Intro
Generative Fill in Photoshop showed up in every other studio retoucher's workflow within a couple of months of release. The button works, the preview looks pretty, the client is happy. Until the client brings in jewellery worth half a million and says "this is a press sample, nothing leaves the studio before June 15". At that moment Adobe Firefly stops being a universal tool and becomes a problem nobody covers in the tutorials.
Local Stable Diffusion solves that problem at the root: everything is computed on your own hardware, nothing leaves for the cloud, GDPR and confidentiality clauses are not violated technically, because data physically does not leave the workstation. That is the core difference between the two approaches, and it drags everything else along with it: price, speed, control, quality on demanding cases like jewellery and watches.
In this article we break down how Adobe Firefly differs from a local A1111 or ComfyUI stack, when the subscription is justified, and when commercial retouching simply cannot be delivered without a local pipeline. No advocacy in either direction: each tool closes its own task, what matters is understanding which one.
What Adobe Firefly and Generative Fill in Photoshop actually are
Adobe Firefly is a family of generative models from Adobe, trained on licensed Adobe Stock content plus public domain. In Photoshop it is built in as Generative Fill, Generative Expand and Generate Image. The workflow is as simple as it gets: selection, text prompt, Generate button, three variants to choose from. Under the hood the image is sent to Adobe servers, processed there, and the result comes back.
Strengths: predictable quality for typical tasks, correct handling of shadows and perspective in most scenes, a legally clean training set, which matters for commercial use. Photoshop itself writes Content Credentials into the metadata stating that a fragment was generated, and many brands now require that under their internal guidelines.
The weaknesses follow from the same architecture. You do not control the model: whatever version of Firefly Adobe runs today is what you get. No LoRA tuned for a specific brand, no ControlNet, no inpaint with mask softness 0.35 at denoise 0.42. One prompt, one button, three variants. Fast for a draft, often not enough for a commercial final.
What local Stable Diffusion is (A1111, ComfyUI)
Stable Diffusion is an open model you can run on your own computer. Two things are required: a GPU with 8+ GB VRAM (comfortable from 12 GB, for SDXL and Flux 16-24 GB is better) and an interface. The two most popular ones:
Automatic1111 (A1111) is a web frontend that runs locally, opens in the browser at 127.0.0.1, and gives access to every model parameter: sampler, steps, CFG scale, denoise strength, ControlNet, LoRA, inpainting with mask, outpainting, upscale via ESRGAN or SwinIR. The entry barrier is higher than in Photoshop, but after a couple of weeks of practice it becomes a familiar tool.
ComfyUI is a node based interface where workflow is assembled from blocks, like in Nuke or Substance Designer. Each node is a separate operation: model loading, sampling, ControlNet, LoRA, post processing. Harder at the start, stronger in production: a graph you build once can run a batch of 200 frames without an operator.
Both shells are free, sources are open, updates ship weekly. Models are downloaded from Civitai or Hugging Face: base SDXL and Flux, plus community checkpoints for specific tasks (photorealism, product photography, portrait retouching).
Price: Adobe subscription vs one time hardware plus free software
We count over a three year horizon, because subscription models always look cheaper on a short window.
| Parameter | Adobe Firefly (via CC) | Local Stable Diffusion |
|---|---|---|
| Starting cost | 0 (if CC subscription exists) | 900-1800 USD (16-24 GB GPU) |
| Monthly | 40-70 USD (Photography Plan + Firefly credits) | 0 (electricity ~3 USD) |
| Over 36 months | 1440-2520 USD | 900-1800 USD one time |
| Generation limits | 1000-3000 credits/month, then paid | Unlimited |
| What remains after 3 years | Subscription works only while you pay | Hardware and skill stay with you |
In the moment a subscription is cheaper because you do not pay for hardware. Over time the local approach turns positive already in year two, especially when volume is high and Firefly credits run out. Plus an important detail: the GPU you bought serves more than generation. It also drives Topaz Photo AI, Gigapixel, DaVinci, Premiere, Capture One smart adjustments. It is a general purpose tool, not a single service.
Confidentiality, GDPR and cloud: why local is the only option for premium brands
This is the point where debate ends. Adobe Firefly sends the image to Adobe servers for processing. The terms of service state that Adobe does not use your content to train models (after the 2024 backlash), but the fact of transferring the image to a third party remains.
For most projects that is not a problem. For commercial work with confidentiality clauses or strict GDPR scope it is a blocker.
