A picture is a great way to put a message into motion. You can create an everlasting impression with your photos, so why not give yourself a gift and try photoshopping them?
You can go for some unusual angles, transition effects, or exciting backgrounds. Whatever you choose, the key is to put some effort into it.
The best way to edit pictures is by using a camera app on your phone or computer.
Calculate the new image distance
When you shoot a photograph, your camera measures the distance between the lens and the subject. The closer the lens is to the object, the farther the image will be.
To calculate this new image distance, you first have to know your focal length and then your magnification. Your magnification can be found in your camera settings, in Figure 1-1.
Figure 1-1: Settings for a Canon 5d Mark II camera.
Canon has two settings for magnification: full frame or smaller format. When you have a larger format camera, like a Canon 7d, you can set it to full frame mode to get a longer image length!
When you turn on your 5d Mark II, there is a setting for how big an image you can take with its sensor. If it has an 8-16x zoom on it, then it has an actual size sensor! You must call out this feature before buying so that you can get this extra length out of your pictures.
Calculate the new image size
Now that you have your new lens size, you need to calculate the new image size. The formula is:
new image size = focal length × lens width / distancescan.
So, if your new lens has a focal length of 12 cm, then your width of the image would be half that amount (6 cm). If you wanted a larger image, then increase the height of the frame or decrease the diameter of the lens.
Saving Mode: You can also calculate the new saved image mode using the same method. Just make sure to include “saved in” in there!
Text-only display: If you have a text-only display, than your new mode would be “text only”. Having a “display” mode will save some memory on your device.
Determine if objects are magnified or reduced
If you can see anything beyond the 30 cm width of the object, it may be because of a lens that is wider than a normal lens, or a converter that changes the size of the lens.
If you can see any change in size when the light changes, it may be because of a photoshot.
If you can still see an outline or shape even when the light is very bright, it may be because of an inflight flash.
If you can still see details even with very weak light, it may be due to an incandescent lamp or flashlight.
Any light source that produces shadows will cause lose detail in objects and decrease in brightness on camera.
Understand that objects closer to the lens are bigger but smaller in size
When shooting close-up, remember that the bigger the object, the bigger it may appear. This is due to the curvature of the lens.
The sharper the lens, the more exaggerated the corner sharpness will be. Since a smaller object will appear smaller in your image, this will also apply to your depth of field.
Since longer focal lengths require more money spent on equipment, it is important to budget for them. Some people may not have enough money for a decent DSLR and zoom lenses but can still shoot close-up with less money.
Start off with a small kit so you get your feet wet and then move up from there! You can always buy yourself a new set of gear to match your current skills.
Know that objects farther from the lens are smaller but bigger in size
When looking at photos of people, you might notice that they are smaller in size than you. This is because people use a Focal Length to represent their size.
As the lens gets longer, the person is larger. Long lenses look bigger than short ones due to this phenomenon.
When shopping for lenses, try to find those with short focal lengths so that you do not appear larger than your subjects. However, if you find that a longer lens looks better on your face, then go with it!
You can also try looking for lenses that are 30 Cm (10 ml) in front of the camera to see if they make you look bigger or less big.
Know that parallel lines remain parallel after passing through a converging lens
Most lenses have a tolerance of an object’s height or thickness that the lens can accept as a reference point. When a lens is passed through a converging lens, it must accept the thickness of the object as a reference point to be parallel to the lens.
This tolerance is applied when passing through a nonmetric convergetal lens, such as an évaluative or unifocal. When a convergetional lens is used, such as a normal or normal zoom, the thickness of the object must be accepted as a reference point!
When buying lenses, it is important to know this tolerance so that no two lenses will have exactly the same shape and size on the outside.
Understand that a converging lens reduces an object’s height and width but magnifies its length
A converging lens doesn’t reduce an object’s height or width. It instead reduces the object’s thickness, increases its width, and decreases its height.
This happens because a converging lens has a thinner film inside it that contains the photosleepership.
A converging lens has a focal length that varies based on the camera brand and model. Some have shorter focal lengths than others. When you use a longer convergent lens on a camera with a shorter focal length, the thickness of the lens is reduced – even though it may look same – when you use a shorter convergent lens on an identical sized camera with a longer focal length.
This happens because of metallography, which determines how thick objects are in relation to their diameter.
Recognize that a diverging lens magnifies an object’s height and width but reduces its length
A diverging lens can be very helpful if you’re shooting a tall or large object. It can make the object look thinner and more streamlined, reducing the likelihood that you’ll notice an absence of detail in the object.
But the sameLens can be disadvantageous if it increases the length of an item such as your wetsuit. A longer wetsuit will generally take longer to dry, making it more likely that it will wet yourself while diving.
Determining whether a lens is a diverging or converging one can be tricky. Most lenses are considered diverging lenses because they have a stronger diopter correction requirement.
However, many people find that converging ones are better for taking photos of larger items as they are because of their shorter length.
