I need to get magazine quality pics from this camera. Is it possible??

The editor has told me "photos need to be 300dpi and 213mm wide and 303mm deep please"

At the moment I am producing 180 dpi. :confused: (considering Im not sure what dpi actually means, it's a bit tricky to sort out. LOL)

I also have Photoshop cs which I usually use to resize etc etc.

Is there anyone out there who can help me out. What do I need to check to get this right?

Thanks. :kiss:
 
DPI stands for Dots Per Inch. Usually I hear that in relation to the output resolution of a printer. Cameras usually are measured in Megapixles. You'rs is a 3.2 Megapixle camera, which is decent for snapshot size pictures. I'm not sure of any correlation between DPI and megapixles. Are they asking you to print pictures or can they accept an electronic image?
 
They are accepting electronic images. but I am having such a hard time getting it just right. I don't want to give up yet, though.
 
Your Canon A70 is a 3.2 megapixel cmaera. I think it has enough resolution to handle this request. The desired image size is tiny.

Go to your HELP MENU and select RESIZE IMAGE.

On the First Box select PRINT

On the next box select your size for the image. You will need to use centimeters and convert your millimeters to a centimeter unit. For example 303 mm deep would be 3.03 cm. Note that it will give you no choice about the other dimension. This will have to be taken care of later.

In the subsequent box Select OTHER and type in 300 lpi (you might actually ask how many lines per inch the print for their output.)

The next box is a slider for image quality. Play around with that. If you don't have enough data to fulfill the request, it will let you know.

The problem here is that in printing dpi (dots per inch), pixels per inch and lines per inch are sometimes and erroneously interchanged. They really are somewhat different things.

After you get your resized image, you can adjust the dimensions so that they are precisely what they asked for by cropping the excess.

Hope that helps.
 
as I remember dpi is a printer measure. dot per inches.
while megapixel is a screan measure. They is no link between the too.
My guess is to take the best quality shot with the camera and edited them with photoshop using the best quality to save them.

Disclamer I know nothing about pc only mainframes

I would think the best thing to do would be to take the best pictures you can at your cameras highest resolution. That should do it. Or, let them worry about the technical stuff.
 
213 millimeters = 8.38582677 inches along side 1
303 millimeters = 11.9291339 inches along side 2

8.3... inches * 300 dots per inch = 2515.74803 dots along side 1
11... inches * 300 dots per inch = 3578.74017 dots along side 2

2515... dots * 3578... dots = 9003208.53 dots total in the rectangle

which is 9.0 megapixels, a long way up from 3.2 megapixels

(dot is another name for pixel)
 
Thanks for the tips.

Looks like I'm going to be fiddling all day..................LOL
 
The A70 can't take an image that large at that res. At 2048x1536 pixels and 300dpi, You wind up with an image thats roughly 6.5 x 5" I think (sorry, lil rusty on metric sys).

Ask the publisher what Lpi the magazine prints at. They always tell you you need to make images double the resolution of whatever line screen they use to print, but the reality is that you can get away with 1.5 times a lot of the time without anybody knowing the difference. That might get you enough wiggling room to make it work.

Well--I was only one order of magnitude off--lol.

Now looking at my references, A high quality annual report is printed at 175 lpi,

Nonetheless--you can't do it. Period. I can't do it with a 5 megapixel camera.

you need 16 megapixels to equal film

right now we can do about 10 or so very expensively

to meet the spec you suggest I don't know without research but

4-5 megapixels might do it

4 megapixel cams are now affordable

goto cnet.com and enter canon A70 in the search box to see the reveiw of your camera

i imagine it's a 3 megapixel )MP)

or 3.1

that may not be magazine quality but it's not too far under it

I don't think it's possible directly from the camera, but in conjunction with a good photo editor's resample function -- Adobe PhotoShop would be a good choice because you can set the parameters given directly -- you should be able to produce acceptable pictures for submission.

ClaudiusMaximus got the Math right -- the target size is 2516 x 3579 Pixels if you're using an image editor like Irfanview or PaintShop Pro that resizes based on Pixels instead of DPI and Paper Size.

Did the Editor also give you preferred file format? -- JPeg is a "lossy" format and will distort the image if you set the compression to high when you save; If you use JPeG fomat set it to maximum quality and preserve the original file just in case. BMP Format is a lossless format, but it produces HUGE files at that resolution (about 206 MB in 24 bit "True Color") I'm not familiar enough with other formats to know which are "lossless" formats that support "True Color" (24 Bit) or "High Color" (16 Bit).
