Obtaining Tweeted Images in Original Size

An increasing number of tweets contains images uploded to twitter. Here is one example:

A particular example

I assume that you know how to find out URLs of images that are used on a web page.

The URL of the image you see in the tweet is https://pbs.twimg.com/media/A0BRGqGCcAEBdHW.jpg with the dimensions 600px × 428px (scaled to 435px × 310px).

If you click on the image to obtain a larger version you are presented with https://pbs.twimg.com/media/A0BRGqGCcAEBdHW.jpg:large with the dimensions 1,024px × 730px. This still isn't the original image.

I then made a well-educated guess and tried
https://pbs.twimg.com/media/A0BRGqGCcAEBdHW.jpg:orig and it actually worked; I got the original size image with dimensions 2,048px × 1,460px.

So all you need to do to obtain an original size image is to append »:orig« to the URL of the small version of the image.

Note that this only works for images uploaded to twitter not for images hosted on flickr.

Here is one example: https://twitter.com/VirtualAstro/status/241683461155475456 shows a nice photo of a blue moon; the 3 MP image can be found at https://pbs.twimg.com/media/A1qS3JvCQAE0QPv.jpg:orig

Easily Brighten Underexposed Areas of a Photo

In Overlay an Inverted Layer Onto a Photo to Brighten Underexposed Areas, PetaPixel shows how to do precisely that. I applied the method to a quite arbitrary underexposed photo and this is what I got:

Original image

Lit up using overlay method

Lit up, white balance applied

White balance only

A nice method indeed and it should work with any image processing program that's worth being used – in the article it's Photoshop while I have been using the Gimp.

FxIF

FxIF (Firefox exIF) allows you to view meta information data contained in JPEG images. Most digital cameras add EXIF data to all images you take and much editing software adds or allows you to add more informations on the picture and you the creator.

Open Image In New Tab

Open Image In New Tab adds a context menu item for opening images in new tabs.

Video DownloadHelper

Video DownloadHelper makes downloading videos, audio and pictures an easy task. It supports hundreds of sites.

Shrunked Image Resizer

Shrunked Image Resizer is an add-on for both Thunderbird (available here) and Firefox (available here) that makes your photos smaller, so they don’t take forever to email or send to websites.

Do you recall Obama’s Change campaign? Here is a friendly reminder from two men who would like some of the promised change.

The original photo has no known copyright restrictions.

Photo postprocessing

I took a photo of a plant with very nice flowers but unfortunately quite ugly brown spots on its leaves.

I then tried out how the same photo looks if I colorize it (in GIMP it is Colors → Colorize… with Hue 30, Saturation 50, and lightness 0).

As you see the leaves now look much better but the colorful flowers now do not look as bright as they did before. I therefore added a transparent layer to the first image, pasted the colorized version to this layer and then removed the colorized flowers so that the original version shines through. Here is the result of this operation:

Finally I applied some cropping and got:

I like the final result.
