Why Does It Still look Blurry After Using the Manual Focus and Adjusting It


By Arindam Roy

The first thing to do is to correctly adjust the aperture. The reason why it looks blurry may be that the aperture is not big enough for your lens. If you have a lot of light in your scene, then the aperture should be set smaller than if there’s not much light. Adjusting the shutter speed and ISO will also affect how clear photographs are.

There are many steps that can be taken to fix blurry pictures but it’s important first to identify what’s causing them in order to find an effective solution. If you find your images are blurry after fine-tuning your settings, then it could be that you need to do some adjusting. Changing the aperture, ISO, or shutter speed can change how a shot is exposed.

But if you find that you’re consistently getting blurry shots, there are several things to look for when trying to figure out why.

 

Problems with focusing

 

Film cameras have a distance scale built into the lens mount itself. The distance scale shows how far away the object in the picture is from the camera and is used by autofocus systems in AF-S lenses and lenses with other types of coupling.

In manual focus, you don’t have the benefit of this distance scale to figure out if the focus is in range or not. If you’re trying to focus on an object that is close up, like a person, and the camera isn’t focusing correctly on what you want it to, then there are three solutions.

 

  1. First, it could be that the lens needs to be cleaned. A dirty lens can cause blur in pictures. Use a microfiber cloth or a cleaning product formulated for lenses to clean it.
  2. The second solution is using autofocus settings on the camera itself. Rotate the dial on the camera body until it says “A-F” or “M-A.” This will switch from autofocus to manual focus.
  3. The third solution is to use an adapter for a modern AF lens that will provide focusing distance by displaying it in the viewfinder or LCD screen of the camera. This can vary depending on how much you’re willing to spend and what specific adapter you buy, but they do exist.

Problems with shutter speed and ISO settings

 

If your pictures are blurry because of exposure, which is to say light is getting in the way, then there are two things you need to solve: shutter speed and ISO. Two things affect exposure: the size of the aperture opening and how long you leave the shutter open to let light in through it.

Once you know how much light is coming into the camera using the exposure triangle, then it’s time to figure out if your photograph is over or underexposed using a histogram. A histogram will measure how dark or bright a picture is and show where each part of it is on a graph.

If your image has blown-out highlights (the very brightest parts are pure white) or blocked-up shadows (the lowest brightness part of an image is pure black), then you need to change settings. If you want, you can use a photo calculator to figure out how much change you need to make.

For example, if the image is overexposed by one-third of a stop (one-third of a stop of underexposed), then it would need to be one stop underexposed. If the image is underexposed by two stops, it would need to be two stops overexposed.

Next time you’re out shooting photos in harsh sunlight and find that your photographs are blurry, try using an ND filter or lowering your ISO and see if it helps at all. This could be an indication that the camera wasn’t focusing properly or that images were not exposed properly.

If you’re still having trouble with exposure, make sure that you’re not getting multiple images of the same shot because of shutter speed. If you are, try setting the shutter speed to a higher number or using a tripod to help stabilize the camera.

Problems with lens quality

 

If everything else is set properly and your image is still blurry, it may be that your lens just isn’t as good as it could be. Modern lenses are made with “elements” which are individual pieces of glass inside of them. The greater number of these elements on a lens, the better quality it tends to be.

For example, a lens with 7 elements instead of 6 will have higher quality than one with 8. In the world of lenses there is a general rule called the Rule of Thirds. This rule states that 60% of the image should be composed in the center and 30% should be on either side depending on where focal length is measured.

The Rule of Thirds means that each third of the image should fall within 45° or 90° from its neighbor. For example, if you’re shooting at f/2 then 90° would go from your subject to their right while 45° would lie in between them and behind their left shoulder. This is the idea behind the rule.

In order to follow it, make sure that when you’re focusing on your subject they are in the center of the frame or approaching its third. If you want a shallow depth of field, then place the subject in the third closest to you and push them farther into that zone.

In order to get this depth of field, you’ll need to adjust your aperture settings. Here are some examples: f/2 will give more than 4 times as much blur in focus as f/8, while f/1 will give you more than 10 times more blur and f/22 over 100 times more. To see a full list of the blur that different apertures will give you, check out this list on Wikipedia.

Taking these steps is also useful if your images aren’t sharp overall. When your photos are blurry, they don’t show the details on each of them, but instead seems to be all blobs. This could be because your photo was too close to something or that the camera lens didn’t pick up enough light.

