are operating beyond your usual camera optimal range.''</code> | |||
=== Exposure time === | |||
All camera vary exposure time based on the scene assessments they make, but only professional cameras always expose this information, if set to do so. The exposure time can be altered by the user but it is best left as is, since successfully altering the value requires to involve changing the ISO mode, white balance and other settings. This is why you rarely need to alter the exposure time. | |||
Exposure times can be as low as 1/100 seconds, or a hundredth of a second to one as high as 3 seconds. Low exposure are typical for highly bright scenes while low ones are typical for night shots, with even higher exposure times required for sky-gazing situations. Most of the time you will be somewhere in between with your values. No two cameras will behave the same in different lighting conditions and this is also the case for different accessories such as polarizing lenses or different lens systems that may be used on your professional camera. | |||
<code>''If and when displayed, as is the case on professional cameras, the exposure time is another important hint about the camera operational conditions. In very low light situations the exposure time increases, noise and accuracy decreases, and observing the typical exposure time in different conditions can improve your shots.''</code> | |||

Some phones have a dedicated MACRO or extreme closeup mode, that operates at a distance between 2-5 centimeters from the camera. This context requires very bright lighting conditions so it is more suited to outdoor purposes. On professional and semi-professional cameras, the macro mode is, most of the time, suggested with a flower icon. | Some phones have a dedicated MACRO or extreme closeup mode, that operates at a distance between 2-5 centimeters from the main camera or a dedicated one in an array, in more modern products. This context requires very bright lighting conditions so it is more suited to outdoor purposes. On professional and semi-professional cameras, the macro mode is, most of the time, suggested with a flower icon. | ||
Professional cameras do not have a macro mode and they rely on using lens systems with short focal lengths to allow the necessary emphasis and focusing requirements on such scenes. For instance, taking a macro shot may require a 15-18mm focal length or an even shorter one. | |||
<code>''Macro most is best suited to natural environments, highlighting leafs and flower details, but it can also be used with certain ubiquitous objects from around us that may have a different meaning when pictured so close.''</code> | <code>''Macro most is best suited to natural environments, highlighting leafs and flower details, but it can also be used with certain ubiquitous objects from around us that may have a different meaning when pictured so close.''</code> | ||

While potentially appealing, panorama modes present many shortcomings due to limited abilities of phone camera lenses. Curvature aberrations are highly noticeable and lead to generally poor images. Any misalignment in successive photos or changes in light affect the final outcome. It is not recommended to use this mode except for practice purposes. With proper hinting on accurate camera positioning on subsequent shots, it can result in usable pictures that are, however, somewhat less spectacular than you may hope. For such situations, professional camera users have superangular lenses that are unavailable on other devices. | While potentially appealing, panorama modes present many shortcomings due to limited abilities of phone camera lenses.
