Create Wonderful Astrophotography Images With A DIY Star Tracker

Create Wonderful Astrophotography Images With A DIY Star TrackerThe following guest post and videos about astrophotography tips and building a DIY star tracker was submitted by Jason Anderson from Canon Blogger.

 How many times have you looked at the nighttime sky, seen some amazing expanse of stars and just thought, “Hey, now that’d be a cool shot!”? From stars and nebula to comets and asteroids, then planets and galaxies, outer space is still a source of awe and wonder for so many of us it’s no doubt that when we capture images from this overly undiscovered frontier, it is surely to grab the viewers attention.

Well, if you want to retain that viewer attention (and who doesn’t...?) it can help to have images that pop!

response to dynamic loads (by { tcb })The following article is a guest post by Dana Maltby a.k.a. Twin Cities Brightest a.k.a { tcb } an addict to Light Painting.

In the last Light painting installation we saw the huge variety of tools and toys I use for creating Light Painting Art.

SB800 internals  (by udijw)As you may know, I am involved with a secret project. For this secret project I needed dots, plenty of dots.

Introduction To High Dynamic Range (HDR) Photography

Introduction To High Dynamic Range (HDR) PhotographyHigh Dynamic Range Photography (HDR) is a creative technique in which you combine 3, 5 or 7 images shot at different exposures, which are then merged into a single image.

The advantages are far more detail, vibrant color and control of lighting than you could ever achieve by manipulating a single JPG or RAW image in Photoshop.

In the following post Gavin Phillips will cover some of the main (yet often overlooked) aspects of HDR Photography.

(Roll your mouse over any of the images and linger for a second to see how it looked like before HDRing it).

Of course you'll need a camera phone for that. cnflikt uses the notorious, yet old-skooled K800i, but any camera phone will work here.
