Secondary Color Corrector in Sony Vegas Part I – The Girl within the Red Dress




This is the primary in a short series of articles in which we will explore a few uses of secondary color correction. While that is written through a Sony Vegas consumer for Sony Vegas customers the simple concepts will follow in different non-linear modifying packages as well.

The secondary color correction plug-in in Vegas is a completely powerful tool with a huge range of makes use of from very subtle corrections to inventive or even comical consequences. Before we get into reaching precise results, let’s take a look at how the plug-in works. The layout is split into sections pinnacle and bottom. The backside phase defines what elements in the photo you want to be struck by the impact. The elements may be selected by means of defining any mixture of luminance, saturation or hue levels. There is also an eye dropper device so that you can be included in a future article. The pinnacle phase defines what you want to do to the ones decided on elements which could include converting the hue, saturation, gamma, and extra. In this first article, we will be proscribing ourselves to the hue settings in the backside part and the saturation putting inside the pinnacle element.

The Girl in the Red Dress

If you have seen the Spielberg movie Schindler’s List than you no doubt will recall the scene with the woman in the purple dress (or coat). In an, in any other case black and white film Spielberg chose to colorize the little ladies red get dressed to draw interest to her at an emotional point inside the film. While he probably did it the old school manner including color to black and white movie as became regularly finished with vintage pics, you could reap the equal impact using your secondary shade correction. In reality, this system offers you a massive head begin via including a “Desaturate all but Reds” preset. Don’t contact that preset! While within the maximum simple scene the preset would possibly paintings, in maximum cases it’ll no longer get you an expert result all by means of itself.

Let’s start with choosing your scene. If you’re shooting something scripted and might plan ahead it’ll be smooth. Simply ensure the crimson get dressed (or blue flower or some thing you are the use of) is the best issue within the shot with that coloration. Avoid having some thing with different sun shades of the identical shade and watch out for mild reflecting off the purple get dressed and affecting another object. If you could control all that then congratulations you can just use the preset. Now, for the relaxation of us. I will now and again employ this effect in wedding motion pictures leaving simplest the bouquet or yes even the little female’s dress because of the only colored detail within the scene. Yes it’s too obvious, yes it’s a touch cliche, however, it looks accurate. Although if the flower woman was surely sporting a red get dressed I might not suggest putting a right away visible connection with a holocaust movie within the wedding ceremony video. Anyway, you can not use this effect in just any vintage shot. There are commonly too many objects of the equal coloration or mixed colors within the shot, so you are seeking out a shot where one detail already stands out due to the fact it is an exceptional color than the entirety else.

Alright, so you’ve determined your shot. What we want to do is (as the preset says) desaturate all but purple. The pinnacle part of the plug-in defines what we want to do, so in this situation virtually flip the saturation down to zero. Assuming you failed to cheat and start with the preset you currently have a black and white photo. Now within the backside half of-the plug-in, we want to outline what we need to be affected. At the instant, with the aid of default, everything is affected so we are able to alter it to tell it exactly what now not to affect (purple).

Since we’re looking to do away with the color crimson from the desaturation effect we are able to most effectively be managing hue. You will note the width slider is all of the ways up at 360. For a visible reference of what this represents just have a look at the chrominance color wheel on the top. With the width at 360 we are affecting all 360 degrees of the coloration wheel, consequently, everything has been desaturated. You may also note that the “middle” slider is set to one hundred eighty. This represents the attitude of a hundred and eighty ranges on that same coloration wheel.

If you switch down the width putting you may see blues and magentas showing up first. Referring lower back to the chrominance shade wheel you will see that with the middle at 180 and the width right down to one hundred eighty we’re now telling it to desaturate everything on the left aspect of the wheel. So, to depart the reds saturated you need to move the middle slider to round 260 levels so you are desaturating the whole lot on the opposite aspect from purple. Now you may alter the width till just the crimson dress is colored. You may want to please tune the center barely if the dress is slightly more orange or purple.

There, you probably did it! Oh, wait, some thing else in the photograph that didn’t look pink before now has red splotches in it? Try adjusting the smoothing. This will stretch the boundary of what is being desaturated and blend the borders a touch.

If you continue to have that one stubborn purple spot someplace in the photo that you don’t want then it’s time to hire a 2nd effect to easy matters up. This can get a little complicated if the camera or purple factors are shifting round lots, but it is able to be executed.

First, right click at the tune header and create a duplicate tune (or replica and paste the occasion on a tune immediately under the original). On the lowest track set the width of the impact again to 360 for a black and white event (or use one of the many other strategies to be had to show it b&w). Now quickly mute the bottom song to make it less complicated to look at what you are doing. In the pinnacle, music add the cookie cutter plug in. Set the technique to “Cut away phase” and decrease the scale till it’s miles huge enough to cover up the ugly purple splotch you want to remove. Add a touch feathering to keep away from any artifacts and cover up that more purple spot together with your big black dot. Now unmute the lowest song and you have a female in a red dress and the greater red in the scene has been eliminated.

Just one greater tip. If the red factors in the scene (or the digital camera) is transferring so the patch isn’t always in the right vicinity you may need to animate it the use of keyframes. I’ll keep keyframe animation for another tutorial.
