You have acknowledged that yourself in the comment that suddie1215 quoted where you note that Photoshop can replace a background.īitmap definition: "A representation, consisting of rows and columns of dots, of a graphics image in computer memory" There is a structural difference in the way to two program function. LR is a parametric editor while Photoshop, Elements, etc. The only time one needs an additional editor such as Photoshop is when one wants to truly distort reality, such as for background replacements and things like that.Īmazing what a good imagination without considering reality can do. Lightroom is a bitmap editor, and a much more effective one when one considers the ease of use of its many tools and it's excellent all visible user interface. Sure some rough selections can be made in a parametric editor but not nearly with the precision available when actual pixels can be selected. It is also the absence of pixels in raw files that result in the inability to select specific elements precisely. The editing one does to an image file, including a raw one, is clearly affecting the above.Ī bitmapped file can be edited in a parametric editor (the editing instructions are saved to the file header space) but a raw file certainly cannot be edited in a bitmap editor without first being converted to a rendered file format. rasterized or bitmapped or rendered) until the file is exported in an image file format such as JPEG, TIFF, PSD, etc.ĭefinition of bitmap: "A set of bits that represents a graphic image, with each bit or group of bits corresponding to a pixel in the image." The raw sensor data isn't converted to pixels (i.e. Raw files cannot be edited in a bitmap editor since raw files consist of sensor data and metadata (describing how the sensor data should be interpreted), and not actual pixels. I could start with the assertion that "Lightroom is a bitmap editor." That's absolutely incorrect Lightroom is a parametric editor.
