how to make diff resolution on Digital Rebel

[StevePhelps 0]

The images on my didgital rebel are saved a JPGs about 40 inches wide and at 72 DPI. Is there a way to have them smaller like 11 X 14 with 300 DPI?

What quality do you have it set at now? Look on pg 48-49 for the description of your choices or IOW....RTFM

steve,

I believe you have the camera set to large, correct?

From what you said 40 inches wide at 72 dpi makes sense. You are ok. The image size 42 inches wide at 72 dpi is the same 11X17 at 180 dpi for 6mega pixel images.

Go into "image size" in photoshop. ( I assume you are using it.) And change the print size to what ever you need with out resampling the image. Make sure its not selected in the dialog box.

There are a few ways to do this but learning how the image size dialog box works and the difference between print size and pixel demesion is important.

Peter:

Yes, it is set on large. So the only way to change is with software, not the camera?

[blazetailman 0]

well yeah,

The size in raw pixel is the same. The print size is what we are changing. Just make sure the resample is not selected and constrain proportions is checked.

I am assuming your wanting to do this for several photos ie: tandem customers? If you use PS I believe you can batch convert your photos to your parameters with a few easy clicks. You should of gotten a PS elements CD with your camera and I believe that has a batch convert option on it.

I may be dumb, sorry -- really, I'm educated (Master's degree) but very kinestetic. I learn by seeing & doing, rarely by simply reading.

I set the image as large and used the canon utility to transfer (download) I set it's perameters as 300 DPI, but what I get is 72 DPI. (42 inches long)

So, are you saying, Peter, to use PS to change the DPI from 72 to 300? I did this while changing the size from 42" to 11" and it "seemed" to look okay, but I haven't printed it.

I know what you mean. That's why they always put pictures in the FMs and on the Claymore bag

I'm at home now and I checked PS Elements, which you should of gotten with your camera, and it has a way for you to batch process your pics and set the image size and dpi. See attached picture. Is this what you're trying to do?

Yeah, thanks, that helps.

Wait guys.... slow down a bit. here.

Steve what is the reason you need to convert them.

Beacuse we are only changing the specifications on the "print" size and not altering the image at all.

1) magazines require a higher DPI

2) wouldn't a higher DPI "look" better as a print?

[blazetailman 0]

ok,

Changing the print specs only effects the printing of the image. So if you send the file to me for example, It is the same high quality image as it would be if we send it to the mages.

This might be tough to explain:

Raw pixels in image demsions is true scale of resolution. So for example ...

there is no need to batch process them. if you are sending the digital images out to magazines, then send the jpg. as is. that is the untouched file.

If you start messing with the print resloution, I'm more worried that you will end up upsizeing the image or shrinking it degrading the quality.

I hope this is starting to make sense. I realize I am not a writer. That's why I'm a photographer.

so if there are more questions, I see when I can reply but packing up for the nationals.

I agree with Pete. If they are for the magazines then you want to give them the best possible image to work with. I thought you were trying to find a way to process shots for tandem clients.

All digital cameras record their image at 72 dp1. The only difference in camera to camera is the image size. Mine shoots 34x40 at 72 dpi. Other cameras are bigger or smaller.

You resize in editing software. I use photoshop and normall don't resize. The lab I use ( I am a professional Photographer) doesn't want it resized. The interpolation software on their printers is better than photoshop.

On digital cameras the main thing you can change is the size of the recorded image and the amount of compression of the image before it is recorded on the flash card.

You want the largest image you can get. if you need quicker shooting speed, the increase the compression. Raw takes the longest to record, and most cameras have 3-5 different jpeg compressions.

The compression will make the recorded image smaller thus making the transfers faster.

Hope this helps.

Very helpful, thanks! One last follow up question: When Parachututist requests the image to be 300 DPI, do I change it with PS or just send it as is?

[ffp1974 0]

resize it in photo shop.
