Digital cameras?

I'm not familiar with 'raster capability' in terms of photography, but it sounds like marketing to me for 'can use rasters'... which really shouldn't be anything special at all for a digital camera.

A 'raster' is a method of making a digital image by creating it pixel by pixel - if you zoom in, you can see pixels making it up. Another kind of method is called 'vector' in which the image is made by creating a series of points that are in continuous, smooth lines, all of them mathematically related to each other.

Digital photographs are best when they're created and stored in raster format, not converted to vector, because you can store a lot of detail in a raster, and you can get right down to pixel level to edit them one by one. Every JPEG, every BMP, every PNG, every GIF, and very TIFF and PSD you've ever seen have all been created and stored in raster format.

You'll see people talking about raster and vector in graphic design, and computer mapping (GIS).

Hope this helps a bit!

That helps a lot. The lovely mother of my children would always get the new and improved best-we-could-afford-on-a-tight-budget camera every time I would kill my work camera, her old one became mine. SO I was always a generation behind. She was (well still is she isn't dead or anything) a good photographer and a really good graphic designer. Once she went digital some of it started going over my head.

We are on decent terms but not on the sit-down-and-explain the stuff I at one time had little interest in sort of way.

Raster came up in that context. I was aware that some of the formats she used in graphic designed were in layers and allowed them to be manipulated independently... I thought it had something to do with that. Nice write-up btw.

That looks like a very good choice for my needs...

I kind of want a full sized camera with the ability to change lenses, but other than the vanity of trying to LOOK like I know what I am doing (which I don't) that probably is silly. With a 30x zoom, I cant see needing more than that and the wideangle looks more than adequate too.


darn I was sort of hoping I "Needed" a professional looking camera.

The image quality is good and I am very very picky. Did my own darkroom work, so my eye is somewhat trained

Want a REAL camera? Try the Pentax 645D. Yes, that's medium format digital. You want detailed photos? Ain't nothing better for the price. No, it is not a low price, but it's lower than the competition.

I'll put a word in for Nikon. You can pick up a second hand (good condition) D40 for pocket money.

Thanks. The layers would have been part of the post-processing of the image (correcting the size, colour, airbrushing, etc.), not something to do with the camera itself.
