The basics of how digital cameras measure and codify light intensity and color, by Dr Becky Smethurst

Source: https://aatventure.news/posts/james-webb-space-telescope-stunning-new-images

I like to follow astronomy vlogs and news because I see that many of the technical developments and background theory of this field are often translatable to the parallel world of microscopy. 

Around one year ago I stumbled on a youtube video link explaining how digital cameras used in astronomy measure and combine color intensities. I like that the vlogger, the astrophysicist Rebecca Smethurst, manages to explain in a very simple way how CCD cameras work, how light is split through the use of Bayer filters, how the signal intensity in the different parts of the color spectrum is measured  and how these values are combined to form a composite picture. I know that this video is on the field of astronomy, but the technical explanation is well fitting for microscopy as well. I think it is an entry level explanation for students or microscopy enthusiasts in general. 

On a side note, I started following her channel because I think she explains what is happening on the fields of astronomy and astrophysics in a very simple and engaging way. I particularly liked her video about what an astrophysicist does at her/his job all day, because I know that most people outside academia do not know what scientists do on a day to day basis. I wonder if the particular day chosen for the video was an exceptionally filled working day (we also have many meetings every week in the field of neuroscience, but rarely do we have three seminar/journal clubs/meetings in the same day). She also published videos showing field work, how to get into the astrophysics career, etc, that could be interesting to people curious about how is the life of a scientist. 

She also published a couple of popular science books about astronomy, called Space: 10 things you should know (2019) and A Brief History of Black Holes (2022), that I find as quick and informative reads.

Opening Zeiss czi file format mosaic files in Matlab using bio-formats

  The issue: I often write scripts in Matlab to batch image processing tasks, and for that purpose I need to load confocal or axioscan Zeiss czi format image files. I use an open source package called Bio-formats . However, I frequently get two kinds of problems when using this library in Matlab: a) working memory problems (Matlabs Java memory capacity gets filled when the files are in the order of the GB size); and b) stitching problems. This post will only focus on the second issue (I will write later a separate post for the first). The problem is that, for a long time, when I tried to open czi image files of confocal images that were tiled, the bio-formats pack would open the tiles individually, but it would not stitch them as a single image.     Diagnose procedure:  I tried to download different versions of the bio-formats library, because according to internet forums like forum.image.sc , the latest version of bio-formats had that problem fixed. The v...

Possible solution for problems opening confocal files from Zeiss LSM 880 in Neurolucida 360 environment

  The issue : One of the regular users of Neurolucida 360 has noticed that some image files produced by the Zeiss LSM 880 (confocal microscope using ZEN black software) do not open. This happens rarely, but she had five examples of medium sized (tens to hundreds of MB sized, mosaics with multiple z-levels) files that NL360 could not open.  Diagnose procedure : I tried to open the same files in Fiji and by using Matlabs bformats pack (v7.0.0) and in both cases, I got error messages concerning corrupted data bytes. Nevertheless it was possible to open those files in ZEN blue lite version. That made me hypothesize that there are a few corrupted data bytes in the file, but that ZEN lite can bypass those data points. That lead me to the think that if I tried to save those files again using the "Save as" menu, the files would be saved with the corrected bytes version, and that would make the files whole again. Upon testing this procedure, the files were fixed and could open normal...

Opening multileveled TIFF images in Matlab

  The issue : this is a simple issue. I generally open single-leveled TIFF files in Matlab by simply using the function:    data = imread('example.tif'); However, if the tif file in question is multi-layered (3D), this command will only open the top layer and ignore the rest.  Solution : There are two possible solutions for this problem. 1. Using only one command (tested in MatLab R2023, documentation refers to being first released with R2020b):        data  = tiffreadVolume('example.tif'); The numerical array data will therefore have 3 dimensions (x,y,z). I got it automatically in the format uint8 when I tried. Between the two solutions, this one is the fastest. 2. Using multiple lines (maybe for versions prior to MatLab R2020b):      info = imfinfo('example.tif');   data = zeros(info(1).Width,info(1).Height,numel(info)); %preallocates the data array.   data = uint8(data);  %converts the array from double to uin...
