My most recent Photoshop tutorial for PetaPixel covers removing and replacing a background in an image. You can check the entire tutorial here: https://petapixel.com/how-to-remove-background-in-photoshop/
Using Photoshop to remove the background in an image so that you can replace it is one of the most frequent things for which it was used, and might still be. The actual placing of a new image for a background is relatively easy. The heavy lifting comes from making a good selection of your subject as this will be used to remove the unwanted background for replacement.
In this article, we will show you how you can use Photoshop to remove a background from a photo. The majority of this article will focus on Photoshop’s selection tools and techniques that can be used in order to perform a background replacement along with some tips on how to adjust the final image to make it look realistic.

Using Curves in Photoshop | Petapixel
My first article for PetaPixel just dropped on their site this morning. This one deals with using the Curves adjustment tools in Adobe Photoshop. Curves is a very powerful tool and it was hard to keep the article as short as it is (it’s not brief!). For those of you who are new to image editing, or you’re well versed but just don’t venture into curves much, I hope you find this article interesting and useful. Keep in mind the principles in this article will apply to curves adjustments in other applications such as Gimp, Affinity Photo, and others.

When thinking about the Curves tool in Adobe Photoshop, the phrase “With great power, comes great responsibility” is a thought that comes to mind. Curves is the most powerful tool in Photoshop for adjusting brightness, contrast, tonality, and color. All that power comes at a price and if not wielded carefully it can easily wreck an image. That’s why it’s best to work on a copied layer or use an adjustment layer when using Curves.

Just Backup for a Second!
Backing up your images.
I see a lot of discussion across various forums and Facebook groups about backups. Usually in the form of “What backup system/strategy/etc. does everyone here use”. As with a lot of topics on the technical side of digital photography there is rarely a single answer that is best for everyone. However, there is one thing that I feel should be implemented in any backup strategy and that’s redundancy. To illustrate this I wanted to discuss my backup strategy and how it works.
My backup plan includes three backup locations with two if them updated daily and the third updated each week. First, I have a NAS (network attached storage) device on my local network at home. A NAS a dedicated network device that contains a hard drive (or drives) where files can be written to or read from over my home network. While it is nearby in my home, it is not physically connected to my PC. If something were to happen to the computer itself I would still be able to access the backup data from my home network. This backup runs everyday when the computer is idle.
Photoshop Scrubby Slider Fix for Windows 10 and Wacom Pen
Over the past year or so I have noticed an issue with using scrubby sliders when using Wacom pens in Windows 10. Trying to drag a scrubby slider will result in the pointer snapping back where it started depending on how much you move the scrubby slider. This behavior is very annoying and causes one to switch to the mouse or type in the values needed. Either way it slows down the workflow when using a pen.
I was asked recently by the editor of a website I write for to please make sure the images I send him are saved at 72 DPI. As soon as I saw this I thought “uh-oh, here we go..”. I politely agreed to make the change to the setting (it’s easy enough) but asked what the reasoning behind this would be. I had a pretty good idea what the response would be, but I wanted to make sure. A few minutes later I received the response that I feared. He said it would help the images load faster when viewed on the web site.
I was correct in my guess. The editor was under the impression that a reduced DPI setting would decrease the image file size which in turn would facilitate faster loading times for images from his web site. This is not an uncommon misconception but one I felt I would like to clarify. This editor is intelligent and a great guy to work with so I wanted to help him understand. This setting would not affect the images in the way he thought they would and while it would not harm anything being set differently, it adds an extra step in his workflow at times that he doesn’t have to take.
