The colour temprature is way down approx 10% and so is the luminosit, it is no where near the rcommnded levels. To the extents I have now got a red tint on my screen due to the colour temprature.
So how can i overcome this, can i buy a special lightbulb or kit for the room i work? Or what do I do?
I know what the documentation says that they do, but it doesn't appear to be the truth. For example, if I take my image and overlay it with a 50% gray layer set to Luminosity mode, I would expect to see the hue and saturation of my image, with the luminosity of every pixel set to 50%, but that isn't what actually happens.

Is there a way to only display the luminosity histogram curve? Also, how often would be considered normal to have to re-set preferences?

I m using Photoshop 7.0
I have a digital camera by Pentax called the Optio. It has one of the best features ever which lets you take a standard picture the go in to options and choose to filter out any color except shades of blue or shades of red or shades of green, thus everything else goes black and white. Can someone help figure out how to do that in photoshop?

View 6 Replies View RelatedWe all know the invert function of Photoshop, easy and nice (well nor always but will fix this) to invert all colors.... The downside is than this trick will also invert luminosity... Light area become dark and dark area become light, this can ruin an image!
If you wish to invert an image and keep lighting intact the trick is really simple!
1) Open an image to be inverted
2) Duplicate you background layer (or the image layer), this layer will be used as a luminosity mask.
3) Select your original layer
4) Invert you original layer
5 (Optional) Link and Merge these layers
Done!
Trick : If you invert the luminosity(the copy of the original) rather the than original layer, you will inver the lighting of the image... Its also pretty cool!
I have always used the shortcut Ctrl+Alt+~ to get luminosity selection. It always worked in Photoshop CS3 and still does on my computer, but when I try it in CS4 nothing happens and it doesn't work. Do I have a preference or setting wrong?