Typical situations where cloud generation is prohibited by contract:
- Jewellery brands before the public launch of a collection
- Fashion brand lookbooks before the seasonal launch
- Any samples marked confidential or pre release
- Corporate product photography under NDA (electronics, automotive, pharma)
- Government orders and work with restricted facilities
- Any case where personal data of the model appears in the frame and GDPR data minimisation forbids unnecessary transfer
The lawyer on the client side reads the contract, sees the clause "no information is transferred to third parties without written consent", and Adobe Firefly automatically falls out of the toolkit. Even if no leak actually happens, formally it is a violation, and in case of dispute the retoucher will be the one held responsible.
Local Stable Diffusion settles the question at the physical layer: the machine is disconnected from the internet while working (you can simply disable the network adapter), the image goes nowhere, no metadata leaves. To the lawyer you show the workstation spec, explain that Stable Diffusion works offline, and the matter is closed.
Control over the result: one Generate button vs 8+ parameters
In Photoshop Generative Fill gives a prompt and a button. If you do not like the result you can generate three more variants. If you do not like that either, three more. Essentially a roulette with limited influence over the outcome.
In Stable Diffusion, for a single inpaint operation you have at hand:
- Sampler (DPM++ 2M Karras, Euler a, UniPC, and a dozen more) defines the character of generation
- Steps (15-50) how many refinement iterations
- CFG scale (3-12) how strictly the model follows the prompt
- Denoise strength (0.1-1.0) how strongly the original pixel changes
- Mask blur the softness of the mask edge
- Mask padding how much context the model sees around the mask
- ControlNet (Canny, Depth, Normal, OpenPose, Tile) forced binding to the structure of the source
- LoRA a fine tuning adapter trained for a specific task
- Seed randomness control to reproduce a variant you liked
Comparison of what is in principle achievable:
| Task | Adobe Firefly | Local Stable Diffusion |
|---|---|---|
| Replace background | Yes, one button | Yes, with full composition control via ControlNet Depth |
| Outpaint missing part of the frame | Yes, limited | Yes, any size via outpainting |
| Preserve exact object shape | Often no, shape "drifts" | Yes, via ControlNet Canny or Tile |
| Change material, keep shape | Very limited | Yes, via img2img with low denoise + LoRA |
| Batch processing of 100+ frames | Only by hand | Yes, via script or ComfyUI workflow |
| Reproduce the result a month later | No, the model changes | Yes, seed + parameters are fixed |
For a draft control is not needed. For a final destined for print or a billboard it is critical.
Quality on jewellery: where Adobe hallucinates stones, where local holds pixel for pixel
Jewellery is a litmus test for generative tools. A stone has exact geometry, facets, reflections, laws of optics. Any mistake reads instantly: a diamond with six facets instead of eight, an opal with a wrong play of color, an emerald with a fantasy inclusion that is not in the real piece.
Adobe Firefly on jewellery behaves on the "make it look similar" principle. The model does not know that this is a particular stone worth 20 000 USD, it generates an averaged diamond. For a catalogue it sometimes works because the stone is small and details are not visible. For a close up, a website zoom, a print on a spread, it is fatal: the brand will not accept an image where facets are "drawn" rather than retouched from the real file.
Local Stable Diffusion with the right workflow plays on a different field here. The base logic: ControlNet Canny or Tile forcibly binds generation to the contour and tonal structure of the source, denoise stays in the range of 0.25-0.40, the model does not "invent" the stone again, it carefully refines what is already in the shot. Add a LoRA trained on the brand's references (if such a one is assembled), and you get the characteristic rendering of metal and settings.
In practice for major jewellery in production the stack looks like this: dust and micro scratch cleanup by hand in Photoshop, base dodge and burn by hand, background replacement or shadow extension via Stable Diffusion with ControlNet, final colour grading in Capture One or Photoshop. Without local control over denoise and masks this pipeline cannot be assembled.
Speed: 5 seconds Adobe vs 30 seconds local, but local can batch overnight
In the moment Adobe Firefly is faster. Generate in Photoshop returns three variants in 5-10 seconds, no model loading and no GPU warm up. Local SDXL on RTX 4090 gives one inpaint variant in 15-30 seconds, on RTX 3060 in 40-60 seconds. On a first pass over one frame the difference is noticeable.
