Photoshop :: How To Convert Scanned Color Negative Into Positive
Jun 21, 2013
I have just scanned a color negative into photoshop and lo and behold it comes up on screen as a color negative. How do i now convert it to a positive so that I can work with it.?
I am photographing 2 1/4 negatives with a CANON 50D and macro lens. Then in Photoshop CS3 I was looking for the filter to convert the negative film file into a positive file so I can work on it with Adobe and then print in on my Canon printer.. I have tried to sample the orange base color and take that out and then invert and then increased the contrast curve.
I have photographed some colour negatives in RAW. Any outline of a process as to how to convert these to positives using Lightroom v5. I have tried and failed!
I have created a column graph with a large amount of data. I would like to apply two different colors to the positive and negative columns. Whenever I click on a column and go to object>graph> the column section is unavailable. I checked to see if the graph had become ungrouped, even though I never selected it. If I select the graph as a whole it does not say ungrouped. When I select a column the ungroup tab is greyed out. Does that mean my columns are ungrouped?
I need a plugin that can invert positive and negative space with transparency.
Example: I have a filled square in the middle of a transparent image. I use the plugin, and the square is now transparent, where as the originally transparent space is now filled.
Visual example:
Of course, I need this to do more complex shapes. Also notice the blur is accounted for.
I can scan and preview an b/w negative but it will not show up on the work screen after being scaned. I can scan a b/w neg and then reverse it to a positive for printing !!!!!!
I want to image trace this photo to create logo. However the way the logo will be applied means that there can be no negative space less than .35mm or 1pt or the heat transfer will have them blend together.
How can I image trace while maintain all spaces (both positive and negative) are atleast 1pt sq?
I'm want to reproduce a differential housing. Therefor I need a part which is identical to the inside of the housing. In other words, I need a positive part inside of the housing.
I've tried to do this with Derived parts by placing the differential housing in a large block. But then I get a block where lining of the housing is missing. So i can't do anything with this derived part.
I have attempt to upload the file, but it is too large. Even when i try to compress it.
I am setting up a table to automatically calculate plumbing fixtures based on occupancy count.The problem I have is creating a formula for plumbing fixtures for B occupancy where toilets are required at 1 per 25 for the first 50 occupants and thereafter 1 per 50 occupants. (International Building Code)
A simple formula for 1 at 25 would be "value/25" whereby the value would be a cell content (occupancy number).
Taking this further with a formula like "(value-50)/50+(value/25)" works fine as long as the value (occupancy) is greater than 50.
If the value is less than 50 the first part of the formula (value-50)/50 creates a negative result.
Is there a way to convert a negative result of the first part of the formula to a 0 (zero)

I know this is possible in Excel with the "max" function
After scanning and opening a paper doc in Photoshop the image is distorted- ie its because i usually scan photographs for manipulation, i know this is due to scanner settings but i don't know how to change them there.
I have original watercolors that I have scanned but need to edit and work with in InDesign. I am getting a gray shadow or hue in the "white" areas between the color. I've tried everything I can think of to remove the gray cast but it seems to be messing with the original color and hue. I've tried scanning at 2400, messing with the contrast, shadow and highlights, curves etc, after 3 days nothing seems to work.
I scanned a logo that was designed with a pen. I've cleaned up most of the 'spots' from the paper, being not pure white.
Now, I would like to change the color. It was black, how do I change it to red or blue? I can't flood fill as you would imagine, because not every pixel has the same brightness.
What is wrong with my GIMP? This behavior persists in every 2.6 and 2.8 build I've tried, in fact I'm pretty sure I first discovered it somewhere in 2.4 .
It's GTK bug #644032 - certain adjustments made to the Hue-Saturation tool (with overlap) may have problems handling the red/magenta wraparound properly. Which was supposed to be fixed eons ago (and with exception of this one specific usecase, it already WAS - see GTK #527085).
It originally happened while trying to adjust the color balance on a scanned image containing ambiguously red/magenta hues (yes I know we have an actual tool for Color Balance, but I've never been able to quite wrap my head around what adjustments yield which results). I have attached a sample file demonstrating expected vs. actual results with this usecase. My GIMP is clearly screwing the pooch on these adjustments ... but HOW, because even when I browse the online git repo the relevant source code looks like it should work perfectly (I've even mentally stepped through it and verified correct results, unlike my actual GIMP).
Try performing the same adjustments on your GIMP (note which build and version) - do you get the same results I do?
Is there any way in Elements 9 to convert a color or color range to "transparent"? I want to change a white background of an imported image (a map) to transparent so only the non-white objects (lines and shapes) are present. The image is way too complex to select each area individually.
I scanned a document into PSP X5 and I am trying to use the materials palette to highlight (in red) certain spots on the document. The palette defaults to grey shades only. I reset the workspace to factory defaults and even tried the SHIFT-START - without luck. However, if I open any color images, the palette shows full color options. if this is a problem with how I scanned the document into PSP X5?
I scanned and live traced a drawing of mine. I want to add color to make it a proper vector illustration for example:
But when I try and change the colour of the outline of say the skin, this changed the outline of everythign else (hair, clothes) because the lines are all joined. How do I only change the colour of the outlines surrounding certain areas?
