Digital Photography help.?

I am a complete Idiot when it comes to digital pictures.

I have a photo which I wish to have done into a canvas print.

The photo was taken on a 4 mega-pixel camera.

I have been onto the tesco web site, which allows me to do a canvas print in a 40cm X 40cm size, but I would like it bigger.

But when I try and make it to a 60 X 60 cm size it tells me that the resolution of the picture is to small.

What I need to know is, Is there any way I can resolve this issue, by doing any adjustments to the picture or anything else.

I would really appreciate any help or advice.

the picture wont be good big because you took it with a 4 mega pixel camera. your best bet is see if your friends have a 8 or 10 mega pixel camera you can borrow. the More mega pixels the bigger you can blow up the picture x

it should be under the settings.

what camara do you have

Basically, it means at a bigger print the picture will lose a lot of quality. However, all is not lost. Go to a professional printer in town, they will do it for you.

they should be some thing as ya can put ya photos through your tv and there real clear and huge

Unfortunately if you blow up the picture to larger specifications you will begin to lose resolution and the image will start to look pixilated. There isn't really anything you can do about this. Sometimes even if the image is pixilated however, from a distance it might look ok depending on the image.

you cannot increase the resolution if you've already taken the photo.. you can take another photo after changing the setting on your camera to a higher resolution then try again.. you should be able to go upto 1600 x 1200 resolution with a superfine quality, then you can have it blown up poster size if you wanted

An easy way to increase your picture size (but the quality won't improve) is to

(1) open Microsoft paint program (i.e. mspaint)
(2) drag the picture into the paint program
(3) Under image, select stretch/skew option.
(4) Enter new horizontal scaling, and vertical scaling numbers (eg. 150%, 150%). Your picture has just increased by 225%.
(5) Save the new picture as a different file name. You'll notice that the file size is much bigger.
(6) Try this picture in your canvas tool.

Note: The quality of the picture will not improve since no additional information is gained or generated by making the picture larger. It will still contain only 4 mega-pixels of information.

It is only 50% bigger. There isn't any reason why you cant Rez the picture up. Yes there will be a small drop in quality but there is a drop when you go the the canvas anyhow.

Just find someone with photoshop.
If you tell them to Rez it up using Bi Cubic smoother you will be fine.

As in my knowledge and experience, try to scan the small photo into a bigger size image in computer.

4MP, normally is some point&shot camera, which only product a 180DPI max. Means, even you're printing 40x40cm the colour won't be that good enough, not to mention 60x60cm..

Here's an idea for you. I just had a canvas done from a slightly soft image, but one that I just loved. I ran it through Adobe Photoshop and put a watercolor filter on it (very weak amount of effect, I didn't want it to look like a paint-by-number) Then had it printed as a 16x24 on canvas, and it looks fantastic. Now, this method won't work on every print, but mine was an outdoor scene that was actually enhanced by the loss of a bit of detail. I am including a link to the photo I'm talking about. Maybe it would work for you, too.

Having it done as a canvas will mask some of the pixelization, but it might not be enough.

Photoshop can interpolate an image larger (or smaller for that matter).

Go to Image>Size and check the Resample Image box and then from the drop down menu select Bucubic from the choices there. Alter the size of the shortest dimension to 60cm. Don't expect too much from a Jpeg though.

Now for the professional approach.

In Photoshop select New. In the dialog box select the print size you want in inches (you'll see why in a moment, 60cm is 23.622 inches) then alter the resolution value till you get a filesize of 1Mb per inch on the longest edge. This will be around 122 or so, a file size of 23.8M, close enough.

Now for the clever bit, go into Bridge and highlight the picture you want, then File>Place>In Photoshop. Photoshop will open your New file and place the picture in a new layer with a bounding box around it already to go. Hold down the Shift Key (to keep the aspect ratio) and drag the corners out to fill your New canvas, and when happy press Enter, or click the green tick at the top of the screen.

It's unlikely the aspect ratio of your pic will match the canvas so select the Move Tool and you will find that you can move your pic around on the canvas and you can select which part of the pic you want to print.

At this stage you can apply sharpening, Levels or Curves etc..

Double click the Zoom Tool (Magnifying Glass) this will let you view your pic at 100% and you can see exactly how it will print.

Flatten the image save as preferably Tiff if your printer allows this (Tesco probably won't and you may need to save as Jpeg). This file will print 'natively' at 60 X 60 cm.or any other size you make your new canvas. The trick is the 1Meg filesize per 1 Inch on the longest edge, this technique offers the maximum resolution to fit the output size required and will always print really well.

What we have done is force Photoshop to re-scan the image to the new size, you'll be surprised at how far you can push this, but obviously there are limits.
