Background remover in Affinity Photo 2?

[albertkinng]

In Apple's Preview app and in Keynote app you can remove background with a click or click and drag like instantly. Recently a friend show me how he removes a background with Pixelmator Pro, literally one click and everything around the object is gone. Knowing that Afinity Photo 2 is a powerful image editor and is marketing for the Pros, I need to know if there's a similar way to extract an object or delete a background with it. In the latest iOS update, I can touch an image on any photo on the iPad and copy just the person without the background instantly. That's how I'm doing as part of the workflow with Affinity Photo 2 on iPad, but today I was trying to do a fast edit on a picture and didn't find a way to achieve this. I literally Airdrop the pic to the iPad and copy the image with one touch and paste it on Affinity Photo, but it has to be a faster way on the desktop version, right? Well I learned you can do the same thing using certain apps on macOS like Preview and Photos and so on... Why I can't find a way to do it inside Affinity Photo? Pixelmator is using the Apple's API, obviously! Am I doing something wrong? Is because Affinity runs in Windows too and can't take advantage of macOS capabilities? Any idea of how to remove a background with a click or click and drag will be appreciated.

I'm interested in this too. Seems like a lot of effort has been put into background removal lately. Recent iPhone "pro" models even have a lidar scanner to collect depth information, primarily for background blurring and automatic dodge-and-burn shading or something. A bunch of "aWeSoMe AI" type services have popped up trying to do this too.

The most sophisticated services even charge quite a bit of money for just this https://www.remove.bg/pricing

Fotor seems to have problems with "complex" backgrounds (where the subject and background are too similar in color, or the subject has wispy thin hair etc) even though it's another sUpEr AI type service.

I'm also curious what the difference is in Affinity Photo between the background erase tool and the selection brush because while the background erase tool seems to work pretty well, sometimes you just want a mask not a destructive pixel layer edit.

By buying the three "flagship" Topaz applications I seem to have gotten a license for Topaz Mask AI (I can't figure out what's up with their licensing right now, they seem a little disorganized as to creating lots of apps and trying to sell them one-off without really explaining what they're thinking in licensing terms) but Mask AI seems a bit broken on my system at the moment.

I recently got a project to turn 25 pictures into black and white with colorful light flares passing around the worker model person with shattered particles around their bodies. The client send me the photoshop add-ons and brushes and specifically told me it got to be done in photoshop. 
 

I did it all in Affinity Publisher. Using all the apps in one give me the versatility and productivity I need to achieve this task and I didn’t use either the brushes or the add-ons he provided. One of the workflows to get the person out of the picture was super fun using the Affinity Share option on the Menu bar, basically I shared it to Apple’s Photo app and with a right click I copied the selection and pasted to the Affinity project like, instantly! 
 

I will try to use Keyboard Maestro to see if I can create a macro that can be helpful to this kind of workflow in the future.

Ventura's background remover seems to be fairly good.

Having a background remover tool would be great.  I started doing banner pictures for my daughter's sports teams.  I can get the white background removed - just takes time - nothing like the one-click options on many online tools.

If you’re background is white, use filters > erase white paper. Otherwise the selection brush.

If you have a Mac use keynote app or the right click to save main person: https://d.pr/v/KF44b1

I've tried some of these automated tools and while they work for a good number of images, they don't work all that well on edge cases, which is often when we need them the most. 

There are quite a few different techniques one can use to manually mask out backgrounds depending on what it is you're trying to mask out. 

For difficult daylight sky removals, where there are trees or lots of details on the skyline, I generally use a luminosity mask. This requires multiple steps, so it's not a click and drag, but it gives superior results in my experience. 

In V2 I still do this manually as the new luminosity mask is a live mask and can't be painted on (there are workarounds for using the new luminosity mask, but it ends up no faster than the method below).

Here's my workflow for this particular type of mask

• Select --> Tonal Range --> Select shadows
• Click on Channels panel. Right click on Pixel Selection and choose Create spare channel
• Now do the same and select midtones instead of shadows
• In the Channels panel, right click Spare channel and choose Add to pixel selection
• Now use the use selection brush in subtract mode to deselect areas inside your foreground (and vice-versa if anything in the background is incorrectly selected)
• Once you have your selection, choose Select --> Grow selection by 1 pixel and then feather selection 4 pixels or less. This will leave a slight halo around your edges if your sky you're masking out is much lighter than the replacement sky, but if you don't do this, then you're likely to get edges that are too sharp and lead to a blocky effect. I never grow by more than one pixel and sometimes feather by less than 4 pixels, never going above 4 (I feathered by 2 on the image below)
• With the selection still active, click on the mask icon to create a new mask layer from the selection
• Select the mask layer then alt-click on it to see the black and white mask
• In sections where the mask should be opaque, paint over it in white if you missed. Ditto for black. Be careful not to go near the edge. We'll deal with that soon.
• Now click off the layer then reselect the mask layer so you can see the image and not the B&W mask layer
• Reduce brush opacity to 50% and set brush blend mode to overlay (you can start with even lower opacity and just go over it more times)
• Zoom in on the border between sky and background and find any areas where there is haloing
• Now apply the brush (in black) over the edges to reduce the haloing. Make sure you're painting on the mask layer. You may need to increase or reduce brush opacity on the fly. The overlay blend mode is key to getting this step right. You can also apply a curves adjustment to the replacement sky (a U shape, either inverted or not depending on whether you want to reduce or increase the luminosity of the replacement sky - this also helps to eliminate the haloing by reducing the exposure difference between the edges of the foreground and the replacement sky)
• As a final step, and not always - it depends on the image, I might adjust the blend options for the layer, something like the following. It also helps in reducing the haloing and giving a more natural looking transition. This won't work if you have very strong highlights in the foreground part of the image (as it will then reveal a portion of the replacement image on those strong highlights. The exact shape of the curve would depend on the image. 

