This is the biggest complaint we’re hearing about the R6!! Photographers who are moving from the CANON MARK III camera body and switching to the new Canon R6 camera body are lost when it comes to perfecting their edits to the style they are used to.

I get it because this same issue happened when I switched from the Mark III to the Mark IV. 


When Canon made the switch from the Mark III to the Mark IV, they changed the RAW file type and that resulted in a dramatic shift in our post-processing. This is the same type of issue photographers are running into today with the switch from the Mark III to the R6. 


I’ve seen some very established photographers actually RETURN their R6 because they didn’t like the massive shift and they are defaulting to their Mark III again. 


That is totally fine but eventually…. like, several years from now…. they will need to transition. There WILL come a time when almost every photographer will have to go through the nitty gritty process of figuring out WHY images look different with a new camera and learn how they can replicate an edit that they love! My hope is that I can help make that transition easier! 


That’s why I’ve created this Youtube Episode!!! 

I took some of the nitty gritty process of comparing RAW files, assessing the differences and making notes on which sliders are affected the most and I made a video for you!!! 


This video doesn’t just address the Mark III to R6 issue, these tips can be used to determine the struggle between any two types of cameras. 


In this episode I’m sharing the foundational steps I took to solve the editing discrepancy between two different RAW file types.  


If you find yourself in a situation where you were shooting with one type of RAW file and now, a new camera body is causing you to have to change your editing approach, here are some steps to take to work through the struggle:


  • Assess the difference: These raw files need to be compared side by side! This is what I noticed about the two file types:
    1. The Mark III has more dimension and more highlight and shadow
    2. The R6 looks flat and boring and just overall dull!
    3. The R6 also has bland, dull whites
    4. Mark III has more vibrant colors in RAW


  •  Decide which file you need to match to! 

If you don’t have an action plan for how you’re going to approach this transition, you’ll find yourself recklessly moving your sliders all around without any strategy at all. This just leads to more confusion and frustration! In this video, this was my approach:

    1. Edit the Mark III RAW file to the edit I wanted
    2. Copy those edits to the R6 RAW file
    3. Tweak the R6 edit to match the Mark III edit
    4. Compare the sliders in each section to understand what needs to shift in my new R6 edits to achieve the Mark III look


When editing anything, I highly recommend editing the exposure and POP first (if you don’t know what I mean about POP and haven’t explored the Tonal Curve, you would THRIVE in the KJ Consistency Course! (link). 


Another tool that you saw me using in this episode was the KJ Preset Process (link)! This is the innovative Four-Step editing process that I created in Lightroom to empower photographers to grow in their consistency and their efficiency! Unlike traditional presets, the KJ Preset Process combines the power of presets AND profiles in a step by step system!! You can learn more about why over 4,000 photographers are using this process HERE! 


I hope this video provides some clarity and encouragement if you have ever struggled with how to edit during a camera-body transition or really have ever struggled in general with editing overall! 

Thanks for reading!

Nikhil + Paige Retro Inspired Wedding Day | One Eleven East

I just feel like I need to say…. prepare yourself. Prepare yourself for some of the most gorgeously styled details I’ve ever photographed. Prepare yourself for fun portraits and the sweetest ceremony and lastly, prepare yourself for some serious JOY!!


I bought the RF 100mm Macro because I wanted to compare it with my EF 100mm Macro! I’ve had the EF for YEARS but since I upgraded to the R6 last year, I’ve slowly been replacing my lenses with the RF models.

Should you buy the RF Macro?!


Danielle + Ryan A Luxury Dover Hall Estate Wedding

This Dover Hall Estate wedding was one for the books! Wow! Just incredible! From the planning to the florals to the dress and creative use of the property. It was just gorgeous!! We met Ryan and Danielle at their engagement session a few months back and we fell in love with them. They are truly as kind and thoughtful and sweet as they appear.


Rhett’s Eighth Month

Oh you are something!!!! We are starting to lose you around the house! You crawl under tables, behind couches and soon, I just know you’re going to discover the stairs! You will walk laps around the ottomans and you LOVE to pull up on everything. I’ve caught you multiple times trying to splash in the toilet and it’s just hilarious… your brother or sister NEVER attempted that!


This day was one for the record books. It was the first time we had photographed anything at the beautiful Ivy Rose Barn and let me tell you, it’s a dream! It was also the first time that I was able to meet Sharon and Turner in person!! This is SO rare for me!! Normally we’ve already met our KJ Couples beforehand but thanks to the pandemic, we never had a chance to!

Rhett’s Seventh Month

We’re in a quite a new season. Rhett’s seventh month has been the month where he decided to start moving! No cord, cup, small choking sized object is safe anymore! This happened literally the week he turned seven months and he has been on the go ever since.
