noise HDR

Hi, I am beginning to use Lightroom for real estate. If I merge 3 photo's with different adjustments I'll get a weird glitchy greeny photo. It look terrible. The photo's are clear, but also Photoshop merges this into ugly colours. What is it that I do wrong? I just followed the steps on youtube. Importing photo's, stack and than HDR merge.

A few questions just to narrow down the issue a bit:

a) Did you shoot originally in Raw or in JPG?

b) Have these 3 photos "with different adjustments" been differently edited in the computer, or have they originally been shot as separate exposures using differing 'real' exposure settings (say, 3 different shutter speeds when all the other exposure settings are kept constant)?

c) When you say "Photoshop merges this into ugly colours" are you in fact using Photoshop to do the HDR merge, or are you using the built-in function of Lightroom Classic?

a) JPG

b)  "real" different exposure settings

c) Lightroom classic or lightroom cc merging built in function

The most efficient way to troubleshoot this is to share the original photos by attaching them to your reply here. (You may need 2 or 3 separate replies.)

Hey there! I recently started working with Lightroom for my too, and I ran into the same problem at first. Here’s what helped me figure it out step-by-step:

• Check Exposure Differences: Make sure the exposure differences between your 3 photos aren’t too extreme. If one photo is way darker or lighter than the others, the HDR merge can create weird, glitchy colors (like that green you’re seeing).

• White Balance Matching: Before merging, make sure all 3 photos have similar white balance settings. Sometimes if one has a much warmer or cooler tone, the merge goes crazy.

• Lens Corrections First: I usually apply lens corrections before merging. It helps avoid any weird warping or color shifts after HDR merge.

• Use ‘Deghosting’ Carefully: In the HDR Merge options, try setting Deghosting to 'Low' or 'Medium'. Too much Deghosting can sometimes introduce strange artifacts.

• Watch the Stacking: Double-check that you’re stacking the exact three versions of the same shot. Sometimes stacking a slightly different frame messes everything up.

• Post-HDR Edits: After merging, the photo will still need a bit of tweaking. I often adjust contrast, saturation, and white balance again to make it look clean and natural for real estate listings.

I'm still learning myself, but doing these steps helped my real estate agency photos look way more professional without the ugly colors. Hope this helps.
