How To Download Chroma Profiles Free

This Intelligent Profile & Preset pack includes 1 set of hand-crafted profiles and 6 categories of presets: Profile Selection, Tone Refinement, Color Calibration, Color Mixer, Masks, and Color Grading.

No. These profiles and presets can be adapted to your current workflow if you already have a good thing going. However, you may find is that they help speed up your RAW editing process if you adapt to the way these profiles and presets work together.

Since Raw data can only have one instance of a given slider at a time, these presets and profiles will modify the work of the image you use them on. If you open a RAW file you have already done a lot of work to and you want to save it, I recommend using a snapshot to save your progress before you start using these Profiles and Presets. The beauty of a snapshot is that after you make other modification you can quickly look at them side by side..

First, I have my original pair of profiles built for scans of transparencies (aka chromes), each with the same gamut, but different tone curves. Second, I have a newer quintet of profiles built specifically for use with digital cameras, all sharing the proprietary, perceptually linear tone curve of the Chrome Space 100 transparency profile, in a useful and very carefully crafted progression of gamut volumes. The middle one of the quintet, DCam 3, is also particularly well-suited for scans of color negatives. Lastly, I've added a Monochrome working space profile which shares the same tone curve (a zero gamut "space") which can be a nice complement to my DCam spaces and Chrome Space 100 when doing B&W printing, on account of its sharing the same tone curve. I include it now in all of the sets with master spaces which share its tone curve. Its same function is best met by Adobe's Gray Gamma 1.8 and 2.2 profiles when using master spaces with those tone curves, including Pro Photo and Adobe RGB, respectively. These are my master spaces:

5) DCam 5, J Holmes set: The fifth and largest of my five new spaces specifically for digital capture, DCam 5 is useful as a special-purpose, extremely large gamut space for digital camera captures and other RGB imaging work. It has a gamut volume and shape just sufficient to perfectly encompass the entire human visual gamut. Like most of my spaces it uses my proprietary tone curve for optimal perceptual linearity. The net, Lab-constricted gamut volume of this space is 324% larger than DCam 1, 278% larger than sRGB, 161% bigger than Adobe RGB, 112% larger than DCam 2, 95% bigger than Chrome Space 100, 63% bigger than DCam 3, and 25% bigger than DCam 4. Its non-Lab-constricted gamut is about 8% larger still. This space, like DCam 4 and ProPhoto, should generally only be employed with 16-bit per channel image data, given its great size. DCam 5 provides a lot more headroom than DCam 4, though this range of added headroom is sparsely populated by typical image colors, so under most circumstances it should not be particularly useful. It may prove useful, however, as a space into which to do batch RAW conversion, so as to defer the handling of clipping issues until later on. After years of looking at the way RGB spaces are limited in their ability to cover the CIE chromaticity diagram's visual gamut range by the inability of the blue coordinate to be placed below the x-axis, I just decided that I wanted to make such a profile, and the exact coordinates necessary to just fully encompass the visual gamut were the most obvious and appealing design for such a giant space. Perhaps others will find uses for it which have not occurred to me. It is available without chroma variants as part of the Eight Master Spaces set, which goes for $30.

10) Eight Master Spaces set: No chroma variants, just all of my master spaces. These can be useful in a number of ways, either just as better working space alternatives or as a good way to scope out which chroma variant set(s) to buy.

Electronic cigarettes (e-cigarettes) are growing in popularity exponentially. Despite their ever-growing acceptance, their aerosol has not been fully characterized. The current study focused on evaluating e-cigarette solutions and their resultant aerosol for potential differences. A simple sampling device was developed to draw e-cigarette aerosol into a multi-sorbent thermal desorption (TD) tube, which was then thermally extracted and analyzed via a gas chromatography (GC) mass spectrometry (GC-MS) method. This novel application provided detectable levels of over one hundred fifteen volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs) from a single 40mL puff. The aerosol profiles from four commercially available e-cigarettes were compared to their respective solution profiles with the same GC-MS method. Solution profiles produced upwards of sixty four unidentified and identified (some only tentatively) constituents and aerosol profiles produced upwards of eighty two compounds. Results demonstrated distinct analyte profiles between liquid and aerosol samples. Most notably, formaldehyde, acetaldehyde, acrolein, and siloxanes were found in the aerosol profiles; however, these compounds were never present in the solutions. These results implicate the aerosolization process in the formation of compounds not found in solutions; have potential implications for human health; and stress the need for an emphasis on electronic cigarette aerosol testing.

Modelling of analyte profiles and band broadening generated by interface loops used in multi-dimensional liquid chromatography. / Moussa, Ali; Lauer, Thomas; Stoll, Dwight; Desmet, Gert; Broeckhoven, Ken.

N2 - Currently, the shape and variance of the analyte band entering the second dimension column when injected from an open loop interface in two-dimensional liquid chromatography is not fully understood. This is however important as it is connected to several other variables encountered when developing 2D-LC methods, including the first dimension flow rate, the sampling (modulation) time and the loop volume. Both numerical simulation methods and experimental measurements were used to understand and quantify the dispersion occurring in open tubular interface loops. Variables included are the analyte diffusion coefficient (Dmol), loop filling and emptying rates (Ffill & Fempty), loop inner diameter or radius (Rloop) and loop volume (Vloop). For a straight loop capillary, we find that the concentration profile (as measured at the loop outlet) depends only on a single dimensionless parameter and the ratio of the filling and emptying flow rates Fempty/Ffill. A model depending only on these two parameters was developed to predict of the peak variance resulting from the filling and emptying of a straight capillary operated in the first-in-last-out (FILO) modulation mode. Comparison of the concentration profiles and the corresponding variances obtained by either numerical simulation or experiments with straight capillaries shows the results generally agree very well. When the straight capillary is replaced by a tightly coiled loop, significantly smaller (20-40%) peak variances are observed compared to straight capillaries. The magnitude of these decreases is not predicted as well by simulations, however the simulation results are still useful in this case, because they represent an upper boundary (i.e., worst-case scenario) on the predicted variance.
