How does the camera deliver the 2x digital zoom pictures? Cropped or interpolated? (I know digital zoom is almost useless, but I am curious)

All digital zoom does it crop and zoom and image. No interpolation.

Is it possible to use digital zoom and shoot photos in manual mode?


Although your EOS 600D does not support digital zoom, while shooting, the same effect can be reached when the picture is already on the memory card. If you want to zoom in later (Crop) please shoot in RAW (or RAW + JPG) Only then all details will be preserved. Later you then can crop the part you wanted to have in the first place. I know your camera can crop the pictures you want to print from the camera. I'm not sure you also can edit RAW pictures and later save them (cropped) as a jpg.

What is the difference in the optical and digital zoom?


Hi,

Find the difference below

Digital Zoom

1. Digital zoom is a part of digital cameras, and camcorders, which helps to crop the entire image, and then digitally enlarge the size of the viewfinder of the portion that is needed to zoom in on
2. Digital zoom crops the image down to a centred area with the same ratio as the original, and also interpolating the result back up to the pixel dimensions of the original. this method involves cropping, hence the resolution and quality is reduced
3. Digital zoom, crops a portion of the image and then enlarges it back to size. And due to this, image quality is reduced in comparison with the original one.
4. Using the digital zoom allows the user to get closer to the subject when the photographer wants to be discreet about taking pictures, like taking a picture of a person in a graduation ceremony.

Optical Zoom

1. While taking a picture using a Camera to want to get a close shot of the subject without moving physically closer, photographers use the optical zoom.
2. The optical zoom ratio of a digital camera measures how much the lens can actually zoom in to make subjects appear closer. Optical zoom, enlarges a picture while keeping the resolution and sharpness of the picture high.

3. There is no relation between optical zoom and the resolution of the photo, as optical zoom only enlarges the whole image or the subject to a certain range. So image quality only depends upon the mega pixel (MP) of the camera

4. Optical zoom is very useful, while taking a picture of a landscape, or to get a closer view of a subject, without reducing the quality of the entire image, like taking a picture of a Rainbow in the sky.

I DON'T HAVE A PROBLEM; i'M JUST LOOKING FOR INFORMATION/OPINIONS ON THE COBRA DCA1650 DIGITAL 16MP 8X ZOOM CAMERA.


Think you'll be very disappointed in image quality and just overall quality of the camera. And I'm pretty sure that 16MP will be interpolated 16MP, and that 8x zoom will include some digital zoom enhancement, neither of which are desirable. If you're looking for a good quality low cost camera that will take great pictures, consider this, or this, or this.

Turn on auto focus and when you are taking a shot let Auto-Focus adjust the blurry image in the viewfinder beforeyou take a shot. If you do not know how to do it please let me know and I will give you detailed instructions.

I want to save picture that we took in a zoomed in mode -magnified larger than it was originally taken? is this possible?


You can do that in a photo-editing program. It's called "cropping". You select the area you want and the rest is cropped out.

Hi there I just bought a eos d2000 camera and am concerned about the file size when transfering the images onto my laptop. they seem to be way smaller than most digital images and im not shure if this is a...


Go into the camera's settings and see if there is an option there to change the resolution, if it's the size in MegaPixels you're concerned about.
There may also be an option to take the pictures in RAW format rather than JPG, if it's the size in MegaBytes that you're concerned about.

Other tell-tale signs of small files could be:
File is a video file.
Picture was taken as a burst or panoramic.
Digital zoom was at full. (Try setting the camera to not use digital zoom - it's basically just cropped.)

RED DOT


Hi,

If the dot is not visible in print, but only on the camera's screen, the its only the LCD that is faulty.

If the dot is visible on screens and in print, then yes, it could be the sensor. Try taking pictures without the digital zoom. Chances are the dot is only visible with the digital zoom because the picture is interpolated.

If all else fails, you can try cloning out the spot in an image editor on the computer.

Optical vs. digital zoom


It's important to understand this difference, as you could be disappointed with the results if you use one rather than the other. Optical zoom works like the zoom on a traditional film camera. When you push the button to zoom in or out, physical lens elements move inside the camera, reducing the field of view and making the object you're shooting appear closer. Digital zoom, on the other hand, has no moving parts. The camera interpolates a small portion of an image to artificially restore the file to its original size. Using its electronic brain, the digital camera analyzes what it sees and digitally zooms in, usually two or three times closer. Unfortunately, digital zoom also reduces the resolution of an image, so your picture will tend to be more pixilated than the same image taken with an optical zoom camera. If you're just snapping an image to e-mail to a friend, this loss of resolution won't be so noticeable. But in situations where the highest quality counts, skip the digital zoom and use your PC's image-editing tools to zero in on your subject.
