What to Type for AI

Why Your AI Images Look Fake—and How to Fix It

AI image generators are powerful, but they betray themselves instantly if the color temperature is off, the aspect ratio doesn't match your feed, or the post-processing doesn't align with your existing aesthetic. Your followers can spot the difference between real and generated in milliseconds—not because the image is bad, but because it breaks the visual contract you've established.

The fix isn't more prompting. It's applying the same color science and finishing discipline you use on real photos. Specific color temperature ranges (3200K for warm interior shots, 5500K for daylight), exact aspect ratios tied to your feed layout, and Lightroom adjustments that echo your existing preset—these details collapse the uncanny valley and make generated images read as authentic photography.

This guide walks you through the technical settings that make the difference, with real failure points and how to avoid them.

Color Temperature Is Everything

The single biggest tell that an image is AI-generated is color inconsistency. Real Instagram feeds maintain a color temperature signature—warm, cool, neutral. AI generators don't know which one you use. Work backward from your best-performing posts. Open three high-engagement images in Lightroom and check the temperature slider. You'll likely see a range (e.g., 3800K–4200K for warm accounts, 5200K–5800K for bright/minimal accounts). Use this as your anchor. When you generate images, specify the exact range in your prompt: "soft warm tungsten light, 3800K" or "bright daylight, 5500K, minimal shadows." Then bring the generated image into Lightroom and match that temperature slider to your anchor. Don't eyeball it. Use the number. This single step removes the "clearly AI" feeling that kills authenticity.

Aspect Ratios Control Feed Rhythm

Instagram's algorithm reads your feed layout. A mixed bag of aspect ratios breaks the visual rhythm—1:1 squares, 4:5 portraits, 16:9 landscapes don't belong together, and followers feel the discord. Real photographers shoot in a consistent format. Lock yourself into one or two aspect ratios before generating. If your feed is 80% 4:5 (portrait, full-width mobile), generate everything at 4:5. If you mix 1:1 and 4:5, commit to the ratio before you prompt. This isn't creative limitation—it's the constraint that makes cohesion possible. Specify the ratio in your AI prompt: "1080×1350 pixels, portrait, 4:5 aspect ratio." Mismatched ratios stretched or cropped in-app always look amateur. The dimension consistency alone signals 'this is intentional.'

Post-Processing Settings That Match Your Aesthetic

A generated image drops into your feed next to real photos. If the contrast, saturation, and shadow depth don't match, it stands out immediately. You need to finish it with the same adjustments you use on authentic content. Take one of your most-liked recent photos and document your Lightroom or VSCO settings: exposure, contrast, highlights, shadows, clarity, saturation, vibrance. Write down the numbers. Now apply those same settings to every generated image before posting. Don't adjust per-image—use the exact preset. This sounds restrictive but it's actually liberation. Your followers see consistency, not variety. The algorithm rewards feeds that feel cohesive. A generated image with your preset applied vanishes into the stream.

Common Mistake: Overprompting for Realism

Photographers often try to make AI images more 'real' by adding technical jargon: "shot on Canon R5, f/2.8, ISO 400, soft natural light, Canon color science." This backfires. AI doesn't understand camera equipment specifications the way you do. It hallucinates lens artifacts that don't read as real—they read as overcomplicated. Keep prompts simple: subject, setting, light direction ("warm golden hour from left"), and mood ("minimal, clean, editorial"). Remove camera names and settings. Let the color temperature and post-processing do the technical work. A minimal prompt + rigorous finishing always outperforms a verbose prompt with vague post-processing.

Feed Integration: The Color Anchor Test

Before posting a generated image, screenshot your last five posts in a 2×2 grid. Drop the new image into the sequence. Does it feel like it belongs? Or does it pop visually? Pop = color temperature mismatch, aspect ratio jarring, or saturation too high/low. Fix in Lightroom using your anchor settings. The image should blend seamlessly with real photos. Your audience shouldn't be able to point to which is generated without zooming into texture. Do this test three times with three different followers (or trusted friends who know your work). If they can't spot the generated image, you've nailed the integration. If they can, the color science or finishing is off.

Posting Rhythm Without Calling Attention

Generated images work best scattered among real content, never in clusters. A block of four generated images in a row reads as automated and signals you've outsourced your feed. Alternate 2 real + 1 generated, or 3 real + 1 generated, depending on your shoot frequency. If you're using generated images to fill gaps between shoots, make the posting schedule visible to yourself (not your audience). On a spreadsheet, mark which images are real and which are AI. Aim for 70% real, 30% AI max. This ratio feels intentional—like you're expanding a shoot with carefully curated companion shots—not like you've replaced photography entirely.

FAQ

How do I know if my color temperature range is right?
Open your last 10 best-performing posts in Lightroom. Screenshot the Temp slider value from each. The range you see (e.g., 3600K–4100K) is your signature. Use that range for all generated images, then finish them with Lightroom, matching the exact number from one of your real photos.
What if my feed has mixed aesthetics (some warm, some cool)?
Your audience still sees a dominant theme. Pick the aesthetic that appears in 60%+ of your posts. Generate everything to that standard. If you genuinely alternate warm and cool, create two color-temperature presets and alternate generated images with the same deliberation you'd use for real shoots.
Should I disclose that some images are AI-generated?
Legally and ethically, yes. Use a consistent disclosure method (link in bio, caption note, or bio tag) so followers know your process. Transparency builds trust. Followers care less that you use AI tools and more that you're honest about it.
How do I prevent generated images from looking obviously edited?
Oversaturation and unnatural contrast are the biggest tells. Keep saturation +5 to +15, contrast +10 to +20. Let clarity sit at 0 to +10. Subtle adjustments that echo your existing preset will blend seamlessly. Heavy editing that's different from your real photos always stands out.
Can I use the same prompt for multiple images?
Yes, but regenerate it 3–5 times with small tweaks (different angles, different times of day noted in the prompt, different primary subject). This creates variety without losing color temperature consistency. Post them across different weeks so they don't cluster.
