Inorganic (Close-up / Macro) Click West Topic
An image which displays detail not usually observable by the human eye of an inorganic subject.
Explore what are inorganic subjects or objects, glass, architectural forms, concrete, steel etc., your imagination and observation are the key to selecting a subject.
Inorganic objects combined with close-up or macro applies itself very well to representing an object or structure in an abstract form.
Abstract photography doesn’t present a subject in a literal way. It communicates more through form, texture and colour. This can offer photographic freedom. Yes, do not forget to use colour as part of the composition.
Sharp, artificial lines indicate a feeling of immediacy or modernity. Vertical lines lend solidity to an image. And horizontal lines emphasise balance and depth.
With so many uses, investigating line in abstract photography is a must. Next time you head out shooting, concentrate on finding lines. Then incorporate them into your photography ideas.
Try focusing on architectural and urban elements for photography ideas. Strong, bold lines are more abundant in artificial landscapes.

See how many different types of lines you can find. Curvy, straight, coloured, bold – once you start looking, possibilities abound!
Having just talked about colour, there is of course another option: removing colour altogether! Without colour, the eye looks for alternative visual references in an image. That’s why black and white photography is a great way to isolate shape and form.
It also accentuates the light and shadow of an image, creating more depth with contrast.

After Sunset / Before Sunrise (Landscape) Click West Topic
An image about an environment, natural or manmade, captured after the sun has set or before it has risen. A portion of the sky must be visible in the image. People and/or animals maybe included but must not be the subject or dominate the scene.
The hour or so before or after the sun sets is known to photographers as the “golden hour” and also the “blue hour” after sunset.
Photos captured during this time often take on a blue hue (although that can be manipulated). It depends on the sunset and the landscape, but after sunset there is almost always a much larger variation of colour in the sky – from warm hues of oranges, reds and yellows in the clouds and atmosphere from sunlight reflected over the horizon to cool colours of blues, magentas and purples from the approaching night.
However, the interesting thing is that these colours can be subtle – so subtle in fact that to the eye, you often can’t even tell that they’re there – which is why people usually put away their cameras away after the sun sets.
The exciting result is that you might not even know how your photos are going to turn out until after you process them – and by process, I mean digital processing with Lightroom or Photoshop. You will always be amazed how often a grey, dull, boring looking blue hour photo that I thought was a throw away turns out to be a really awesome surprise
The use of filters, Graduated ND filters or with a coloured hue can also assist with enhancing and assist with correct exposure.
Consider: The temperature and colour of the sky during the golden hour will change by the minute. As you shoot, you’ll get more of that unnatural yellow undertone in your images. Instead of choosing between fixed white balance options like Fluorescent, Daylight, Cloudy, or even Auto, you’re better off setting your white balance manually so you can get the colours in your photos as accurate as possible.

What is an inorganic material?
Is concrete organic or inorganic compound?
Concrete is, I think inorganic.
How do organic and inorganic compounds differ?
In general, organic compounds / substances / materials contain carbon atoms bonded with other atoms and/or those related to life. It is the chemistry of carbon containing compounds. Inorganic is everything else and generally do not contain carbon (with some exceptions). For instance, steels contain carbon but it is inorganic, tungsten carbide for example.
What are organic and inorganic compounds?
In general, organic compounds / substances / materials contain carbon atoms bonded with other atoms and/or those related to life. It is the chemistry of carbon containing compounds. Inorganic is everything else and generally do not contain carbon (with some exceptions). all compounds which are having all compounds which are having carbon and hydrogen essentially in molecular formulas are called organic compounds. These may have any other element also.eg; CH3COCH3 (Acetone)
Compounds having only carbon and hydrogen are called as hydrocarbons. they are also a class of organic compounds.eg; CH4 (methane)
Any other compound which do not have either of carbon & hydrogen is called as inorganic compound.eg; CO2, H2O are inorganic compounds

How do organic compounds differ from inorganic compounds?
Organic compounds are based on carbon as an essential element; but now this rule is not absolute.
Is plastic a organic or inorganic compound?
organic, simply because it contains carbon. plastics are hydrocarbons. They do not, for the most part, biodegrade. Recently "Organic Plastics" have been introduced, which are made from renewable sources, not petroleum/fossil fuels. This article explains a bit about it: www.thomasnet.com/a… (MORE)
Is salt an organic or inorganic compound?
Salt (Sodium Chloride, NaCl) is an inorganic compound. The classification of an organic compound is that it is a molecule that contains a carbon atom. Everything else can be considered inorganic. Some molecules that contain carbon are also inorganic such as carbon dioxide or calcium carbonate.
How are organic and inorganic compounds different?
Basically, all organic compounds have carbon and organic chemistry is the study of carbon-based compounds. Inorganic generally do not contain carbon (with exceptions being carbon monoxide, carbon dioxide, metal carbonates, metal bicarbonates and metal carbides).
Is cellulose an organic or inorganic compound?
Cellulose is an organic compound used to transform water although the cell is being protected by a cell membrane
How do you tell if a compound is organic or inorganic?
That depends. An organic compound has elements made from nature itself. An inorganic is the opposite meaning that it is made from compounds and elements that are not made from nature itself, more or less, it's kind of like manmade compounds.
Differentiate of organic and inorganic compound?
An organic compound is something that is alive, or was once alive, or was part of something that was living. Inorganic means that it was never alive, or was never a part of something alive. Example: Steak: Organic. Boiling hot lava: Inorganic.
Is water an organic or an inorganic compound?
Water (H 2 O) is an inorganic compound. An organic compound has to contain carbon atoms (but this is not a general rule - many inorganic compounds contain carbon). Organic compounds, by definition, must contain carbon atoms. Water is an inorganic compound because it is composed solely of hydrogen… (MORE)
Is rust an organic or inorganic compound?
If rust is a compound at all, it is an inorganic compound (Fe 2 O 3 ), because contains has no carbon and is not a derivative of a hydrocarbon.
Is C3H5OH a organic or inorganic compound?
It is an organic compound, CH 2 =CH-CH 2 OH. However it's more likely you have meant C 2 H 5 OH which is ethanol (standard alcohol), also organic.
How do the inorganic and organic compounds differ?
Traditionally organic compounds are considered compounds containing carbon; but a rigorous boundary doesn't exist - some inorganic compounds (as carbonates, carbides, cyanides etc.) contain also carbon.
