Photoshop :: How To Take PNG And Increase Its Opacity
Oct 6, 2012
I have a PNG file with some transparency. I need to paint in some opacity in the alpha channel. How can I achieve this? In the Channels window, I can access the R, G and B channels just fine, but I need to access the Alpha channel. I need to make my image more opaque in places.
how to increase the opacity of a pixel (without altering it's RGB values)?
It's just soooo BASIC that I fear I'm overlooking something incredibly obvious.
To make it really clear: I have a pixel with, let's say with RGB=(48,33,57) and 25% opacity. How can I make a (48,33,57) pixel with 75% opacity out of that?
I find, right after the brush tool, that's the most obvious tool for Photoshop. I wonder, why this is missing ? Most tools have their counterparts, like dodge/burn or sharpen/blur. So why does the eraser (decrease opacity) don't have a counterpart (increase opacity)?
Using the eraser tool or several other methods I can set pixels in a layer to be semi-transparent. Let's say I save such a layer without history. How do I make these pixels 100% opaque again? Is there some tool that does the opposite of the eraser?
It does it every 4-6 times which is really really often since you brush about 10 times every 3 seconds or so when digital painting especially when shading, lighting, blending, etc with brushing.
Why does it do this? I cant recall when it started doing this but I think it was either when I updated from CS4 to CS6 or maybe it just randomly kicked in. I already updated my drivers and re-installed my tablet.
In the animation I am working on, I need an object to instantly go from 100% opacity to 0% opacity. The problem is, even if you use the opacity of the layer as a keyframe, the object will not instanlty vanish, even if it is only on for the timeruler for a quick amount of time.
I need a tool that will drop from 100% opacity to 0% instantly.
When you merge two identical layers (with solid black-filled shapes) and with, say, 30% opacity both, the resulting layer will be a layer with 100% opacity but with 30% transparent black-filled shapes. How will you make this 100% opaque?
I am using photohsop cs6. I have defined a brush preset and I want to change the opacity jitter for that brush. However, the opacity jitter option which comes under transfer in brush panel is being inactive all the time. How do I enable it?
Does anyone know how to photo shop calculates the resulting color when using brush opacity?
For example If I paint over a section with 100% brush opacity, then go over it again with another color with 100% brush opacity then the new color replaces the old. But what happens if when I go over the first color with a new color set at 50% opacity? How does Photoshop calculate the resulting color?
I want to change the opacity of an item or layer, but that also changes the opacity for the stroke too, How can i change the opacity of an item without effecting the stroke.
This is something that i never really gave much thought - but what value do the opacity parentages really have?
See my assumption was that 50% + 50% = 100%. So if you had a solid black layer set to 50% opacity and you duplicated that layer one would think that it would be solid black again... but no is only 75% black. WHAT?
The other thing is that solid black with and opacity level of 50% over solid white is a true 50% gray which is half black and half white - do to half's not make a whole?
I am part of a research lab that is putting together experiments relating to visual cognition, and I was wondering how exactly Photoshop CS3 achieves opacity. Is it through pixel amount or another method?
I have 20 boxes that have to be linked like a flow chart over a black and white photo. Each box needs an opacity of about 50% white to insert text. Each box needs a 100% black stroke around it. But when I apply the stroke to the box and then lower the box opacity to 50%, the black stroke fades out as well. I can't find a way to allow the 100% stroke to remain 100% black around the 50% opacity box.
If there's an object with a semi-transparent part (without editable layer mask of course), is there any way to make it opaque again without ruining its original pixels?
(For those who know Corel PhotoPaint: I'm looking for the equivalent of "paint on transparency" mode)
I am having a problem reducing the opacity of a photo. When i reduced the opacity i end up with a chequer board of white and grey squares all over the photo any ideas?
Is there any reason the opacity won't stay completely opaque for the pencil and paint tools (and possibly other tools)? I have opacity set to 100% in the options bar at the top as well as the fill and opacity settings on the layers pallette. I can't see anywhere where opacity is being set to less than 100%.
I am interested to know how to create a layer where the opacity is gradually lowered from one side of the pic to the other. What I want is basically the effect you get with the gradient tool but with opacity and not colors.
I was messing around with Repousse (CS5 Extended) and found that it would be nice to increase the perspective severity on my object, much like increasing the Perspective degree value when adding the 3D effect to a vector shape in Illustrator. Is this possible? Or can it be faked somehow?
Well the pest is back with another 3D in CS6 question... I'm attempting to use Illumination on my office ceiling here to simulate light reflecting off a wood floor. As you can see, the reflections don't show up very well. How to increase the intensity of the reflected ceiling lighting in this digital room?
I've been wondering... Since resolution is such an important factor to whether a pic is sharp and clear, how is photoshop able to increase the resolution of the pic? From what I heard, the picture is broken down into more pixels when the resolution is increased. If so, how can it distort the pic?
I also have this senario which I'm facing now... Since it's rather confusing, I have broken it down into Steps...
Steps:
1) Open picture A in photoshop 2) Transformed picture A smaller so that it is easier to work with (less lag) 3) I created some layers and merged all the layers together 4) Copy the merged layer into another Art piece in Photoshop 5) In the new Art piece, I transformed the merged layer back to the original size
As I transformed the merged layer back to the original size, will it become distorted? Or will the resolution remain around the same?
you probably heard this many times but i got a picture and would like to resize an object in the image. for example a car and i would like to make the rims bigger, how would i do that.
I have Photoshop CS and it's been runing well. I believe it was running when 'doing ctrl/Alt/Del to checl processes' around 30,000K or so. But recently I've noticed that the Memory Usuage is at 99.524 before working on any doc. I'm not sure if I tweaked something my computer and I'm sure I didn't tweak anything in Photoshop.
I'm using Photoshop CS5 with a Wacom Intuos 3 and have not had any problems with my brushes before.
Today, however, I started to paint, and noticed that my brushes were acting up. I paint a brushstroke and everything is fine - but when I paint another one over it, it makes the first stroke appear darker, whereas I would want the second stroke to cover the first one.
My brush mode is set to Normal and the opacity is 100%.
I've opened previous files as well to see if it is just about the current file's settings somehow, but the problem still persists. And I don't recall having done anything to change the brushes' behavior before.
In CS6 when I increase/decrease size of my brush using alt+right-click on pen tablet, sometimes I also unintentionally change brush opacity by couple percentage (obviously my hand won't move perfectly horizontally every time I want to do it). It kills flow during work of course and I have to stick to CS5 for now unfortunately.I have only found option for turning off hardness change in preferences.
