About the Image(s)

Greetings Group 26. I'm happy to be joining your group and looking forward to receiving and giving feedback on photos. For my first posting here, I wanted to tell you about an exciting toy I recently bought and how it's used. I follow a number of photographers on YouTube, and one of them spoke about a product called "ColorReader EZ". I believe this tool was developed primarily for architects, contractors, home owners, and others who want to be able to sample and match an old painted wall color. But the fellow who described it for photographers explained that you can also use it to choose background colors for portraits. The way it works is that you hold the unit against a piece of clothing and the name of the color will be sent to your smart phone. But, in addition to that, lots of other information is sent. The RGB and Hexadecimal code for the color is provided. Then, 4 other sets of colors and info are also shown: the complimentary colors (directly across the color wheel), the Triad colors (2 other colors, each 1/3 the way around the chart), the Analog colors (adjacent to the chosen color on the chart), and finally the Monochromatic colors (same basic tone). I have usually used a white or black background for portraits, but this tool now lets me choose other colors that will support whatever the subject is wearing (or conversely, suggest clothing colors to the subject that work well with a fun background color). For the image I've submitted here, you'll meet my "never complains" model Demi. $12 on Amazon and I can practice portraiture any time I want. I took the photo with a white background, sampled the shirt color, and then chose a complimentary and an analog color. A few minutes with Photoshop and I now have two much nicer looking backgrounds for my portrait.

Welcome to the group, Bob!
So, now a mystery for me is solved! I have forever wondered how old paint was ever successfully matched. I consider it magic! I save files of photos I've taken just for backgrounds of varying colors and textures to use when creating artistic images from phone photos and from my regular camera (also mirrorless). I like many apps for creativity and will definitely check out your neat discovery!   Posted: 02/08/2021 20:09:52

Welcome to the group!
I like the experiment you did, and finding out about color schemes. Well performed "portraits" with interesting color schemes. Well done!   Posted: 02/08/2021 22:20:04

Bob, welcome to the group! Thank you for sharing this technique to change backgrounds with tones that match the main subject. It's interesting how changes in the background give a completely different feeling to the same subject. Maybe I should start trying it.   Posted: 02/10/2021 21:34:11

Welcome Bob! I like your ideas of changing the background colors according to the color wheel. I have 2 questions: 1) Does the tool give the HSL value for you? 2) Does it work with 8 bits or 16 bits?   Posted: 02/12/2021 10:04:44

I'd have to say "no". It provides the Red, Green, Blue settings and the Hexadecimal settings as well as L,b,c (L* indicates lightness, a* is the red/green coordinate, and b* is the yellow/blue coordinate). But it provides those values for the color you scan as well as the 4 suggestions for complimentary colors.   Posted: 02/12/2021 14:31:35

Hi Bob. Welcome to our group.
Thank you for this tutorial on color balance and sharing your use of these additional "toys" to help our creativity.
We look forward to many interesting images from you in the future.   Posted: 02/12/2021 13:28:11

Interesting info I need to store away for a time when it could prove handy.   Posted: 02/17/2021 11:15:38
