Get Rid of Banding in Photoshop with Just 3 Simple Steps!

  • Post comments:0 Comments


so there are three things we need to keep in mind to fix and avoid banding in Photoshop for the first one being always work in 16bit even if you export it in 8 bit work in 16bit here’s why so here’s a simple gradient from dark blue to a little bit lighter blue so if we create a curves adjustment lay keep in mind this is 8 bit right here if we go a little bit extreme like this you can clearly see the banding right here now it is 8bit at the moment as soon as we change it to 16 bit by going to image mode 16 bits per Channel have a look it goes away I don’t know how YouTube is compressing this video but you can see the difference and you get the point so when you’re working with 8bit and start to stack up these adjustments if you have a lot of smooth transitions in your image it is very likely that it can create banding like this that is why I recommend working 16bit if you’re concerned about banding and if your image has a lot of those smooth transitions the second thing to keep in mind is that banding always happens in areas that have lesser details and smoother transitions for example right here where the mountain is you cannot see any banding but right here in the sky you can see the banding because there is not much detail and the transition is smoother so to remove it we can blur it but if we simply blur it by the way first of all this is 8 bit let us first change it to image mode 16 bits per channel so if we simply blur it by going to filter blur and then gausian blur everything is going to be blurred right here the banding is being fixed but we are losing details in the mountains as well so how can we selectively apply blur where we can apply blur in the less detailed areas and not apply blur in the more detailed areas there is a blur like that and we call it surface blur for it with the background layer selected press control or command J then go to filter convert for smart filter so that we can change the blur amount later now zoom into an area go to filter again blur and this time let us choose surface plur now these are at the exact same settings that I wanted because I was practicing before yes I do practice too anyway let us increase the threshold all the way to the right hand side first and then decrease the radius then slowly and gradually increase the radius and stop at the point where the banding goes away you can even zoom out a little bit to check all throughout all right so I’m just going to go ahead and slowly and gradually increase the radius so at about I feel at about 40 most of the banding does go away especially from around the edges now let us decrease the threshold so that the banding doesn’t come back but all of these details do so if we decrease it too much even the banding comes back a little bit as you can see little bit lines here and there so right here you can see the banding too so play with this number see what works best so I guess maybe nine or 10 or possibly we can even get it to eight let’s zoom out and see if we do have any banding we have some banding here but that’s fine most of it is gone and we have all the details too hit okay but there is of course a limitation to this technique it also blurs out a lot of other detailed areas so here’s the before and here is the after we didn’t want to add all that softness all throughout we only wanted it on the sky so hold the altq the option key and click on the mask button to create a negative mask so that we can paint on areas where we do want it let us take the brush make sure it’s a soft round brush with white as the foreground color just roughly paint over the sky and you can even dig in the edge a little bit and that is the advantage of surface Flur there you go see the details are not being harmed as much and now you can paint the entire thing by the way you want to make sure you painted it all so hold the ALT key or the option key click on the mask to view it and you want to make sure everything is properly filled build in I’m so sorry about the construction in the background my neighbors I don’t know what they’re building that is definitely causing banding in my head anyway when you zoom out you do see some signs of banding in the sky for that we would need some extreme blur since we have taken care off the edges we can go a bit heavy-handed press Q for the quick mask mode and you can make a selection using whatever method you please I’m going to choose a soft round brush and just going to paint this area right now we are in the quick m mask mode you want to make sure the smoothness is smoothing actually is zero stay away from the edges stay very much away from the edges like this and fill up the entire thing maybe you can go a bit closer like that that is fine now press Q again to turn that into a selection now we wanted to select the sky this is just the opposite so press control shift I command shift I to invert the selection now with this lay selection selected you can press control or command J and simply blur the area first again do not forget go to filter convert for smart filters so that you can change the values later filter blur gaussian blur a value of 72 already looks good but slowly and gradually increase it to the point where it goes away and of course it would be 72 because I applied it before or 70 Works to hit okay and there you go properly gone but there’s a problem with that and that brings us to the the third thing we need to keep in mind and that is we cannot leave it this smooth it just doesn’t look realistic we need to have some kind of texture some kind of grain so now you have the option to add a little bit of grain just on that area or all throughout the image it’s your call for this example we are just going to press control shift n command shift n the neol layer dialog box will show up change the blend mode to Overlay now keep in mind you need to check fill with overly neutral color hit okay this will create a layer with gray in it now now since overlay is a blend mode which hides everything that is 50% gray you don’t see anything right here if it were normal you would see this anyway let us change it back to Overlay and before we apply any filter let us not forget again go to filter convert for smart filters you can also right click convert to Smart object same thing I’ve even made a keyboard shortcut for it and we talked about it in this video anyway back to this one let’s go to filter noise and add noise let us go for not so high8 you can choose uniform or gaussian that’s up to you I’m going to choose gaussian monochromatic that is important hit okay but now there is a problem the noise is way too sharp if you like it this way you can keep it this way but I’m going to go to filter again blur and then gaussian blur again and for this one add about 8 or 6% blur pixel blur and hit okay the noise is so much better and I love the texture in there but it is too much so let us decrease the opacity and just add a little bit of it how about 32 let’s keep it 32 this is slightly little texture looks good all throughout the image I love the effect of it now let us zoom out and let’s take a look at the before and after so here is the before and here is the after by the way just to do a little bit of promotion if you have the Pix imperfect compositing panel you can open up the structures section and create a grain from there directly so let us turn it off and click on the plus button it already creates a Green Layer and the best part is it is adjustable you can adjust the size of the grain from right here you can not sorry the amount of grain the size of the grain from right here the irregularity from right here everything is adjustable you can even control whether you want the Green in the highlights or not so if the blend if is all the way to the right hand side the grain is applied all throughout but if the blend if is all the way to the left hand inside the grain is more applied in the shadows and less on the highlights as you can see less on the highlights and more on the dark areas so you have all that flexibility with pix imp perfect compositing panel please do check it out the links are in the description so there you go the three things we need to keep in mind to fix and avoid banding in Photoshop the first thing is always work in 16 bit if you’re concerned about banding the second thing is banding is something you usually see in areas with lesser details with smoother transitions so find a way to apply blur so that the areas with details are not affected and the areas with smoother transitions are affected and for it you can apply surface blur and further masking if you need to blur more you can use masking and gausian blur the third thing is don’t leave it completely smooth add a bit of texture it can be anything in this case we added some grain if it’s a backdrop of a model you can add some concrete texture you can add some Stones that’s up to you it’s your creativity so that’s all there is for this video I I hope it helped and if it did make sure to give us a like and also don’t forget to subscribe and not just subscribe ring the bell so that
