### 4/5 — Perfection minus 1

*2025-11-26*

Love this app!! Every landscape, sunrise, sunset, twinkling lights photo I have pass through this app before I’m satisfied. 
Please update app to save location metadata. 
Im constantly copying and pasting location data for each of my thousands of outdoor photos that I edit through Radiance+. 
Please and thanks

### 4/5 — 希望Gainmap支持新标准

*2025-11-12*

希望Gainmap的方式支持新的iso21496-1的标准

### 1/5 — Error loading images

*2024-04-28*

I really want to love this app. But when I select a photo to edit, it more often than not gives the following error message: “Cannot load representation of type public.”

### 4/5 — Única solução para restaurar fotos que eram EDR antes do iOS17

*2023-11-29*

Contexto: o iOS 17 simplesmente quebrou o EDR em todas as fotos que eu tirei com o meu antigo iPhone 11 Pro, como se nenhuma foto mais tivesse o “efeito” de brilho. Somente com este app consegui restaurar as fotos como eram.

Porém, mesmo salvando em heif, os arquivos ficam muito maiores do que originalmente eram utilizando o formato da Apple mesmo (se não se importar com perda de qualidade/compressão na hora de salvar a foto, ignore esta parte)

- Sobre função de processamento de múltiplas fotos, testei e os metadados (data da foto, localização e fuso horário) se perdem e não há um guia preciso do valor a ser atribuído (apenas um slider sem o valor numérico, tem que chutar o que é o aproximado do que se costuma colocar nas fotos). Salvando foto uma a uma, nada se perde dos metadados. Portanto é um ponto a se melhorar.

### 1/5 — Waaaaay tooooo expensive

*2023-10-28, version 1.3.4*

The price is ridiculous for what the app offers.
Total joke. What are the developers thinking? Becoming millionaires over night with such a simple app? Insanely greedy!

### 4/5 — Pretty good solution if…

*2023-10-27, version 1.3.4*

… you want your photos on HDR capable devices to glow. For batch processing the sliders for amount and Balance need to be adjusted for a less powerful effect. The auto function is a bit too harsh for me. 

Compared what other apps can do the price for Radiance is a bit too high

### 1/5 — Cannot adjust HDR on certain area

*2023-10-11*

Also lightroom now offer free HDR photo editing now, don't know this app still cost 30 dollar

### 2/5 — very overpriced

*2023-09-27, version 1.3.4*

does what it says, but reduces free usage to 75% quality HEIF and a huge watermark.

The Quality Setting being paywalled, that I can get behind, but a 3€ monthly subscription or 35€ one-time purchase is way too much for an not actively anymore developed app that does one trick - the massive watermark makes it basically useless without shelling over the huge subscription fee.

Suggestion: Remove the watermark from the free tier, or better yet: set a 5€ or lower one time purchase price - only that would be reasonable.

### 4/5 — super cool !

*2023-09-11*

any way you can make this work with videos ? would be amazing. thanks. (:

### 4/5 — Great results but can’t share with others

*2023-07-19*

When I try to share the HEIF files it generates with others on iMessage it sends as just SDR. Unsure why. Sending as a video works but that’s a bit clunkier and not ideal. 

Is this intended behavior? Is this a known limitation?
