3 pillars of photography

Let give a try in understanding 3 pillars of photography.

1.  Aperture

2.  Shutter Speed

3.  ISO

Aperture:
In optics, an aperture is a hole or an opening through which light travels. In photography, aperture is a hole within a lens, through which light travels into the camera body. The iris of the lens that controls the size (diameter) of the aperture is called “diaphragm” in optics. The sole purpose of the diaphragm is to block or stop all light, with the exception of the light that goes through the aperture. In photography, aperture is expressed in f-numbers (for example f/5.6). These f-numbers that are known as “f-stops” are a way of describing the size of the aperture, or how open or closed the aperture is. A smaller f-stop means a larger aperture, while a larger f-stop means a smaller aperture. Most people find this awkward, since we are used to having larger numbers represent larger values, but not in this case. For example, f/1.4 is larger than f/2.0 and much larger than f/8.0

Shutter Speed:
In photography, shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph.[1] The amount of light that reaches the film or image sensor is proportional to the exposure time. 1/500th of a second will let half as much light in as 1/250th

ISO:
In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain.

Shoot modes in DSLR

Having a good understanding of the digital camera modes is essential to control the exposure in photography. Whether you are a beginner or an advanced amateur, you should know what each camera mode does and when it should be used, under what circumstances.

P : Program Mode

In “Program” mode, the camera automatically chooses the Aperture and the Shutter Speed for you, based on the amount of light that passes through the lens. This is the mode you want to use for “point and shoot” moments, when you just need to quickly snap a picture. The camera will try to balance between aperture and shutter speed, increasing and decreasing the two based on the intensity of light

S: Shutter-Priority Mode

In “Shutter Priority” mode, you manually set the camera’s shutter speed and the camera automatically picks the right aperture for you, based on the amount of light that passes through the lens. This mode is intended to be used when motion needs to be frozen or intentionally blurred. If there is too much light, the camera will increase the lens aperture to a higher number, which decreases the amount of light that passes through the lens. If there is not enough light, the camera will decrease the aperture to the lowest number, so that more light passes through the lens. So in Shutter Priority mode, the shutter speed stays the same (what you set it to), while aperture automatically increases and decreases, based on the amount of light. In addition, there is no control over subject isolation, because you are letting the camera control the depth of field.

A : Aperture-Priority Mode

In “Aperture Priority” mode, you manually set the lens aperture, while the camera automatically picks the right shutter speed to properly expose the image. You have full control over subject isolation and you can play with the depth of field, because you can increase or decrease the lens aperture and let the camera do the math on measuring the right shutter speed. If there is too much light, the camera will automatically increase the shutter speed, while if you are in a low-light environment, the camera will decrease the shutter speed. There is almost no risk of having an overexposed or an underexposed image, because the shutter speed can go as low as 30 seconds and as fast as 1/4000-1/8000th of a second (depending on the camera), which is more than sufficient for most lighting situations.

This is the mode that I use 95% of the time, because I have full control over the depth of field and I know that the image will be properly exposed under normal circumstances.

M : Manual Mode

As the name suggests, “Manual” mode stands for a full manual control of Aperture and Shutter Speed. In this mode, you can manually set both the aperture and the shutter speed to any value you want – the camera lets you fully take over the exposure controls. This mode is generally used in situations, where the camera has a hard time figuring out the correct exposure in extreme lighting situations. For example, if you are photographing a scene with a very bright area, the camera might incorrectly guess the exposure and either overexpose or underexpose the rest of the image. In those cases, you can set your camera to manual mode, then evaluate the amount of light in darker and brighter areas and override the exposure with your own settings. Manual mode is also useful for consistency, if you need to make sure that both shutter speed and aperture stay the same across multiple

Types of Cameras in Photography

Types of Cameras for Photography

• Compact Digital Camera(Point and shoot)
• Bridge cameras (Super Zoom Camera)
• Digital SLR Cameras
• Mirrorless Cameras
• Action Cameras

Compact Digital Camera:
 

Point and shoot cameras are very famous and user friendly digital camera. It allows anyone to capture beautiful pictures/photos by simply pointing the camera at subject and click the shutter button. Due to compact size we can carry very easy when you're going for holidays and trips.

Pros:

• Very user-friendly
• Light and compact
• Expandable memory
• No need invest on lens's
• Full auto mode
• Less expensive

Cons:

• No manual operations
• Limited zoom range
• Lower resolution
• Delay in focus

Bridge Cameras:
 

Bridge cameras are cameras that fill the niche between the DSLR and the point-and-shoot camera. They are also called as superzoom cameras.  The term "bridge camera" was originally used to refer to film cameras which "bridged the gap" between point-and-shoot cameras and SLRs.

