Announcing: Tip of the Week with Dylan Kotecki – Every Friday

Posted in

Tagged with

I’m incredibly excited to bring you this new weekly series. I plan to provide you with these tips and tricks for ON1 Photo RAW in both video and written articles. The content for these ON1 Photo RAW tips and tricks will be from the requests I see in the ON1 Facebook Group, help requests submitted to our support team, through my own experience using the software, or some of the hidden secrets in ON1 Photo RAW. I hope you learn something new and valuable each week!

Today, I’m going to show you how to easily modify tonal ranges in your photos using the Tone Curve. The Tone Curve is the perfect tool for adjusting shadows, highlights, and midtones when editing your photos. I feel it’s a must-have tool for photographers looking to take their photo editing to the next level. I show you the basics of the Tone Curve and how to quickly make tonal adjustments. By using different points, you can adjust specific tones, allowing you to have complete control of the overall tone of your photo. Once you have set your overall tone, you can also use the Tone Curve to remove or reveal red, green, and blue in your photo to create unique split toned looks.

If you have ideas or requests for tips and tricks or if there is something you want to learn more about in ON1 Photo RAW, please feel free to leave your requests in the comments. I will do my best to deliver.

    Thanks for the article. I’m very comfortable with curves, because in the early days of PS it was the preferred way to go to get your WB right “by the numbers” and/or color matching different shots. I won’t go into that because ON1 doesn’t let you specify the target value (on the Y axis) for a selected input value on the X-axis.

    More important is the question what is actually changed when you modify the curve. Is it just luminosity (L in the Lab or HSL color models) or does a modification of the curve ALSO change saturation and/or the Hue/ab values.

    I remember tips for PS that recommend switching from RGB to Lab mode before using Curves. Some other image processors (C1 ?) have a Luminance selector in the Curves tool.

    Wrapping up: what’s actually happening under the hood (what’s the internal color model and how is it affected by Curves) when you use Curves in ON1?

    To make up for all the difficult questions: in the near future I’ll post an article how you can reproduce a very classic effect for B&W pictures with Curves.

      Curves are one of those tools that are pretty generic across all software.

      Here’s what Curves does–it’s an intuitive way of basically creating a look-up table for the effected channels. With the bottom axis representing the input value and the vertical access representing the output value. So if we create a center point in the Curve this is a value of 0.5. If we drag the center point down halfway, what we’ve done is tell Curves “Map Input value of 0.5 to output value 0.25” and the rest of the values are interpolated around these key points (Top 1.0, Bottom 0.0 and the mid-point we’ve moved).

      That’s it.

      So, in OnOne PhotoRaw we can see which channels are effected by seeing which channels are available. In PhotoRaw we have a Composite (Global) channel and R/G/B channels. This tells us that the Curves filter in PhotoRaw is only working in the RGB color space and only changing the direct values of the associated channels. Curves is not doing anything in HSL space (I’ve never seen a curves adjust that works in HSL, and, due to the different math behind that color model I’d even guess that’s impossible). Curves in L*A*B* (YUV) space are a great feature in Photoshop and Affinity Photo, and I’d love for L*A*B* curves to be added to PhotoRaw, but, if they were the curves themselves would still be pushing the values of three channels – in the case of L*A*B*/YUV those channels would be Luminance, Green/Magenta and Yellow/Blue.

    Nice tuto.

    About ED question, i use curve in luminosity mode. If it helps…

    A tool is missing in ON1 curve : targets like photoshop so we can select with an eyedropper a dark and a light tone of a regions of the image

    best regards

    The value of this quick tip was to give me a kick in the seat to use a terrific tool that I have been ignoring for a few years. Thank you.

    “Under-rated?” Kind of makes me giggle because Curves are so powerful and flexible they should be the absolute first color correction tool any photographer, digital artist or video artist should learn! So it’s good to see this video reminding people that PhotoRaw has ’em.

    Good walk-through of the tool. I’ll agree with another user here that adding eyedroppers to the curves would make them easier to use, and I’ll add in for myself if would be nice if PhotoRaw’s curves could be toggled into L*A*B* color space (or add a different “L*A*B* Curves filter in Effects/). This is an important enough feature for me that, after dropping Adobe, and working through several different other programs, including PhotoRaw, GIMP, KRITA, PD Howler, all my varied VFX software, etc, that I ended up buying Affinity Photo because it’s the only other (non-Adobe) program I can find with L*A*B* color curves, and I can do 90% of my global adjustments with just a single L*A*B* color curve on a top layer…

    Yes, feature requests should go in the proper section of the forum, I know. :-D

    Wow, finally explained so I can understand it. As a rookie it was extremely helpful to understand how it works. Thank you and look forward to the next tip.

      Jose, I agree with you 100%. I always glossed over the Tone Curve Tool in other programmes as I just never understood it.

    Great video and very much appreciated. You really captured the art of explaining some complex methods and I, for one, certainly learned something new about the tone curve within ON1 RAW.
    Thanks so much. Can’t wait to see what you have next time.

    Dylan, keep these type of Tips coming. You have explained this Tool tip in such a way that I now understand. Will be putting it to use in the morning on some photo edits I have to do. Thank you so much
