Photoshop :: Match Lighting Of Two Pictures For Scientific Research Project
Sep 12, 2012
We 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.
Is there a way to control color print quality that matches the in-canvas look of a part or assembly.
As a quick example, I have a Kelly Green wire visible within an assembly. When I print the assembly within a .idw drawing file, the Kelly Green turns very dark.
Is it possible to specify a particular lighting setting to be used when printing? I'm expecting to see color print output that matches closely to what I see when viewing either a model or an assembly.
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?
In VS X4 we do not have the ability to match the project properties to the specs of the source video. When editing "project properties", we only have two choices for compression (NTSC DVD and PAL DVD) which only allow a maximum resolution of 720. In X2 we had many more choices which included MPEG-2 where we could get up to 1920.
I thought it was rule number one to match the project properties to the source video. Maybe that is not so important anymore, but snapshots for freeze frames must be done in project mode to include any attributes. The resulting snapshot is the resolution of the project properties and therefore not the same as the orignal video. Once rendered, it will not look the same as it's parent frame. Maybe freeze frames are not important to anyone else, but they are to me.
I shoot with a Canon HV20, so I need 1440x1080. I have created an empty project in X2 with the correct properties that I use to start projects in X3 and X4. X4 appears to maintain the project properties once they are set.
I am editing old pictures. To save time I am scanning four pictures at a time. I'm using the marquee tool to crop each picture into their own layer via right click method and choosing "Layer via copy." After I'm done doing this for all four pictures, I have to hide all but one layer, trim the project to the picture size, save it. Then I undo the trim, and start over for the next picture to save.
Is there any easier way to save each cropped section as their own picture/project at the size of their crop without effecting the other pictures? Was wondering if there was a way to crop the portions I want out but instead of copy to layer method, I could just create a new project with that cropped picture?
I am trying to equating images in the best way in a PSPIMAGE Project. My base image (background) has a dimension of 640 x 480.
I inserted two pictures. By original configuration, picture A (200 x 266) is bigger than picture B (145 x 189).
- If I increase size of picture B (to achieve same size of picture A), this picture will loss quality. Isn't it (I'm not completely sure)?
- So, maybe could be best decrease size of picture A (to achieve same size of picture B). But it will "harm" my main "composition" of dimension 640 x 480.
It seems to be simple but I don't know what to do or by where to begin...
I made a project in after effect and it has alot of pictures. I'd like to delete the pictures from my project folder but when i do the pictures are deleted in the after effects project. Is there a way i can embed the pictures so i can delete them from my folder?
I opened a 1024x1024 image in GIMP, and manually broke it up into fully black and fully white sections. I'd like to output a file which is just a simple binary array of 8 bit numbers, such that every black pixel in the image has the value 0, and every white pixel has the value 1. This way, I can open it in my C program and then load the array into memory using the fread function.
I haven't been able to work out how to do this. I need to avoid using any files with metadata in them...And unfortunately, even the ppm format has a handful of characters at the beginning. Is there a way to do this?
In a lab the students get this kind of graphs to later be processed in an axial system: a grayed pencil draw, very delicate, with all the imperfections in weight, intensity, etc.
We need to obtain an uniform line (a solid one, without gray variations, same weight, etc)
Autotrace seems the best tools although the results appear a little irregular. What could be the best approach as we have hundreds to process?
Beginning with the scanning (more resolution?) and processing firstly in Photoshop?
1. i received a DWG that has a TIFF image referenced. This 30MB TIFF came in a separate folder (eTransmit) and the path is correct, but i cannot seem to grab the image in model space. the layer that has the xref is not frozen, and i can see the xref in the properties box and unload/load/detach, however i am unable to select or grab it. Was this done intentionally by the author to keep the image intact or is this property of transmitting?
2. The drawing coordinates is appearing in scientific notation and i need them to display all 9 digits. How do i change this?
why i can't not match properties (MP) multileader texts, as you can see on the pic, i want the Mleader text on the right to be the same size as on the left, they are in the same layer, same mleader style but when click MP to match with the one on the left, nothing happen?
I currently use Mep 2012 although my question I believe is general in nature. As a sheet metal contractor I do drawings that have many different entities at various elevations. Many times I use change propeties to match the propeties of on entity like a linetype to change another. What I really need to do is have the ability to use a similiar button and match or change the "Z" elevation of a specific entity just like I do for linetype, color etc.
I'm having issues with importing an image I created in photoshop that has a background transparency into another photoshop project. The part of the image that should be invisible, is not.
I have a Project Template that is used when creating a new project. I noticed that the Tool Palette in the Project Template and the Tool Palette in the new Project are not the same. How do I get the new Projects to pull the same Tool Palettes from the Project Template?
How can I change the way the Project Browser maps the creation of new projects?
Currently, the new project folder is created and named according to the Project Name prompt. We want the folder to be named according to the Project Number prompt...
I've built a project up with several smaller project file components. It's an easier way to create a video than editing one big project.
Opening the overall project and running it on screen is not a problem. However, when I try to create a smart package of the composite project, I get a consistent error message rejecting the process because of the existence of the component vsp's.
Is there a way to avoid the error and create a smart package from a project file that has smaller component project files?
I have to set up a project in Navigator so we can get started on it but I will have to go back and change the project number when we get it.
My question is how do I change the project no so that it re paths everything and reorganizes itself numerically in Windows Explorer...or should I just create a new project in Navigator and copy the files I need into the new project?
I used railing tools and created railing in the project files. i want to change rail and Baluster.i created metric baluster and rail from family and saved in the local drive. i used in to my project also it is working fine.
i want to use this railing to some other project. how to get it either copy past or revit link or any other way because the railing created in project file.
I want to take a sequence that I had in an old project and put it into a current project, but I dont want it to be one rendered file... i still want too see the fades and make changes to it...
I do not have vault installed and I am trying to add sub files to my project. As of now my project has to find many of my files and I do not want to copy and past them into my project folder as this will mess with my parts numbering system. I want only one part / assembly file per part. I assume that you can do this with the project dialog box or some other system tool I just can not seem to figure it out.
i´m having a problem opening a premiere pro cs6 project from another computer. My partner can open the project in her computer, but when she sends me the project by mail and i try to open it in my computer i I get t the mesasage " Cannot load project". I´ve tried importing the project into another project but it doesn´t work.
I am trying to download pictures in folders and sub folders into the LR catalog. The import brings all the pics in the subfolders over but when II click on the parent folder it shows not pictures or number of pictures in it.
I imported pictures to Adobe Lightroom and exported them to my memory card. Now my memory card is broke! Is there any way to retrieve those pictures from Lightroom. Right now they are saying missing.
I am trying to place pictures into my paragraph text so that the text wraps around the picture (like you can in Word).? Can anyone let me know how to do this in Photoshop 7.0 for Windows??
All I can find is how to wrap text around object (i.e. word on a coffee cup image itself) or putting the actual picture as fill for the font.?
how to do this? I have included a PDF of a sample of what I'm trying to do.
