image size question

thebaz

I was going to enter a photo in the Late Late comp, then i noticed that most of the images from my Nikon d50 , won't satisfy requirement.
I don't shoot raw , and use image size L , 3008 x 2000 , and quality JPEG norm , 1:8 .

This all seamed fine until , i brought the dpi down from 300 to 72 , and the min size is well below 1,000 -- is there something wrong with my setting on Camera ? should i use a higher res ?

sorry for a stupid sunday morning question, but i think something aint right !

hi, if you want to decrease dpi from 300 to 72 don't resample image! It will preserve the original pixel size of the image.

Hope you you'll make it OK now.

good idea, some of those B&W Dublin shots should have a good chance and the 10k prize could be used as a springboard for your exhibition

I'm wondering do you guys always use the best quality setting on your camera, or do you take it down a few steps, if so to what?

I've just bought a 400D but before that I was always using canon Ixus compact cameras. Although my current one is 6MP - I only ever use it at about half it's actual capability for quality - dimensions of 1600x1200, which is fine for me.

However now with a 10mb camera capable of images up to 3888x2592 and also the capability of RAW. But Am I correct in saying you only need these big sizes if you want to print huge photos?

The other thing to think about is if you shoot at max size and want to upload any photos to the web or send to friends etc, you will probably have to resize, which is a pain. At least at 1600x1200 it's big must not massive, and will still print at a decent size.

What settings do you use?

Huge sizes are handy for cropping too (or you could just get composition right during the shot )

I normally use the 3 megapixel fine jpeg on my dSLR unless I'm doing a "proper" shoot - then it's either 6 megapixel jpeg fine or raw.

I can't remember what the photoshop dpi settings are like, but you should be able to change the dpi without changing the pixel count

I know in irfanview changing the dpi, doesn't have any effect on pixels or do any resize. If printing at 1:1 the dpi will determine the size of the photo on the paper

ok , figured it out , just had to deselect "Resample size" in "image size"

Hope my camera image setting are ok anyway

I was just about to say that!

Ttomasso already pointed that out

Don't forget to trim the image size down to 3000x1995!

You wouldn't want to be disqualified for posting above the maximum limit

I'd recommend you shoot at the max all the time. It only takes 10 seconds to resize and you cam automate it very easily if you want to do a batch. I only shoot RAW now because if I am ever lucky enough a really good shot I know that I can print it big, enter it in competitions etc.

If you restrict yourself with small images the day will come when you will regret it, guaranteed! 1600x1200 is really small by today's standards and way too small if you win something and need to produce a Hi-Res image or if you want to a large print of a special shot.

You can set up a workflow that will make life easy and where you can seperate the good ones.

sure were all freinds here

anyway the only requirement regarding size i saw was

Minimum size of 1500 pixels on the longest edge at 72 dpi
Maximum size of 3000 pixels pixels on the longest edge at 72 dpi

Thirdfox

...just in case you left it at 3008 pixels on the width

They might be stingy about those 8 pixels

maybe its cropping or due to b/w conversion, but most of my images are usually a lot smaller than the 3008 x 2000 setting on camera --

Thirdfox

B/W conversion shouldn't affect the image size but any cropping at all would take you past 8 pixels.

Now I have to find a place to upload the 4/5 mb photos to my email account and send it off to halifax (my broadband is only 1mbit - so slow on the upload!)

another one for any camera techies -- i currently have my camera set to Medium size (ratio 1:8) -- would i be better to up it to the Fine setting (1:4) ... i assume my storage will double , is it worthwhile ??

cheers

Always use the "best" settings Barry. Especially if you ever want to print at a decent size like for an exhibition. It's then you'll regret not having done it.

Roen

For the type of stuff you do you really have to have the camera at it's max setting. If it does raw then go for that. Failing that then max jpeg.

You tend to shoot people, and they are unpredictable as hell. There's no time at all between the best shot ever and the worst shot ever when you're off doing the whole documentary stuff.
So leave it on max and when you capture a gem you know you'll be able to print it up well.
And as for storage. it's free if you know where to look.

thebaz

cheers guys

Barry if you want to exhibit you're gonna need large prints. A decent storage card is pennies these days. Best and biggest format all the way!
