i have a sony cybershot DSC-W7 . sometime when i make a group picture, i move farther away to capture all the person. eventually, the images of the people became smaller and sometimes unrecognizable.
Now, am thinking that i would try to buy a wide conversion lens, but i have no idea how the image would be look like it try to use it in a group picture.
Does the image became smaller as well if i use a wide conversion lens like the way i did going farther if i don't have wide lens? i mean the only difference is that, i don't go farther away from the image..
please advice.
thanks wide conversion lens also known as wide angle lens for other cam products There are a few problems with the wide angle lens option.
First and foremost, yes, the details (not the image itself, which would still be a 7 megapixel one, just covering a wider crop of the scene) would become smaller, pretty much the same as if you moved further away.
Second, it might not be as cheap as you possibly thought. Mind you, it's not just the lens itself (which, in the case of the one made by Sony, the VCL-DH0730, is listed as costing about 80$), it's also the conversion lens adapter, because you can't just stick the lens to the camera, there's no screw in it, so you first have to attach the adapter (which will cost you another 25$) to the camera, then the wide-angle lens to the adapter. There might be other wide angle lenses from different manufacturers, but you'll have to buy the conversion adapter anyway, and then make sure that those other wide lenses adapt to a 30 mm. screw. There might be little choice in the market, especially if you seek a minimum quality -and of course at a reasonable price.
Third, there'll be a certain loss of quality, particularly sharpness, compared to what you would obtain if the camera had the native wide focal length you want in a single lens group. It will be so even with the one made by Sony, but many third-party lenses, especially the cheaper ones, will probably be way too bad.
As Kevin said, your best option is to try and make a consecutive, panoramic shooting. That'll allow you to keep all the detail your camera can offer at a closer range, simply because the final panorama will be (almost) the sum of several, full-resolution pictures.
The problem could be that, unless you're shooting perfectly still objects, some of them might move between shots, and if they appear in more than one picture (that is, if they're in the overlapping zone between pictures), some -if not most- panorama programs might eighter get confused, or make a mess of the stitching. Fortunately, there are some advanced enough to take that possiblity into account, and help you correct the problem, either by simply compositing the pictures into separate layers (that you can then blend in Photoshop as you see fit), or by semi-automatically detecting movement changes in overlapping zones and allowing you to select which version/picture you want to keep for the composited panorama. One of such, which happens to be free, easy enough to use and quite effective, is Microsoft's GroupShot:
http://research.microsoft.com/projects/G... not sure what you mean by wide conversion lens.do you mean a screw on lens that go`s on the front of your cameras existing lens?if so you may have to put a small amount of optical zoom on your camera otherwise you will get round photos.all the lens will do is magnify the image.you will still have to move back to get everybody on.the name for a lens that allows you to get more on without moving back is a wide angle lens.hope this helps. The image will indeed get "smaller" if you use a wide angle lens, it is probably not worth it. A wide angel lens acts like the opposite of zoom, you can play around on your camera and zoom back, you will notice how the camera is seeing a lot "wider" and makes everything look smaller.
The mainly reason why professional photographers use a wide angle lens is to control perspective or if they don't have any more room to move back. For your needs, I don't think you should spend the extra money and get another lens.
If your camera has a panorama mode, you can take several pictures of the group and then the camera will stitch them together to make bigger image. |