Needless to say, you should get your image looking right before swapping out the sky, as doing this post swap would likely just accentuate the transition border.

Below is an example image where I used this technique to mask out the sky. First image is a crop from a 400% zoom to show the result, the second is the source image and the last is the final, processed version with the replacement sky added.

Your post is incredibly good. Very well explained and super helpful. I wish all the contributions on this forum were exactly as yours so we can have a community of professionals looking for unity and mastering the tools we choose to achieve our goals. I barely find useful comments like the one you shared with us. Most of the time is blinded fanatics that doesn’t want to accept the flaws or misbehavior of the apps and pretend that everything is find. Keep your posts coming, my friend!

rvst,

thank you so much. Very, very good content and precisely explained. I'm missing a bit TK9 masking tools which i used a lot in PS.

 

regards

I am a new user coming from using Pages.  Over there, two clicks and the background is removed.  On this program, I can't even find 'Filters'.  I type in 'Filiters' or 'remove background' in the Help and get nothing.  How do I get to Filters?

I found that most articles say to go here and then there, but how does one get here and then there?

I just want to remove the while background from the attached picture

You don't need affinity photo or any tools to remove backgrounds if you are using a Mac you just need to right click and select remove background and that's it !

Which Affinity app are you using, Affinity Photo, Affinity Designer, or Affinity Publisher?

What version of the Mac OS are you running? I ask because I do not have a "Remove Background" item in Services on my Mac running Catalina.

Catalina is over 5 years old. I don't even know if you can use Preview to delete a background either. What do you use your Mac for?

Yes I can via "Instant Alpha" but it is not a one-click solution.

I am still using Catalina because some of my old apps won't run on later versions, or not without expensive budget-busting paid upgrades.

I started to feel like I was losing it when I told someone recently that I still have two Mac Minis from 2012 running in my office, and they seemed horrified by the idea. I felt so awkward that I ended up saying, "Just kidding." Do you think there are others out there like us? 🤣

I have the original Bondi Blue iMac G3 from around 2000 still runnable but rarely running (and nothing much useful installed on it) at our home office and it mostly gets amused admiration. I also have a PC from around 2010 that has fully operable Adobe CS4 Suite installed on it, which could still be used for most that I do today with modern computers (2 such acquired only this year, one PC and one Mac). We additionally have two desktop PCs from 2014 running Windows 11 Pro with Adobe CS6 Suite installed, in full operation, and additionally two MacBook Pros from 2011 which were mostly used via their Bootcamp partitions to run CS6 Suite apps (now transferred onto more recent native PC laptops, and fully operable), so I have never been vulnerable to Apple-created auto-obsoletions (like change from Motorola to G3/G4 to Intel to Silicon Mac, or support for 32-bit apps dropped). Nowadays most software comes with multi-platform licenses so we are not likely to suffer from this kind of issue in the future, either, no matter what ingenious novelty is invented next, on either platform 🙂

Isn't it much the same which kind of shovel is used as long as it is more or less suitable for the task?

I inherited a stunning vintage accessory piece from my mom that looks incredible on her desk. Currently, I own three Mac Minis: two from 2012 and one M1 from 2020, all of which are in full production mode. One is dedicated to audio production with Protools 10 and all the necessary peripherals, while the other runs Adobe CS4 for specialized tasks. My M1 is exclusively for graphic design. Next year, I plan to invest in a MacBook Pro M1 and a new iPad Pro M1. Recently, two of my employees left for another agency in search of higher pay, leaving me in need of a portable solution for emergencies until I can find new team members—if I do, considering that AI has already replaced one of them flawlessly.

How's this for vintage models? My forth(?) Mac was a UMAX SuperMac S900 licensed clone bought because the Power Mac 8600 I wanted wasn't available at the time I needed to replace my old Mac Quadra 660AV.

I still have the SuperMac gathering dust in the attic, although I'm not sure it still will start up.

I recall encountering other official clones. Do you remember the brand?

I did not remember any others besides the DayStar Genesis & the Power Computing's "Power" series,  but Wikipedia has a long list of them. 

FWIW, by the time I bought my SuperMac UMAX was the only company that still was licensed by Apple to sell clones.

I sympathize. My sense is that this is always going to be how it is. If you need to run old programs, you keep your old machines running when you get a new one.

(In practice, my garage aka computer graveyard is cluttered with I think six old machines that haven't been turned on in years.)

I haven't tried this, so I can't vouch for how well it works.

Try at your own risk etc

What a great step by step video! Thanks! I definitely will do it on one of my legacy Macs. The other strictly needs Yosemite! I needed 🥶 in ⏱️
