I am taking daily shots of a fig tree which is just in front of my kitchen window. At the end I would like to produce a video showing the fig tree blossoming and then loosing its leaves. I am realizing that the lighting is changing from one picture to the other. Is there a way to even out the lighting of all my pictures to a given average?

Let's say a have an image mask (see image shown below) where the white areas are the selection islands and then apply that to an image. What I want to do is get the average color for each selection island in that object. Just blurring gives you a gradient effect and if you blur too big, you just get a single color. That's not what I want.

How to make two pictures have the same lighting.
View 1 Replies View RelatedWe do research on the effect of fish food on the color change of the fish's skin. Therefore we observe the fish over multiple weeks and take their picture in our studio environment once a week. In order to track the color change of the fish, all other conditions (lighting, distance etc.) should be exactly the same so that we can compare the average color of the fish over multiple weeks.
The problem is as follows. We have created an studio environment with a light tent and three flashes and fixed them to keep the shooting conditions the same every time. However as you can see in the three images below which are shots of the same fish in three different weeks, the lighting is not the same. We think that since we do shoot 30 fish in each batch, the flash did not produce the same performance for every shot and we got different lighting in each shot.
How can we match the lighting of these shots so that we can compare the color of the fish? We already tried the color match tool however it is no use in this case. Since we want to keep the fish as it is and only adjust the slight lighting difference.
I hurriedly photographed the text in a greeting card and have uneven lighting and underexposure that I'd like to correct. Please see attachment, in which I've increased the brightness and contrast and then desaturated.
I've looked at tutorials on gradient contrast masks but I get lost part way through. Either I'm too much of a newbie to understand (highly probable) or maybe the tutorials are for older versions of GIMP. (I'm on 2.8.6 for Windows.)
Any way for me to recreate something like this picture?
I wish to recreate a similar effect as shown in this photo, the left side of another man's face is darker than his right.
I am in the process of adding lighting effects to one of my images. I'm trying to get a lightning effect, and decided to use Supernova off of the image's frame. This worked for full-frame layers, but on smaller layers, not so well.
What's happening is that I'm trying to get single objects in layers to have a lighting effect, but it's lighting up the transparent space around them, making a distinctly brighter area... well, it's better if I show you:
Base:
Adding the Effect:
The Unsatisfactory Result:
How to merge two or more specific layers together, that'd be fantastic.
I am comparing multiple scanned images and I need to find out if one image is darker than another. For example, if you print a document on 5 different printers and then scan those documents into photoshop 7, is there a way to quantitatively analyze how dark each document is. Can photoshop 7 tell you the average darkness of a selected area of an image? They will all be scanned on the same scanner so the only variable should be the printers. I need a numerical value for each, not just a visual comparison.
I am using Windows XP and photoshop 7.

Is there a relatively simple, automated tool in gimp to apply one picture's environment lighting properties to another picture?
So for example if i cut out an object from one picture that has pretty warm lighting environment, and put it in a cold light background it will look pretty out of place obviously, and this is what I would like to resolve.
I have 10 layers and I want to blend them such that the resultant flattened image represents the average colour. i.e. If layer 1 has a white pixel and layers 2-10 have black pixels the result will be 90% black.

View 2 Replies View RelatedWhat formula Civil3D uses to calculate the average slope of a surface?
The formula I am using is S = I*L/A
S = Average Slope
I = Contour Invertval
L = Length of Contours (ft)
A = Area of parcel (sq. ft)
I just had to do four parcel calcs and the percentage I find using the formula is always 1-3% lower than the percentage Civil3D spits out. I can't find anything about how Civil3D arrives at that number, it just appears. I assume that Civil3D is more accurate but I can't give that number to a client without knowing how the program arrived there.
I have been able to undertake this with other software and have desperately tried to find this same function in Civil 3D .
Is there a command that returns the average level of any particular surface within a specified area, for instance if we have a generated a large surface and then draw a square in the middle of the surface, can it calculate the average level within the square only?
I have 2 different surveys of the same area of ground. If i create a surface from each data set, can they be averaged into one suface? I know you can past them together, but how does it paste? the first one on the bottom and the second on time? I would like an average.

View 4 Replies View RelatedI need to analyze an image and read the value of each pixel, exclude the highest and lowest values (perhaps anything less than 10,10,10 and greater than 245,245,245) , then average the remaining. I may need to do this on each channel of RGB.
I can almost get a result blurring the sample and then using a large brush with the info tool, but is there any other method more direct and all inclusive?

There is a cloudy appearance over the subjects in the pictures that I have not been able to get rid of. Is there anything that can be done to the photo before scanning?

View 1 Replies View RelatedAny quick way of calculating average Parcel Area? I used to export to LandXML and do an area report in CSV. That doesn't seem to be working for me when I export out of C3D 2012.

We have to compute the average elevation along the front, sides and rear of a proposed building envelope to calculate the required set back.

I am trying to record an action to find the center of a polygon with the following commands
1. Select the object
2. Copy and Paste in Front
3. Select > Object > Direction Handles

All is good & well except that step 5 never gets recorded as an action step.
Is there a way to change an object's fill from a gradient to a solid color that is the average of that gradient? What I want to do is have a grid of squares, select them all and apply a colorful gradient to them as a whole, and then average each square's color so I end up with a pixelated look. Kind of like the mosaic filter in Photoshop, but in vector.

I have a Canon Rebel t3 and when I try to import my pictures they all have a pinkish hue to them. I have looked at all the settings and they are all set to their default.

Unfortunately, when I try to open this it says "Update not applicable".
View 1 Replies View RelatedOftentimes I face the need to restore a picture of a text document -mainly forms to fill- to something approaching the original document. This requires to remove all the grey parts and to have a result in black on white i.e. no other colors. It may also require some understanding of how characters are formed -regardless the language- to prevent white dots in the middle of a character
With the document restored, one can then fill the form with an editor so as to have it clearly (printed characters) and easily (because filled with a editor) filled
My question is how do you do that with Gimp.
