iPhoneography Apps Bonus – iColorama Range option

There was a recent question on the iColorama Facebook page about the purpose of the Range command. I decided to put together a quick blog entry to help explain. There is a silent video embedded here, and the explanation of that video is right here.

Range is used to build a mask. In other masking tutorials, I have explained how to use the Threshold command to build a black and white mask which can then be re-imported. When you create an iColorama mask, black reveals the changes you are making, while white conceals those changes. Black reveals, white conceals. When you use the Threshold command to create a mask, as I show in the beginning of the video, the resulting blacks and whites are based on the luminosity, or brightness, of the underlying image. So as I adjust the Threshold, you can see that both the dark green leaves and the dark trunk are turned to black, while light green, blues and grays are turned to white.

But what if you want to mask certain colors instead? When you want to change the greens in the image, but not the reds of the same brightness, you turn to the Range command. I use the Blacks color picker, and the eyedropper tool, to pick up a green color, and everything turns black. Then I pick a light blue from the sky with the Whites picker, and the mask begins to take shape. I choose another color with the Whites picker, and another green with the Blacks. I Apply those changes. Then, since I know that I will not want the changes to apply to anything in the lower part of the image (green or not), I paint white over the bottom. Then I save the mask, return to the original photo in Steps, and re-import the mask in the Brush Mask area.

.

My first change uses the Hue command to change the color of the leaves to pink. The resulting image is below.

Of course, just because I use color to determine the mask doesn’t mean I have to change the color. In the second example I use Tensor and Painterly>Van Gogh 1 instead.

I hope that that gives you an idea of what Range can do for you! Enjoy!

iColorama Guest Column – Watercolor & Sketch – Heide Hoffman

Heide created a very nice tutorial about creating “unfinished” watercolors. That look has Edges that look like a sketch with the image in Watercolor painted in. Take a good look, because it’s a technique that looks great and is relatively easy for those of us with little real painting ability.

.

When I first saw Heide’s video, I thought, “Well, of course, you have a nice grungy paper background to use for your painting.” But I realized I could easily make my own in iColorama with just a few tricks. So I created my own paper.

And then I used Heide’s technique to create this.

So I put together a video to show my “paper” techniques. Enjoy!

iPhoneography Apps – Colorizing B&W images with iColorama

I recently responded to an art challenge by colorizing a black and white photo in iColorama, and was asked several times how I went about it. The video tutorial this week goes through the process of creating a different image, the one seen below.

iColorama Guest Column – Compose – Heide Hoffman

This is the last of the guest columns that I have right now. Heide gives her own take on Compose. I am also including a “rerun” of my own video on Compose.

First, Heide.  (Time for you to make a new one!)

.

Then, in case you haven’t had enough, here’s mine. It also has some hints about textures.

iPhoneography Apps – iColorama Procedural: Bottled

iColorama is an app that thrives on experimentation. You see an effect and think to yourself. “How can I do that in iColorama?” Or you stumble upon an effect you haven’t tried before and think, “How can I use that?”  It was a combination of those two questions that led to the image I will be recreating in the video tutorial today. The image is called “Bottled”.

iC15v_01

The resulting video, which uses in the neighborhood of twenty different options, runs just over 17 minutes. I realize that will be too long for many of you, but believe me – there’s a lot going on and I fly through it.

Please let me know if you have any questions about the techniques used. Enjoy!

iColorama Guest Column – Chroma – Heide Hoffman

Here’s a feature that is familiar to everyone who watched a weatherman wave at a blank wall as if there was something projected on it – Chroma. It can make for some interesting blends when you use it in your artwork, as shown by Heide Hoffman.

iColorama Guest Column – Stamped Brushes – Heide Hoffman

Another guest video from Heide. This one is on Stamped brushes, and has many tips for all brush types. Over to Heide:

iColorama Guest Column – Blur – Heide Hoffman

Here is Heide’s third video. This one covers patterned blurs, which are fascinating.

.

How would you use them? Often they can be used in abstracts. But consider, also, that what are textures but abstracts? Usually low contrast abstracts with no huge color changes, but abstracts none the less. Just as an example of an abstract, I made a few brush strokes in Paint mode with some Water brushes.

Next I applied Blur 28, and fiddled with the Direction and Radius sliders.

HBlur_0

Next I used Style>Painterly>Painter 2, Style>Tensor, Effects>Sharpen>2 and Effects>Raise>2.

HBlur_03

Finally, I built a background using Blur again: Preset>Gradient, a couple of Textures, Blur, and Water-B (in the soon-to-be-released beta). I used Effects>Blend to bring in the brushstrokes, then Tone>Enhance 4.

HBlur_04

Kinda nice for a couple of minutes’ work. Of course, you don’t have to limit yourself to abstracts. How about a surreal background blur?

HBlur_05Just experiment!

iColorama Guest Column – Stamp – Heide Hoffman

Second in a series of guest articles by Heide Hoffman. This is the first video Heide produced, and it covers a feature I covered in June of 2013. Seeing it at work in a video might be helpful to you, so check it out!

iColorama Guest Column – Tritone – Heide Hoffman

About six weeks ago I mentioned that I would be throwing enthusiasm noted open to guest columnists for iColorama tips and tutorials. This is my first guest column, from Heide Hoffman. She creates video tutorials that emphasize the value of playing with settings and sliders to get familiar with the capabilities of iColorama. She started with an entry on Preset>Tritone. I’ll be adding her videos here over the next several days. Enjoy!