I am reading a tutorial about the background eraser, and in this tutorial, on the screenshots, the erased parts are in red. It is the same red than the default one for the mask mode.
Is there a mode to see the mask color instead of what there is beneath the layer ?
Note : Maybe the tutorial author put a red layer beneath the current layer...
I would like to make a color selection and then make a mask of that color. How on earth do I do that?
View 5 Replies View Related1. Duplicate the image which is in RGB mode
2. Change the mode of the duplicated image to LAB color mode
3. Select "lightness" channel in the duplicated image
4. Move it into the RGB image as alpha channel
5. Copy this channel and invert the copied channel
6. Create two HSL adjustments with these two channels used as masks
7. Turn off completely the saturation sliders in the HSL adjustments for desaturating the image
Now, I can not get completely desaturated image after these steps..Is there a leakage between my luminosity masks?
I'm trying to get a better understanding of luminosity masks. Where can I find out just what operations Photoshop is performing when I control click on the rgb composite channel to make a selection (which I then save as an alpha channel)?
My assumption is that the brightest half of the image pixels are included in the selection and the rest are consigned to black. Is that even in the ballpark?
In the histogram palette menu there are red, green and blue histograms to give the saturation of those colors, and a luminosity histogram to give the overall ( greyscale) brightness. There is also an RGB option, presumably to give a composite version of the red, green and blue saturation.
In Levels, however we have the same thing, except there is no luminosity option, only RGB. But RGB in this case cannot be a composite of the three color channels, as we use it to adjust brightness and contrast; in other words it is presumably the same as Luminosity in the histogram palette. Despite this, when I do adjustments to an image the RGB histogram in Levels looks identical to the RGB histogram in the histogram palette. I'm using PS 3 Extended.
Colorizing a photo can be fairly simple using Adjustment layers and Hue/Saturation, what I've never been able to do though, was convert black to white within a photo. The other way around, white to black, is fairly easy to pull with decent and satisfactory results. Black to white on the other hand, seems to give a lot of trouble in maintaining proper and believable luminosity. If I have a black plastic object, for example, that I'm attempting to turn white... through all random experimentation I have done the object either becomes another 'material'... ie. metallic, or the object becomes too washed out (loses detail) to even make the eye believe the change is real and the material is still the original. I do know, though, that people are capable of creating the illusion of all sorts of material and surface through photoshop. So, if someone has an idea on how to 'colorize' and image while maintaining the original and proper reflection of light on the surface of the object,
Attempting to lighten plastic center plate using levels, loses correct material luminosity and becomes metallic
Attempting to lighten plastic center plate, using Lightness/Saturation, loses vast amount of surface detail, becomes 'flat' and washed out
I'm seeing a lot of poster art these days online, and many of them have a really nice textured effect to the color fills. It's not your typical Photoshop filter, however.[URL]...
How is this done, do you think? A custom brush of some kind? Or load a selection and mask the color?I can't find the exact poster right now (that figures!) but sometime this texture looks almost like poor ink coverage, or a bad Zerox copy (low toner.)
How do I change skin color using a layer mashow do I apply the mask if I want just change say an arm or just the face area
View 1 Replies View RelatedI'm trying to replace a colour in PE9 (Enhance > Adjust Color > Replace Color) but it's only replacing the luminosity, not the colour.
For example, I'm trying to replace a pasty white with full red (255,0,0) and it just comes out grey....
I can't find any switches for 'color/luminosity/hue' etc
New action set?
View 1 Replies View RelatedI'm currently recording the median luminosity and standard deviation of luminosity values in various photographs. This has been an ongoing project so I've been working on it for probably the last 4 months. Today I resumed my work and had to go back and check a previous photo that I had already recorded luminosity values for and noticed that the luminosity values that I had originally recorded were different than the values I'm seeing today in the histogram.
The attached picture shows the histogram I'm using (and have been using since I started this project). It is showing a median luminosity and standard deviation of luminosity for a photo that originally gave me this median luminosity value: 75 and this standard deviation: 27.87
I accidentally changed some setting in photoshop that affected the luminosity readings, or if the luminosity values of a photo are estimated by photoshop and thus aren't always the same etc. ?
Is there a way to assign this to a shortcut key?
View 8 Replies View RelatedSometimes it appears that the white/black color combination that is automatically selected in layer mask editing may override the selected color combination outside of layer mask editing.
Example:
1) Open Photoshop.
2) Select two colors: white/white.
3) Create two blank documents, each with an empty Layer 1.
4) In one document, add a layer mask to Layer 1. The colors should have been automatically switched to black/white as the layer mask is selected.
5) In this document, use the gradient tool to fill the layer mask with black/white.
6) Switch to the other document, and notice that the color selection is again white/white.
7) In this other document, use the gradient tool to fill Layer 1. Notice that the layer is filled with black/white instead of white/white as selected.
I find that the color fill vector mask previews within the layers panel are not as useful as they were in CS5. Having the vector path along side the color swatch worked better.
View 3 Replies View RelatedI'm on Win 7, 64 bit, and CS6 (released). I've got the Spot Healing brush active and I Shift + Right-click to bring up the Blending options. I cannot change to Luminosity. It will change in the drop down box on the tool bar however.
When I first noticed, it was Lighten that it wouldn't change to. I've rebooted the PC a couple of times and now it seems to be the Luminosity mode.
when trying to use luminosity selection keyboard shortcut and it dosent work . On pc i should be: ctrl alt ~ but nothing happens - no marching ants. Mine ~ key is positioned to the right on my keyboard just beside the return buttom. Could it be that im using the wrong key here or.... thanks for any surgestion. (Maybe there is another way to make the luminosity selection if it is my keyboard short cut that dosent work.)

View 6 Replies View Relatedim trying to make an adjustment to one section of my footage.i followed other instructions elsewhere about making a mask on a solid and then linking the solid to a null object, which has tracking footage (i was thinking i could motion track a mask?)
so i did that, but tracking motion doesnt work, the mask moves everywhere so i went in and moved the mask points at keyframes, which was annoying. but now i can't add adjustments to the solid where the mask is. i turned the solid into an adjustment layer but adding color correction adjustments doesn't work.
i have to use after effects by the way. basically tl:dr i need to color correct one section (or the masked part) of my footage. how can i do that in AE?
also is there an easier way to motion track something that goes completely off screen or out of the comp window? cause its a handheld shot and theres like a pan, and im trying to track the mask but it doesnt really work or stay around the area it needs to.
