Easily Add Color To Black And White Photos
This post deals with the program they offer.
Picture Colorizer - https://imagecolorizer.com/picture-colorizer.html
I gave it a shot. So I used my own mug. You people with smartphones have it easy, taking a selfie with a digital camera is a bit aukward. I finally got a shot that probably won't give too many nightmares. :-)
The first thing I had to do is make it black and white. I did this in PhotoFiltre 7 by clicking on Filter then Aged effect then Black and White. If I used the Old photography effect, it's much like Sepia, a strong yellow tint. But the end results basically the same.
So I saved the photo and then opened it up in Picture Colorizer. It supports drag and drop. And then I just clicked on the third icon in the top row, labeled Colorize! It only took a few minutes. The bar under the picture turns blue and will tell you when it's done. On the right- hand side of the program you can play with the controls like Brightness, Contrast and so on.
Then click on the Save as button, blue, bottom right-hand corner. This will open a preview window, I just clicked on the middle option Save Colorized Photo.
The following is the result. Number 1 is the original. Number 2 is the colour removed. Number 3 is the colour added with Picture Colorizer. Before I did this one, I tried a few old family photos and they came out pretty good to. One thing I noticed, if you look at the very bottom of photo number 3, you will see the company logo and name as a watermark (only on the free version of this program with larger pictures). I did some family pics, the smallest being 286x234in size, and no watermarks appeared on them.