The picture changes on volume. 200 catalogue frames, you need to remove a price tag from the same spot: in Photoshop that is 200 clicks on Generate, choosing a variant, saving. Three to four hours of continuous work. In ComfyUI it is an assembled workflow that runs overnight and by morning gives you 200 finished files with identical parameters and predictable result.
| Scenario | Adobe Firefly | Local A1111 | Local ComfyUI batch |
|---|---|---|---|
| 1 frame, single task | 10 sec | 30 sec | 30 sec |
| 10 frames, same type | 5 min | 7 min | 5 min + workflow assembly |
| 200 frames, same type | 3-4 hours of manual work | 1.5 hours semi automated | 90 min unattended overnight |
| Fine tune one complex frame | Impossible, only rerolls | 20 min with parameter tweaks | 20 min with parameter tweaks |
Operator time costs more than GPU time. That is why in production retouchers with a local workflow win specifically on volume tasks.
When Adobe Firefly is justified
No illusions: for a significant share of tasks Firefly is the better choice. The list:
- Social, stories, content with a short life cycle
- Previews and mood boards for client sign off
- Simple background replacement to a stock one
- Frame extension to a required aspect ratio
- Removal of a random object (a bottle in the background, a wire, a tripod shadow)
- Work without a confidentiality clause, where the formal side does not matter
- The retoucher works in an Adobe CC team and PSD file exchange is critical
- The brand requires Content Credentials in the metadata
In these scenarios launching local Stable Diffusion for a single mask is overhead without payoff.
When local is mandatory
Points where Adobe Firefly is unsuitable for objective reasons:
- Any work under a confidentiality clause before public release
- Jewellery, watches, premium optics where geometry is critical
- Fashion lookbooks before the seasonal launch
- Volume retouching from 50 same type frames (batch wins on time)
- Subtle retouching with denoise 0.2-0.4, where Generative Fill rewrites too much
- Work with LoRA tuned for a brand or a specific product segment
- Client requirement "no cloud AI services" (increasingly common in briefs)
- GDPR scope with personal data visible in the frame
- Reproducibility months later (seed + parameters fixed)
In these scenarios the local pipeline is not an alternative but the only technically valid way to deliver the job.
Hybrid approach: Adobe for drafts, local for finals
In a real studio both tools live in parallel. A typical workflow on a commercial project:
- Shoot, frame selection, base RAW processing in Capture One
- Draft composite and idea check via Generative Fill in Photoshop, to show the client a direction quickly
- Client sign off, direction locked
- Final pass locally in A1111 or ComfyUI with proper parameters, ControlNet, the needed LoRA
- Layer assembly, dodge and burn, colour grading by hand
- Delivery with clean metadata
Firefly closes the fast iteration, local SD closes the production final. This is not a competition of tools, it is a division of labour by stages.
Trends: where the market is heading in 2026-2027
Several directions already visible and only intensifying.
Local models catch up to the cloud on quality. Flux 1.1 Pro, SDXL Lightning, new community checkpoints on Civitai deliver results that a year ago were possible only in Midjourney or Firefly. The gap shrinks every three to four months.
Brands formalise AI requirements in the brief. Earlier a "no AI" clause was exotic, in 2026 it is a standard line in contracts with the premium segment. A share of brands demands the exact opposite: AI processing is allowed but only locally, with workflow logging for audit.
Subscription services rise in price. Adobe in 2025 increased Photography Plan pricing in several regions, added Firefly credit caps, split out Generative Fill into a separate paid module. The trend continues, because inference on generative models is expensive for Adobe itself.
GPUs get cheaper per VRAM gigabyte. RTX 5090, announced Chinese counterparts, more VRAM on the consumer segment make local AI accessible without a million rouble workstation. In a year and a half the entry threshold drops further.
The "local AI workflow" spec line appears in job postings. Studios hire retouchers with a specific requirement for ComfyUI or A1111 knowledge, because the client demanded it and the studio needs someone who can deliver. In a year this will be as basic a competence as knowing Capture One.
The conclusion is simple: subscription AI stays for fast and non critical work. Local becomes the professional standard in commercial retouching. Those who master it now will have an advantage on the market in a year. Those who postpone until the moment "when it is really needed" will be catching up under conditions when basic knowledge is already universal among competitors.
Master the local AI workflow for commercial retouching
The AI PRO course from gdefoto is a step by step programme on local Stable Diffusion for product and commercial retouching: installing A1111 and ComfyUI, working with ControlNet and LoRA, inpaint and outpaint for jewellery and product photography, assembling batch workflows for volume tasks, integration into the pipeline with Photoshop and Capture One. No filler, on real cases from a commercial studio, with focus on a confidentiality friendly process.
Programme, schedule and pricing: /lk/ai-pro/buy/
After two or three months of training you stop depending on subscription limits, you close work under confidentiality clauses in a technically clean way, and you take projects that competitors without a local stack simply cannot access.