If you think that this is the problem, you can check out the focal length of your lens and see if it is close to what would be a good focal length for you. If it’s odd, then you may want to get a different lens. There are advantages and disadvantages to each of them, so I recommend checking out our recommendation article for this section below.

Cheaper lenses are great but they have limitations and many people do not need these limitations. For example, if you’re shooting with a cheap wide angle zoom lens f/1 then it will be very hard to get an image that is straight because it has so much distortion. For this reason, it is better to pay more money on a lens and get one that is high quality, but that has a smaller range.

Each lens has an optimal focal length for each camera. For example, if you’re shooting with a 50” body then the ideal focal length for it would be around 24 mm. Most cameras in this category are now coming with an 18–55 mm zoom lens that’s considered “kit-lens” and they don’t have the sharpest of lenses. Some people prefer to get prime lenses instead of a kit-lens because they can achieve sharper images without so much distortion by getting single focal length lenses instead of using multiple ones.

We don’t always have to think about focal lengths, but in many cases we do. This involves the “portrait framing” process that we will discuss later in our recommended lenses article and it is a very important part of determining what lens to buy.

Autofocus (AF)

 

This is one of the most important things to look at on any lens. A good lens should have good autofocus speed and accuracy even if you don’t intend to use it for video photography.

The problem with cheaper lenses is that they can have very bad autofocus. It may take 10 seconds to focus when you want it to, or it may never lock on at all! Not only does this make your photography suffer, but it’s also very frustrating because you could be missing the shot while it tries to focus!

 

FREQUENTLY ASKED QUESTIONS

What’s a digital camera?

A digital camera is a device that records images digitally instead of on traditional film. It uses an electronic image sensor or charge-coupled device (CCD) to capture and store light reflected from the scene so it can be displayed as a photograph later. They use interchangeable lenses with zoom capabilities, allowing the photographer to use wide-angle or telephoto lens coverage while recording. There are also many different types of cameras to match your intended usage, such as sports cameras and surveillance video cams that fit into protective housings for outdoor adventures.

Is a digital camera any different than an analog camera?

Analog cameras take photographs by using a mechanical device, commonly known as a film gate, that exposes photosites on the photosite array of the light-sensitive element (plural photosites) inside the camera. The process of making a photograph is simply to place an actual physical object in front of or next to the light-sensitive element and expose it for a defined amount of time while some sort of mechanism for recording events is operating. Then we can make pictures on this device.

What can you do with a digital camera?

You can buy a digital camera to capture images easily with its compact size and have instant preview on LCD after taking photos due to its quick image processing speed. You can email your photos to friends and family directly from your camera without printing out pictures. You can also share pictures with others on the Internet – upload them using your camera’s ftp server or email.

How does the image get from the camera to my computer?

The image is saved onto a storage device (usually traditional optical film or flash memory) inside your digital camera. Then it is downloaded to the computer, where it is processed and compressed and written to a file on that computer’s hard drive. You can also view images in your camera’s “photo viewer” application before downloading and printing them.

 

FREQUENTLY ASKED QUESTIONS

What kind of storage media (flash drive, memory card, etc. ) does my digital camera use?

The most common form of storage is flash memory cards. They can be rewritten in any computer with a card reader, and are also used as portable storage media (i.e. transferring files between computers).

What are the advantages of taking digital photos?

Digital photos have significant advantages over their film counterparts. They allow greater control over exposure, color balance and sharpness compared to film cameras, once the picture is taken. They allow for higher megapixel counts (more than 35mm photographs) with significant quality increases, even up to 6 megapixel images with no noticeable loss of quality (compared to the roughly 2-3 MP resolution of 35mm slide film). Unlike film, pictures taken with digital cameras can be backed up and edited digitally later on, and therefore they can be changed without the need to physically change the original negative or slide.

What is a RAW file?

RAW, or “unprocessed” files are the unaltered original file created by the camera which contains all of the information that will be used to process images later. RAW files allow a developer to manipulate an image on a computer without loss of detail compared to their standard JPEG counterparts. RAW files do not contain any data on how the image is processed. It is up to the photographer’s choice as to how they wish to alter the file.

What is a captured photo?

Captured photo means those photos taken by digital devices that are stored in memory and later viewed in some way by the viewer that they have been captured by.
