  • When converting from a wider gamut color space to a narrower color space, you need to make decisions on how to map that larger gamut into the smaller gamut. If all of the colors fit into the ...
  • Another interpretation of the result is that if you your final deliverable is sRGB, then you should work in sRGB Working in a larger gamut, and then converting before printing is problematic. Let's ...
  • No. Generally when we discuss "image quality" we are concerned about the quality of the overall image, not the quality of individual pixels. For an extreme example, consider a 4 pixel full frame ...
  • Replied in 5Ds Crop Mode
    The resolution is the same whether you shoot in crop mode, or shoot full frame and crop in Photoshop.  In crop mode, the JPEG has less than 50MP. RAW files are always full frame. If you are ...
  • It seems counter productive to carefully adjust all your colors to exactly what you want, and then use the standard Relative Colorimetric conversion to shift all the colors to something else, that ...
  • You should choose to use a filter when the advantages of the filter outweigh the disadvantages. Polarizer and Neutral Density filters have the same disadvantages as UV or "protective" filters, but ...
  • If that's how you prefer to clean glass, then you should be using filters. Personally, I prefer to use a microfiber cloth for cleaning glass. A absolutely agree.  I have some screw mount Pentax ...
  • This is a beginners forum. If you work in a wide gamut color space, and then convert to sRGB, you need to pay attention to the conversion.  You should have a good understanding of colorspaces so ...
  • As a general rule you will be worse off if you start in a wide gamut colorspace like AdobeRGB and then convert to sRGB. Side note: The colorspace choice is irrelevant until you convert the RAW ...
  • What good is a pristine lens if you are shooting through a scratched filter? As a general rule, the front element of your lens will have better coatings and be stronger than your filter. You are ...
  • At $25, the coatings on your filter are likely not as good as the coatings on your lens.  This filter is likely very fragile, you should probably put something in front of this filter to protect it. .
  • Yes.  Canon LP-E6N and LP-E6 batteries are interchangeable, and both can be used in the 7DII. This is documented on page 40 of the 7DII instruction manual: " Installing and Removing the Battery Loa ...
  • The issue is that you have been confused by the whole "equivalent focal length" mess.  Focal length is not a measure of field of view. A 100mm lens on a crop body has the same field of view as a ...
  • Do you have any friends with DSLRs? If so, there are advantages to getting the same brand they have. One nice advantage is that you can borrow lenses from them. Another advantage is that they will ...
  • Because "crop factor" is a way of comparing field of view .  Crop Factor does not affect focal length. Take a 100mm lens off a full frame body, and put it on a 1.5X crop body, and it is still a ...
  • We seem to agree on most issues, and disagree on a few important ones. If the print is small enough that the expected differences are below the visible threshold, then yes, a double blind study ...
  • The way you quantify is you look at the fixed noise that is independent of pixel size, and noise added by other parts of the system. At some point the pixels are large enough that noise from other ...
  • But the pixel size has no effect on the number of photons collected for the image as a whole. Consider two cameras: one with 20 megapixels, and one with 5 megapixels. The 20 megapixel camera has 4 ...
  • There is a lot of confusion on this issue because frequently people are discussing different things when they say "noise". If we are looking at the performance of an individual pixel, then ...
  • Normal incandescent light bulbs provide good quality light, but they tend throw off a lot of heat. The yellow tinge is from a mismatch between the color temp of the light source and color temp the ...
