Welcome followers and visitors to my blog and the latest update report in my diary. One fine sunny autumn afternoon last week I set out alone on my first photoshoot with the DSLR to a local park. This was all about handling the camera and getting the feel of things in a manner of speaking and confidence building. Intermingled with my ramblings I have included here some of the images from that photoshoot.
Everything is a new challenge a new experience filled with many mistakes and missed opportunities. However I set the camera on Auto Mode and let the DSLR make the decisions. It was one of those autumn afternoons where the light was bright but no dramatic cloudscapes and the air was crisp. A great day to be outside and taking photographs.
Not only is it challenging enough to try to getting to grips with the DSLR but there is Photoshop to contend with too. So it’s not just a question of point and click for me nowadays. There are so many other factors to contend with on the camera – Aperture Values, Time Values, Film Speed, Auto Mode, Manual Mode and so on. Then in Photoshop there are Layers, Masks, DNG, JPEG, and PSD etc., etc, etc.
Although all that is enough to give anyone a headache! So it was just great to be out of doors and trying to be a photographer with the camera constantly in my hands.
Have a great day.
Welcome followers and visitors to my blog and the latest update in my diary of how I am progressing with trying to learn how to take a decent photograph with my new camera. Progress is slow but I am enjoying it. Just have to take it step by step. Unfortunately I am rather good at forgetting things!
Shutter speed, also referred to as “exposure time”, represents;
the length of time a camera shutter is open to expose light into the camera sensor.
Slow Shutter speed creates an effect called “motion blur”, where moving objects appear blurred along the direction of the motion.
Slow shutter speeds are also used to photograph lightnings or other objects at night or in dim environments with a tripod.
Landscape photographers intentionally use slow shutter speeds to create a sense of motion on rivers and waterfalls, while keeping everything else in focus.
Fast shutter speed is typically whatever it takes to freeze action.
Aperture size affects the Depth of Field in an image and which area of the image will be sharp.
A large f-number such as f/32, (smaller aperture) brings all foreground and background objects in focus.
A small f-number such as f/1.4 (large aperture) isolates the foreground from the background by making the foreground objects sharp and the background blurred and out of focus.
DSLR Camera Settings
The manual and semi-auto settings give one more creative control of a DSLR camera.
A (Av) Aperture-priority /Autoexposure
The user selects the f-stop and the camera selects shutter speed that will produce a good exposure.
S (Sv) Shutter-priority / Autoexposure
The user sets the shutter speed and the camera selects the f-stop that will produce a good exposure.
M Manual Exposure
The user controls both the shutter speed and f-stop.
The common shutter speeds are:
1s 1/2s 1/4s 1/8s 1/15s 1/30s 1/60s 1/125s 1/250s 1/500s 1/1000s 1/2000s
Fast shutter speeds such as;
1/250s will freeze faster moving subjects, depending on their speed of movement.
Slow shutter speeds such as:
1/30s and slower will create motion blur with moving subjects, depending upon their speed of movement.
One has to remember that depending on the choice of lens one should ideally select a shutter speed of at least 1/60s to prevent camera shake without using a tripod.
So much to remember! So Easily forgotten!!