Pros:

• No need invest on lens's
• Very user-friendly
• Light and compact
• Full auto mode
• Cheaper then DSLR's
• We can shoot in RAW

Cons:

• Usually can’t customize shutter speed and aperture
• Limited aperture and fixed zoom range
• Lower resolution due to small sensor
• Slower focus

Digital SLR Cameras

DSLR (or digital single lens reflex) cameras take photos to the next level of image quality. This more “serious” type of camera is best known for delivering remarkably sharp and spectacular images, with beautiful background bokeh, and even high resolution videos with the help of their advanced sensors, manual settings, and wide range of interchangeable lenses.

While they are considered high-end, there are more affordable entry-level DSLRs for beginners. They are suitable for almost every kind of photography out there, so literally anyone—from hobbyists to event and sports photographers—can opt for this type of camera.

1. Camera lens

2. Reflex mirror

3. Focal-plane shutter
4. Image sensor

5. Matte focusing screen
6. Condenser lens

7. Pentaprism/pentamirror
8. Viewfinder eyepiece

DSLR of two types: full-frame and crop sensor

Pros:

• Fully customizable settings
• Large sensors for cleaner images
• Optical viewfinder
• High-resolution photo output
• Full HD to UHD video output
• Wide variety of camera body and lens choices

Cons:

• Bigger and bulkier
• Higher cost
• Requires ample know-how

Mirrorless cameras

This are the latest in professional cameras—they are basically more compact DSLRs without the internal mirror that reflects light onto the sensor.

What’s interesting about mirrorless cameras is that they are now capable of capturing incredible, high-resolution images with even faster shutter speeds and record ultra HD videos that only the most expensive, higher-end DSLRs can produce.

The main reason why many still prefer DSLRs, however, is that they have access to a bigger collection of lenses. However, mirrorless cameras are great investments considering their growing collection of lenses.

Overall, it’s a combination of two popular types of digital cameras—a point-and-shoot for its compact size and somewhat simpler controls, and a DSLR for its interchangeable lenses and impressive output.

Similar to the DSLR, mirrorless cameras also come in two types: full-frame and crop sensor

The Very First Mirrorless Camera Was a Gem Made by Epson in 2010.

Pros:

• Electronic viewfinder
• Smaller and lighter
• Simpler operation and controls
• Faster and better for video
• Higher video quality even in lower-end models
• Shoots more images at faster shutter speeds

Cons:

• Shorter battery life
• Slower autofocus
• Fewer lenses and accessories

Action Cameras

We’ve definitely seen the rising popularity of action cameras in the past few years, and it’s not hard to see why. Common action cameras like the GoPro can fit in the palm of your hand, but they’re some of the most durable and versatile types of digital cameras that offer very high-resolution output.

If you’re the adventurous or sporty type and simply want to take breathtaking photos and videos that will “take you back” to those moments, action cameras are for you.

Pros:

• Rugged and compact
• Lightweight
• Versatile and mountable on almost any surface
• Remote view and shutter via smartphone

Cons:

• Viewfinder too small, if available
• Exposure settings not fully customizable
• Fixed focus
• Limited digital zoom

Gearbest.com Sucks

Being an online shopper, I have satisfactory and worse experiences, so I'm here to talk about a website called "www.gearbest.com"

Gearbest is a Chines website, here are pros and cons:

Pros:
1) You can expect cheap and non-guaranteed products.

Cons:
1) Very worse customer support.
2) Long shipping period.
3) Return policies are like HELL
4) 

My final conclusion is not buy any product from Gearbest.com website which more then 25$, so that you will wont feel bad if things turn around 

Xiaomi Redmi fake Sales on Flipkart

Xiaomi is losing the customer with their “Redmi phones” fake Sales on Flipkart. 

Xiaomi is doing worse business tricks to increase new model sales by releasing fake sale on successes models like "Redmi 3s/3s Prime".

Here is the case:

A customer wanted to buy "Redmi 3s" from Flipkart, in product description there is a message saying "Next Sale on Friday 5th May at 12 Noon. Stay Tuned!" but when customers tired to book on very accurate time like "5th May 12:00:30", "Coming Soon..." message turned to "Out of Stock"

It's not the just case of one or 2 times, several customers tried for may times and posted their bad opinions on few forms, maybe "Flipkart" or "Xiaomi" should take few things serious which will impact the lose of customer's.

No luck with today's(12th May) sale as well.
