5 Resons I'm excited about the Sony A7 and A7r Mirrorless Cameras

Here are the 5 reasons why I'm excited about the Sony A7 and A7r mirroless interchangeable lens cameras with full frame sensors.

1. Specifications - Regardless of the camera, there is no denying that the specifications of the Sony A7 and A7r are top notch.
2. Size - Sony was able to cram in tons of features in to a camera as small as competing micro 4/3 cameras. A huge accomplishment in itself.
3. Price - The Sony A7 and A7r come in at a fraction of the cost of their closest competitors (in terms of specs), the Nikon D610 and D800e
4. Adapting legacy lenses - The full frame sensor on these mirrorless cameras allows you to use old lenses of a capturing medium that is the same size as the one that they were build for. Your old lenses are no longer obsolete.
5. Effect on the camera market - There is no doubt that the Sony A7 and A7r are going to shake up the camera market. We're going to see new technology, better/more comfortable form factors and lower prices. DSLR manufacturers are going to have to find ways to differentiate themselves from the mirrorless camera market.

Depth of Field in Photography

Depth of field is how much of your image is in acceptable focus. A large or deep depth of field means that a lot of your image, beyond the point of focus, is in focus. A small or shallow depth of field means that very little of your image, apart from your point of focus, is in focus.

Depth of field is controlled by three things: aperture, subject distance from the camera and focal length.

Aperture and Depth of Field

Aperture is the first factor that affects depth of field, and is the one that many people are already aware of. Larger physical apertures, or smaller f-stop values, gives you smaller, or shallower depth of field. A smaller physical aperture, or larger f-stop value, will give you a larger or deeper depth of field. This means that a large portion beyond your focus area will be in acceptable focus.

Subject Distance and Depth of Field

Subject distance from the camera is the second factor that affects depth of field. The closer your subject is to yore camera, the shallower your depth of field will be (assuming that your focal length and aperture stay constant). This is because the planes of focus get thinner as you get closes to the camera. When your subject is further ways from your camera, it's harder to get shallow depth of field.

Focal Length and Depth of Field

Focal length is the final factor that affects your depth of field. Wider focal lengths give you less depth of field at equivalent aperture and subject distance than a long lens would. Longer lenses compress your scene and push your background further back.

Depth of Field and Bokeh

I often head Depth of Field and Bokeh being used interchangeable, which shouldn't be the case. Depth of field is the amount of image beyond your focus point that is in focus. Bokeh is a Japanese word that literally translates to "blur". Bokeh refers to the actually out of focus area of your image, not what is in focus.

Using Your Camera's Built-in Light Meter in Manual Mode

Camera's have many tools to help you figure out what your exposure should be, and this includes the built-in light meter. Your camera's light meter helps you get proper exposures when you're taking a photograph.

The light meter is not only operational during your automatic and semi automatic exposure modes, but in manual exposure mode as well. The video above will guide you in using your light meter to get the exposure that you want.

The light meter reads light differently based on the metering mode that you set it to. You can read more about that here.

Camera Metering Modes in Photography

Your camera has a built-in light meter to assist you in reading the light or a particular scene. The light meter reads the amount of light in your frame, balances that light out to middle gray and give you what it thinks is the proper exposure.

The camera has different metering modes to change the way in which it reads the light. Cameras usually come with three different metering modes and these three modes might have different names depending on the brand of camera that you are using, but they are pretty much standard.

Evaluative Metering

Evaluative metering is what your camera is stet to by default, and it is what I recommend to those of you that aren't comfortable changing your metering modes just yet. The evaluative meter will measure the amount of light present in your entire frame. It will then balance that light out to middle gray to give you what it thinks is the proper exposure.

Center-Weighted Metering

Center-weighted metering only meters the middle area of your scene and ignores the rest of the frame. This is particularly good when you want to meter a subjects and not the background. In situations when you have strong backlight, the evaluative meter gets tricked into thinking your subject is over exposed and end up capturing it as a silhouette. Center-weight metering can be used to make sure that you only meter your subject.

Spot Metering

The spot metering mode meters the very center point of your scene. This metering mode is useful when there is a particular area of your photo that needs to be metered perfectly. If you have a area of a persons skin, for example, that you want ensure that it doesn't get blown out, you can align the center of your frame to that portion of the skin, set your exposure to the given meter reading, and recompose to take the picture. That way, the skin that you metered will be properly exposed.

Conclusion

The three common metering modes in your camera all help you to produces images the way you want them to look, so learning about them is crucial. Once you get comfortable using them, they will become second nature and a natural part of your workflow.

Autofocus Modes in Photography

There are usually three different autofocus modes available in your camera: Single shot autofocus, continuous autofocus and intelligent autofocus. These three different autofocus modes are there for use in different situations.

