Crop or resize? What happens when you pick a lower pixel count setting ...
To Crop or Not to Crop? That is the question...

Why is cropping frowned upon by some, and used heavily by others?
Crop good if you want extra zoom from chosen lens,
Crop bad if you want to keep wide angle from chosen lens,
Crop good if you want a bit extra zoom while retaining the arpeture setting of the lens as it would be set to wide.
To get this same crop effect, one would have to use an equivalently longer lens on a 35mm film camera.
Nothing changes about the lens; it's simply the amount of the image we use from the back of the lens.
Crop for Impact
Farmington Bay Waterfowl Management Area near Salt Lake City has ideal winter conditions, which often attract hundreds of bald eagles.
Crop - it's not seedy
Ask a farmer and a photographer what a good crop is, and you'll get two different answers.
One will say "wheat" and the other will ask "how long have you got?"! ...
The crop factor is something which is common with most digital SLR cameras these days as they use smaller sensors than much more expensive cameras.
The basics of the Crop Tool in Photoshop are fairly straightforward. After dragging a rectangle over your image, you press enter and the image is cropped as you specified.
Just remember the crop factor in your lens buying adventure. A wide-angle lens will behave like a normal lens when used on a camera with crop factor.
What if you don't crop? Well, you have different views, but you can still compare DOF I guess. The focal length of the lens is the same in each case, so the ratio of the DOFs is just the ratio of the circle of confusion values, 18.
Techniques Glossary CROP FACTOR
Describes how much an imaging sensor has been cropped in relation to its full-frame equivalent. It always describes how many times larger the full-frame is in relation to the cropped sensor.
CROP FACTOR SENSORS AND LENS PERFORMANCE
The crop factor, FOV and perspective rules follow each camera through it's entire range of photographic capabilities from wide angle to telephoto. If you want the equivalent of 24mm on a 1.
CROP FACTOR & FOCAL LENGTH MULTIPLIER
The crop factor is the sensor's diagonal size compared to a full-frame 35 mm sensor.
Crop. To trim the edges of an image, often to improve the composition. Cropping can be done by moving the camera position while viewing a scene, or by trimming the finished print.
We're going to start by cropping the photo so that it has a horizontal orientation.
Crop or retouch
As visual communicators, we're responsible for everything that's in the frame; we're also responsible for everything that's not in the frame. Read More...
Crop the image to the desired aspect ratio. Programs such as Photoshop let you crop or select areas of an image using any aspect ratio that you specify. To do it manually you:
1. Determine the aspect ratio you want to use.
Crop. To use only a part of a photographic image by cutting out the portion not wanted.
Daylight. Sunlight that is either direct, as on a clear day, or diffused through clouds on an overcast day.
The action of trimming away the unwanted parts of an image.

CROP FACTOR - A number used to multiply a lens's actual focal length to express how much of an apparent increase you can expect in the effective focal length of any traditional 35mm SLR lens you use on a dSLR camera.
In computer graphics, to cut off the sides of an image to make it the proper size or to remove unwanted parts. Most graphics applications allow you to crop images with a clip feature.
Crop Factor ( or Lens Crop Factor): Digital cameras typically have sensors of size less than “full-frame' (24 X 36 mm).
Crop. To trim an image or page by adjusting its boundaries.
Cropping. Cutting out unwanted (edge) parts of a picture, typically at the printing or mounting stage.printer or monitor when compared with the original image.
- Generally considered better for macro, especially for super-macro
- Approximately 60% more depth of field than a full-frame sensor, given an equivalent field of view ...
to opaque, mask, or trim part of an image to fit a designated area.
sometimes referred to as tick marks, small marks placed in the margin, denoting the live area or areas of an image to be reproduced.
Crop your photograph. You probably have a lot of unnecessary empty areas in your photo (and probably some of the background behind the white paper, too).
3 Crop And Rotate. I'm a strong believer in cropping out problems early on. Junk often shows up along the image edges, for example, and it's worth removing that junk and fixing crooked horizons before moving on.
5. Crop in the right places. When taking pictures of people, the bottom of the frame should be across the shoulders, hips, middle thigh or middle calf. Making people look like a head only or an amputee is not flattering.
In 3D mode you get the same limited exposure controls as before, but the camera will only allow you to pan left-right (or vice versa).
DO I CROP OR USE A TELECONVERTER?
Cropping into an image gives the same effect as using a longer lens. To check whether this is a practical option we did a test using a Canon EOS 5D, with a 100-400mm lens set to 300mm and the 1.
Use this option for automatically trimming the output image to avoid artifacts on the edges.

Don't crop just yet!
If you recall from earlier on, chromatic aberration is more prevalent on corners.
Rotate, crop and matte photos. Photo editing software makes it simple to rotate a photo (90 degrees if you took the picture with the camera turned to the side, or smaller amounts if the horizon is just slightly out of line).
Step 1: Crop Out Distractions
Have you ever looked around you and been disappointed about your subject's location? Maybe it's a messy home interior or an unremarkable backyard.

I had understood that you had to calculate this with the crop factor included so the 50mm lens would need a shutter speed of 1/80 or higher. Your article seems to contradict this. Which is correct?

Panoramic Formats: Panoramic formats have become very popular in the past few years. Many 35mm cameras now include a panoramic inserts as well as some range finder and medium format cameras.
Focal Length Multiplier and Crop Factor
Whether a camera lens is seen as wide-angle or tele is dependent on its Angle of View (AoV); for a particular image size AoV is dependent on focal length.
Use to crop during printing. edge number Film has a clear unexposed strip running the length of both edges.
A high MegaPixel count comes in handy when you want to crop pictures, and when you want to make enlargements. For uncropped 4x6 prints, 2 megapixels are usually enough, but for 5x7s and 8x6s, you kinda need to go up to 3 if you want a sharp picture.
Smaller sensor also has a "crop factor multiplier" because it has a smaller surface than a 35mm camera film, it takes a small portion of the projected image (crops the image) and produces a normal frame, ...
Most also include image-editing software--which lets you crop, adjust, or add special effects to your photos--and the cables and/or cards you need to connect to your computer.
3x 'crop factor' provided a good compromise between effective magnification and image quality. Its replacement, the 1D Mk III, was an improvement in most respects, but was plagued by autofocus problems.
If you have to crop, you can do that later on.
Avoid filling the frame with your subject's face. Sometimes, if you don't make use of a leveling device like a tripod, your photo may not be straight.
In DSLR cameras it is important to know about the crop factor. Since the sensor in the cameras is smaller than a 35 mm film frame you need to consider the crop factor. In cameras using the APS-C sensor this factor is 1.5x or 1.6x.
Step 3: Rotate and Crop
If you've taken a photo in a wrong orientation, it's easily corrected with little loss in quality by using a rotate tool.
A subject is framed if the photographer is able to include and crop surrounding objects so that the resulting lines and shapes lead to the subject.
In CS3 I enjoyed using the crop tool to slice although I'm sure Adobe intended the slice tool to be used. In CS5 the crop tool has become the Artboard tool which takes a bit to get used to.
Photo pro's will then use Photoshop or other image editing software to crop the image more tightly into the bolt. If the bolt is primarily vertical, cropping will follow this orientation.
Granted, it is easy enough to crop away unwanted areas after the fact and thereby make them look like they were well composed in the first place, but unless you have a high-megapixel camera and have remembered to shoot at high resolution, ...
The idea is to crop with the viewfinder, or in the camera, not in the darkroom. Think of it this way: a 35mm negative is roughly 1 × 1½ inches. To get an 8 × 10 inch print, you need to enlarge that negative by some 533%.
