If you have the DSLR camera or equivalent, then you may constantly be thinking about shutter speeds and apertures.  Which way should I lean?  Should I use this aperture, or should I use this shutter speed, etc.   So much to think about if you really want to be artistic in your photography.  But, it’s worth it to know and learn all you can about this subject.  I know I have posted  and published articles before about both these subjects, but, I liked this article because it talks about the relationship between the two.  It’s worth looking at and reading about so you can improve your photography.  The article is written by:  Joe Watson.  His insight is really good, and I hope you get something from this article.

SHUTTER SPEED AND APERTURE

Understanding the relationship between aperture and shutter speed will help you take full advantage of your DSLR, allowing you to have more fun capturing photos. The aperture is the size of the hole in the diaphragm of the lens. It is possible to view this device when you look right square into the lens of the camera. The aperture diameter (size of the hole) is denoted by a sequence of f-numbers. The DSLR’s digital screen will display the aperture size, as well.

The smaller the f-number, the larger the aperture (hole), and consequently, the larger the f-number, the smaller the aperture. Every time you widen up one step (f/5.6 to f/2.8, for example), you allow in twice the amount of light. Reduce one step, and you let in half the amount of light. For illustrations of the actual aperture in the lens and its relationship to the f-stop numbers, go to my site, the link is at the bottom.

 EQUIVELANT EXPOSURE:

OK, so we know that aperture is the size of the opening in the lens where light enters, but how do you apply it to capturing images? Photography is all about getting the correct quantity of light for a given picture. At f/22, which is a very small aperture, less light will hit the image sensor compared to a picture taken at f/1.4, which is a very big opening. Keep in mind, though, that this is assuming the shutter is open for the same amount of time.

But you can get the identical exposure at f/22 as you can get at f/1.4 by simply lengthening the shutter speed, which causes the shutter to be open for more time, allowing more light in. Aperture and shutter speed settings combined allow a desired quantity of light to be exposed to the image sensor. Different combinations of f-stops and shutter speeds can achieve identical results in exposure. For example, f/8 at a shutter speed of 1/30, which will open the shutter for 1/30 of a second, will result in the same exposure as f/16 (smaller hole) at a shutter speed of 1/8 of a second. This is known as equivalent exposure.

ARTISTIC CONTROL:

Knowing that you can get the same exposure values using different combinations of f-stop and shutter speeds is one thing. Knowing when to use them is something else. Just because you will be able to get the same exposure does not mean that your image results will be the same. This is where the art of photography comes in.

Do you want a sharp image or some blur? Do you want everything possible in focus or just the subject? Once you decide the answers to these questions you can choose your settings for aperture and shutter speed.

DEPTH OF FIELD:

Shutter speed settings and the effects they have on your image are not too hard to understand. The longer the shutter is open (slower shutter speed), any objects that are moving in the field of the image will appear more and more blurred. Remember, though, that the subject doesn’t have to be the one moving to result in a blurred image. A slow shutter speed with a shaky hand can blur a picture as well. This is why a tripod is a good idea–and sometimes mandatory–for shots with slower shutter speeds. Aperture has an effect on something known as “depth of field”. The smaller the f-stop, which widens the diameter in the lens, the less depth of field. Consequently the bigger the f-stop, which shrinks the diameter of the hole in the lens, the more depth of field. The more depth of field, the sharper all objects in the field of view. With less depth of field, only the subject in focus will be sharp.

PUT IT TO USE:

It is not difficult to start experimenting with aperture and shutter speed and start getting quality results. Even the least expensive DSLRs on the market today have the tools necessary to aid beginner photographers when it comes to taking pictures on settings other than auto. Decide what type of picture and effect you want.

For the first example, we will use a candid portrait of a person’s face. The desire is to have the face fill the shot and to be the main focus point of the image. To obtain this result, put your camera on Aperture Priority mode. This is a setting that gives you control over the aperture while the camera takes care of shutter speed on its own. Now that you are in control of the aperture, go ahead and open it all the way. Focus on the subject’s face and take the shot. In taking this shot, you have reduced the depth of field so that only your subject’s face is in focus, blurring most everything else out.

I will use a landscape photo for the next example. Landscape photos require maximum depth of field. Put your camera on Aperture Priority mode like the example above. But this time, close or narrow the aperture all the way. Now that the aperture is very tiny, the camera will compensate on its own by forcing the shutter to stay open longer to get the right exposure. The result of this can lead to a blurred image, so a tripod is recommended.

For a final example, I will use a sporting event. This time, utilize the Shutter Priority setting on your camera. Shutter priority allows you to set the shutter speed on your own while the camera compensates for exposure by setting its own aperture. A cool technique to try is to slow the shutter speed down and take shots of the subjects running, jumping, etc.. The trick is to follow the subject with the camera while taking the shot at a slow shutter speed. If you are smooth about it, you will get a result that shows the subject mostly in focus but everything in the background blurred with motion. This will give the sensation of movement and speed in the photo. It’s not easy to achieve desired results, so take a lot of pictures.

What you want to do is try out these different techniques as often as you can. Get used to taking shots on settings other than full auto mode. Only once you get comfortable with the different camera settings and the relationship between aperture and shutter speed will you start to unlock the full potential of your DSLR camera.

