How to increase the size of some photos?

dinneenp

Hi,
I have some photos that Getty requested to be added to their database (through Flickr).
However the photos aren't the minimum 4MB, close but not there. I've heard some rumors that you can increase the size in Photoshop, Lightroom or similar programs? Is this possible? I presume it'd reduce quality but at least I could then submit them.

Cheers in advance,
Pa.

You can increase the image size in photoshop. Your simply increasing the size without adding any more pixels into the image. You can do it in one big step but it is recommended you do whats is known as "stair" or "step" upsizing by increasing its pixel size by about 10% each time as this is meant to help keep the loss in image quality down more than doing it in one big jump.

its under IMAGE>IMAGE SIZE and it should be all there.

try just resizing it by 200% and saving it (as new name) and see what it gives you. If that doesn't work then try 300%. Trial and Error.

if using the gimp you'll find it under image->scale image

You are correct - it won't be doing anything to improve the quality. If anything it will detract i'd imagine - how much so depends on the software you are using and its approach to upscaling an image. I'd expect that it would be ok to use - certainly in the absence of anything else.

A lot of pro's don't consider this method valid within Photoshop anymore. The new algorithms since version 7 have actually done this within the upsizing algrorithm.

Some people still insist on using Genuine Fractals to do upsizing as well. (personally I think it works well on some things, but not on others.)

If you you have Photoshop....

1.Open your Raw files or your Jpeg in Raw converter. You may have to change some settings to let your Raw converter open jpegs... but it will do it.

2. At the very bottom of the raw convert screen, you will see your image information, resolution, mega pixel information.

3. Click on this and then select the size you want. The max you can up scale to is 25mp. It works best on Raw files. I am able to make decent 25MP jpegs from my 6MP Nikon D40.

Give it a try.

That method hasn't really been necessary since Photoshop 7. The upsizing algorithms were changed to do this automatically. (Might have been version 8/CS1)

It's possible to increase the pixel dimensions of images in several ways - some of which are described above - but I doubt that Getty would be pleased that you're trying to "cheat" your images up to the minimum specifications. From your original post, you say that the minimum requirement is "4MB". This is not a spatial measurement, it's a measurement of file size. You don't necessarily have to increase pixel dimensions to increase file size, and it might actually be a fairly inefficient way of doing so. How were the JPEGs on Flickr created? You must have processed them somehow from a larger file unless you chose the lowest possible JPEG output from your camera. I suggest you use the original files from the camera to create a good file that's greater than 4MB in size as opposed to padding out your existing images to cheat your way into Getty.

If you have the RAW file then there is an option in CR which will allow you to set the size of the image you want to edit in PS. It is at the base of my CR window. Pull down the menu and select the size, but remember to put it back afterwards as it remembers the last setting. It does interpolation very well.