Understanding Exposure and The Exposure Triangle

Exposure

Exposure is the amount of light that is recorded on your image sensor or film. There are three things that affect your exposure when you're taking an image - your aperture, shutter speed and ISO. These three things all affect the amount of light that your sensor capture, but they also have secondary effects.

Aperture controls depth of field.
Shutter speed controls motion blur.
ISO controls sensor sensitivity and noise in images.

Balancing these three things is the key to making good images.

What is ISO in Photography?

ISO is your sensors sensitivity to light. Low ISO values (e.g. ISO 200) make the sensor less sensitive to light, which means that you would need more light to expose an image than you would need if you use a higher ISO value (e.g. ISO 1600).

Back in the days of film, you could only use one ISO at a time and that was the ISO of the film that you were using. With digital cameras, we have the ability to change out ISO on the go depending on the lighting conditions that we are in.

Low ISO (ISO 100) - Accurate colors and free of noise

ISO also affects the amount of noise that you have in your image. Digital noise are the random specs of colored pixels that you see in some images. The higher your ISO is, the more noise you will get in your images, which is why it is not ideal to raise your ISO more than you have to. Using higher ISO values will also skew how your colors look, making them look a lot duller than what is actually there.

High ISO (ISO 3200) - Noise is introduced and colors are not acurate 

When given a lot of light, you should use the lowest native ISO that you can. Increase your ISO when your shutter speed and aperture are at the point where you do not what to change them anymore. The ISO is usually that last thing that you'll change out of the three things that affect your exposure.

What is Shutter Speed in Photography?

Fast Shutter Speed (1/500th of a Second) - Action is Frozen

Shutter speed is the amount of time in which your exposure takes place for. The longer your shutter speed is, the more light hits the sensor. The faster your shutter speed it, the less light hits your sensor.

Shutter speed also affects motion blur in your shots. To freeze action, you'll want a fast shutter speed. Using a fast shutter speed will ensure that your subject will be tack sharp when you take your photo. Using a fast shutter speed will also ensure that any camera shake is not recorded because of how quick the exposure is.

Slow Shutter Speed (25 seconds) - Car Light Trails

Slow shutter speeds will show motion blur. While most people will want to get tack sharp images with their subjects frozen, there are times when slow shutter speeds can be used to create successful images. When you want to show movement in a shot, you might want to slow down your shutter speed a little so that you can see the motion of your subject. Other popular techniques using slow shutter speeds include capturing light trails and making water look silky smooth. When you slow down your shutter speed, camera shake will be introduced. To avoid this, a tripod is recommended for those longer exposures.

Slow Shutter Speed (1.3 seconds) - Shows Movement

Of course, you'll also have to take into account your aperture and ISO when taking a photograph.

What is Aperture in Photography?

Aperture is the physical opening of the lens

Aperture is defined as the physical opening of your lens. A large aperture lets more light into your camera than a smaller aperture would. The aperture is measured by f-stops. Larger f-stop numbers (f/16) signify a smaller physical aperture. Smaller f-stop numbers (f/2) signify larger physical aperture. F-stops and aperture size can be a little bit confusing at first, but you'll get the hang of it pretty quickly.

Large Aperture / Small f-stop (f/1.8) - Shallow Depth of Field

Asides from controlling the amount of light that enters the camera, your aperture also helps to control your depth of field. Depth of field is how much of your image is in acceptable focus. Larger physical apertures, or smaller f-stop values, gives you smaller/shallower depth of field. This means that less of your image beyond your focus area will be in focus. A smaller physical aperture, or larger f-stop value, will give you a larger/deeper depth of field. This means that a large portion beyond your focus area will be in acceptable focus. 

Small Aperture / Large f-stop (f/7.1) - Deep Depth of Field

Of course, you'll also have to take into account your shutter speed and ISO when taking a photograph.

Wacom Intuos Pen and Touch (2013) Unboxing and First Impressions

Wacom has made a lot of changes in the naming of their products and this includes the introduction of the new Wacom Intuos line of tablets, replacing the former Wacom Bamboo Tablets (the Bamboo name has now been designated to other products). This new lineup of pen tablets includes two Intuos Pen and Touch models (a small and a medium size), a Pen only model that comes in the small size and an Intuos Manga model (Pen and Touch bundled with different software). The new Wacom Intuos line is very similar to the outgoing Bamboo models, but Wacom has made a few changes in build quality and in features that make these new tablets appealing to those that are getting their first tablets.

The New Home of CamCrunch

Welcome to the new home of CamCrunch! After numerous problems with Wordpress, I've decided to come back to Blogger. I'll be developing the website over here for now. If the site ever grows to the point where Wordpress is needed again, I'll move it back over to that platform. For now, I think Blogger will be mere than enough to keep this site moving forward.