Happy Shooting!

DxOMark tested the Nikon D3400 camera ($496.95) and called it a “new class leader”. Here is their conclusion:

As an entry-level APS-C model, the Nikon D3400 is difficult to beat in terms of sensor performance. Nikon has tweaked the sensor to the same level as the pricier D5500. However, except for the SnapBridge connectivity option, the D3400 is very close to that of the older and cheaper D3300, in terms of features and controls. While the bump in image quality is welcome, it’s not as though the D3300 was underperforming in any way, at least when compared with its rivals. But packaged with a new AF-P type kit lens that promises improved AF in live view, the D3400 is a step in the right direction.

Boldly different: Leica presents the TL-System

Unique design in titanium, silver or black finish, combined with precise, high-performance lenses and a host of smart accessories

Leica Camera has today announced the Leica TL. Building on the Leica T camera system, which has been continually enhanced in terms of speed, handling and flexibility since its launch in 2014, the new generation Leica TL now offers further innovative features, improved functionality, and a series of exciting new design elements.

Developments include the doubling of the internal buffer memory to 32GB, improved autofocus, particularly in AF-C mode, and optimised compatibility with lenses from other camera systems in the Leica range.  For example, the Leica TL now supports SL-Lenses with OIS and allows the use of Leica R-System lenses in combination with the R-Adapter L. A new Leica TL app with added functionality provides additional options for sharing pictures by email or on social networks, and is now available for the first time for Android, as well as iOS devices.

The Leica TL will in available in three colour options from the date of launch: the silver and black versions share an identical design and construction, while the titanium finish option is distinguished by a bevelled edge detail to the top and bottom plates. A collection of smart camera accessories, such as a new range of high-quality protectors in Nappa leather, which are designed to remain on the camera when changing the battery, and a selection of matching carrying straps in stone grey, black, red and cemento, complete the TL system portfolio.

Combined with its high-performance image processor, the large, APS-C CMOS image sensor of the Leica TL guarantees exceptional imaging quality and delivers brilliant pictures with outstanding contrast, detailed resolution and natural colour rendition – even in unfavourable lighting conditions.

The comprehensive Leica TL lens portfolio offers a wide choice of focal lengths for all photographic situations and genres. The TL-System currently comprises six lenses – three prime lenses and three zooms. The two fast prime lenses, the Leica Summicron-TL 23mm f/2 ASPH. and Summilux-TL 35mm f/1.4 ASPH., are classic focal lengths for reportage photography, and the APO-Macro-Elmarit-TL 60mm f/2.8 ASPH. is perfect for finely detailed close-up photography. The three compact zoom lenses, the Leica Super-Vario-Elmar-TL 11–23mm f/3.5–4.5 ASPH., Vario-Elmar-TL 18–56mm f/3.5–5.6 ASPH. and APO-Vario-Elmar-TL 55–135mm f/3.5–4.5 ASPH., cover an entire range of focal lengths equivalent to 17 to 200mm in 35mm format and deliver outstanding images with rich contrast from corner to corner of the frame.

Developed by Leica’s optical design specialists in Wetzlar, all Leica TL-Lenses deliver exceptional imaging performance at all distances from their close focusing limits to infinity, resulting in pictures with the inimitable ‘Leica look’ and unique bokeh. The combination of expert optical and precision engineering, and the use of the finest materials in their construction, ensures the consistent high quality and reliability of the lenses.

Thanks to the L-Bayonet mount shared by the Leica TL and SL cameras, SL-Lenses can also be used without an adapter on the Leica TL, once again highlighting Leica’s commitment to system compatibility and sustainability. Furthermore, adapters are available to enable the use of Leica M and R lenses on the camera.

A particular highlight of the Leica TL is the unusual, compact design of its body, which is precisely machined from a single block of aluminium at the Leica factory. Meticulous construction from the most premium materials gives the Leica TL its unique, unmistakeable look and solid, high quality feel.

Offering concise, intuitive handling, and a focus on the most relevant functions, the Leica TL ‘control centre’ is clearly laid out on the 3.7” touchscreen display, which delivers a clear, bright image for precise and reliable subject composition and review.

Numerous functions in capture and playback mode can be controlled simply by touching the screen. Four ergonomically-positioned haptic controls, which are highly intuitive in operation, ensure that photographers can concentrate fully on composing their images – with no unnecessary distractions. The configurable MyCamera menu offers further flexibility, even in spontaneous shooting situations, giving the user the quickest access to the most frequently used features and personalised pre-sets.

Thanks to its integrated WiFi module and mobile hotspot feature, the Leica TL can conveniently transfer still images and videos by WLAN to smartphones, tablets, laptops or desktop PCs from almost anywhere, and allows users to share their pictures and movies by email, on Facebook or on other social networks.

The free Leica TL app for iOS and Android devices is available with the release of the camera. A particularly useful feature of this app is the remote control function, which enables the user to connect a smartphone or tablet to the camera by WLAN as an electronic viewfinder for the Leica TL, and provides remote control of shutter speed and aperture settings – ideal for shots taken at unusual angles, or for use with the self-timer.

Pricing and availability

The Leica TL in black, silver or titanium anodised finish is scheduled to be available from mid-November 2016, at a suggested retail price of £1,450 including VAT.
