I am trying to export some images to my desktop to then pass on for inclusion in social media or a website.

Please can someone offer some assistance as to what settings I need to choose for File Settings and Image Sizing?

Thanks.

Web color space is sRGB, quality for web is 70 or greater. Generally will not see different above 70. Resolution for web is 72 pixels per inch. Long side dimensions really depends on how large you want images to appear and also depends on screen of viewing computer. I would suggest 1500 to 2000 pixels.

Can you recommend a link to some pithy definitions for me?

I’m struggling even with the basics. Why is a ‘long edge’ relevant?

I’ve really only known that my jpeg images were about 1 mb and now that I’m shooting raw my images are around 10 mb. As for the resolution, number of pixels etc … I don’t understand the relationship to the mb?

No one can answer that as it depends on what size and quality you want your exported photos to be.

If I’ve not exported photos before, how am I supposed to know.

The images are for social media and to go on a website. What settings would you recommend given that I don’t understand resolution, ppi, …

Per, I’m so grateful for the links to your very well written articles. Your explanations are brilliant although I’m going to have to read them a number of times before I am able to fully absorb the content.

There are a few nuggets of information though that have already provided light-bulb moments for me!

Needless to say though, I have a couple of questions:

For on-screen viewing, ppi is irrelevant. If you post an image on the web, it will display exactly the same regardless of what the ppt is set to.

I struggle to understand how an image with many more pixels will not display any better than an image with very few pixels??

ppi - this is chosen according to quality of print you require?

The image above measures 300 x 450 pixels.* To print this image, the printer driver will divide the pixel dimensions by the ppi value to calculate the printed dimensions. Let's say the ppi is set to 300.

300:300 = 1 - and 450:300 = 1.5 - so the print will be 1 x 1.5 inches, or roughly 2.5 x 3.75 cm.

If the ppt is set to a lower value, it will print bigger, and if set to a higher value, it will print smaller.

what determines the pixel dimensions of an image?

your camera?

the type of file raw/jpeg

Thanks so much for your support.

Here's a very good article on the correlation between Resolution, PPI, and Size (in/cm) inside the Export module:
